Metso Outotec aims for higher capacities as ore sorting offering develops

The entry of Metso Outotec into the bulk ore sorting space arguably heralds the beginning of a new stage of market adoption – one that is focused on significant throughputs across multiple commodities.

In May, the mining OEM announced a collaboration agreement with Malvern Panalytical, a company that has been using Pulsed Fast Thermal Neutron Activation (PFTNA) technology onboard its cross-belt analysers to analyse and help divert ore and waste streams with improved accuracy.

Up until that announcement, Metso Outotec had mooted the benefits of bulk ore sorting in several industry articles. On the smaller scale, it had also renewed its ongoing agreement with particle ore sorting major player, TOMRA.

The company said its agreement with Malvern Panalytical, which has previously worked on bulk sorting projects with Anglo American among others, brought together its expertise in crushing and bulk material handling solutions with Malvern Panalytical’s ore analysis nous to offer an industry-leading portfolio of solutions for bulk ore sorting.

Rashmi Kasat, Vice President, Digital technologies at Metso Outotec, said in the press release that the pact with Malvern Panalytical would allow the company to meet the industry’s increasing sustainability and resource efficiency needs in an enhanced way in the early comminution stage.

“Sensor-based bulk ore sorting and data-driven analysis upgrades low grade or waste stockpiles, making them economical and far less energy-intensive to treat,” she said.

There are obvious positive benefits up- and down-stream of sensor-based sorting too, with the ability to carry out a low-cost mining method (upstream), as well as reduced capital investments in downstream equipment already shown with early-adopter projects.

That is before considering the relative energy and water reduction requirements that come with applying the technology.

Kasat later told IM that the company’s existing portfolio of material handling modules, crushing stations or mobile crushing equipment, as well as bulk material handling solutions, already “complement” the concept of bulk sorting.

“The addition of the bulk sensor is easily achieved,” she clarified. “The diversion mechanism will be included as well to be able to offer the whole plant out of one hand.”

With crushing stations – at least in the in-pit crushing and conveying (IPCC) space – that can go up to 15,000 t/h (see the company’s Foresight™ semi-mobile primary gyratory station), the prospect of Metso Outotec making a concerted effort to get into the bulk ore sorting space bodes well for the rising throughputs of projects.

NextOre recently claimed it had commissioned the world’s largest bulk ore sorting system at First Quantum Minerals’ Kansanshi copper mine in Zambia. This installation, which uses the company’s magnetic resonance technology, comes in at a 2,800 t/h-rated capacity.

Scantech, meanwhile, recently confirmed it has a GEOSCAN GOLD installation using prompt gamma neutron activation analysis technology for bulk sensing/sorting up and running that uses a diversion system at conveyed flow rates of more than 6,000 t/h.

Kasat, without naming a range, confirmed Metso Outotec was targeting “higher capacities” in line with the sensors available on the market. She also clarified that the agreement with Malvern Panalytical was “non-exclusive”.

“We will choose all our sensor/analyser partners strategically,” she explained. “Malvern Panalytical has a leading position and history in this field with proven technology for ore sensing. We will leverage our and their Tier 1 position in the industry for our bulk ore sorting offering.”

As the type of sensor to be employed varies based on several factors including mineralogy, plant capacity, application of bulk ore sorting, etc, Metso Outotec will identify the right partners for the right need, she explained.

The major constraints for these sensors are often measurement times and sensor penetration, according to Kasat.

“There are very few sensors out there that can do sensing of a 500-mm-deep bed of rock on a conveyor belt, moving at 5-6 m/s,” she said. “But our current and future prospective partners are working on developing the technologies to reduce measurement times without compromising the accuracy of measurement.”

The mining OEM is looking to, in most cases, provide ‘plug and play’ flowsheets for bulk ore sorting and then carry out the required customisation per sensor.

This plan reinforces Kasat’s assertion that there is no ‘one-size-fits-all’ concept in bulk ore sorting applications.

For new projects, the process could see the company start with metallurgical testing, progress to mobile/fixed pilot plants in the “backyard” to test the accuracy of the sensors for the given application, and then find the right solution for the customer’s use case.

Renato Verdejo, Business Development Lead for Bulk Ore Sorting at Metso Outotec, added: “For existing plants, we will install the sensor over the belt conveyor and analyse the results after selecting the right sensor for this sorting application.”

Metso Outotec intends to focus on major commodities like copper, iron, nickel and gold, among others, with applications such as waste/ore sorting, low grade re-crushing and beneficiation process optimisation.

Within this wide remit – and in line with its non-exclusive agreements with Malvern Panalytical and TOMRA – the company is also considering the combination of both bulk and particle sorting in flowsheet designs.

Metso Outotec, in 2021, renewed its ongoing agreement with particle ore sorting major player, TOMRA

“The combination of the superior throughput of a bulk application with the selectivity of particle sorting in a rougher-scavenger setup is something that can bring sorting to high volume mines in the future,” Kasat said.

“Plant concepts and flowsheets have already been conceptualised and we expect the first deliveries to be in pilot stations to test the sensors on site,” she added, saying that the tonnage requirements for bulk ore sorting sensor validation meant a bulk sensor would have to be piloted in the field to get statistically meaningful data about the properties of the deposit.

Metso Outotec’s crushing system offering will form the “base” for these solutions, with ore sorting optionality available to all customers, she said.

This sensor-based optionality also overlaps with another in-demand part of Metso Outotec’s business: IPCC.

The company’s dedicated team in Germany are responsible for this area, developing projects backed by comprehensive studies.

They – like most of the industry – are aware of the potential application for sensor-based ore sorting in IPCC projects.

Markus Dammers, Senior Engineer of Mine Planning for Metso Outotec and one of the team members in Germany, said there were applications for both bulk and particle sorting in IPCC applications, with the former likely integrated after primary crushing and the latter after secondary/tertiary crushing.

“Bulk ore sorting in an IPCC application should be integrated after primary crushing in order to recover marginal material determined as waste in the block model, or reject waste from the ore stream,” he said.

Bulk ore sorting in an IPCC application should be integrated after primary crushing in order to recover marginal material determined as waste in the block model, or reject waste from the ore stream, according to Markus Dammers

If integrated after secondary or tertiary crushing, it becomes less effective, with the ore’s heterogeneity decreasing every time the ore is rehandled, transferred, crushed, blended, etc.

“In this manner one can take advantage of the natural variability in the deposit, rather than blending it out, with bulk ore sorting,” he said.

After secondary and tertiary crushing, particle sorting may be applied as a “standalone or subsequent ‘cleaner’ process step”, he added.

With Metso Outotec open to the inclusion of ore sorting in fully-mobile, semi-mobile and stationary crushing stations within an IPCC context, the company has many potential customers – existing and new – out there.

And that is just in IPCC applications.

The company also has hundreds of crushing stations on fixed plant installations that could represent potential sorting opportunities.

Metso Outotec, on top of this massive install base, has a few advantages over traditional ore sorting vendors in that it understands the plant that goes around the analysis and diversion process associated with ore sorting; knows how important uptime is to its customers; and, through sophisticated modelling, realises what impact changes in the flowsheet will have up- and down-stream of such equipment.

“The key point here is to have all the equipment to handle and process the ore to feed the sorter and, later, having the technology to divert the material and retain the availability of the plant without changes,” Kasat said.

Energised by its Planet Positive aims of responding to the sustainability requirements of its customers in the fields of energy or water efficiency, emissions, circularity and safety, the company is now ready to flex its processing plant muscles to increase the industry’s adoption of bulk and particle sorting technology.

BEUMER completes acquisition of conveyor systems provider FAM Group

BEUMER Group says it has completed the acquisition of the FAM Group of Magdeburg, Germany, in the process, increasing its conveyor system and loading technology offering.

BEUMER, a leader in the manufacture of intralogistics systems for conveying, loading, palletising, packaging, sorting and distribution, signed the purchase agreement in early May, with the transaction legally concluding on June 9, 2022.

The BEUMER Group has held a stable position in the bulk materials technology market for decades and, with the acquisition of the FAM Group, the systems provider has significantly strengthened its market position in the minerals and mining sectors, it said.

The FAM Group is a manufacturer of conveyor systems and is an internationally operating, medium-sized group with 750 employees. The company is one of the world’s leading full-range bulk handling and processing equipment suppliers, able to plan, design and manufacture turnkey plants and systems for mining, extracting, loading and storing minerals, raw materials and goods.

In addition to expanding the BEUMER Group’s portfolio, FAM’s know-how and global positioning also complement BEUMER’s competence in the project planning of plants, BEUMER said. FAM brings not only planning and engineering, but the entire value chain to the BEUMER Group, including aftersales service.

The company concluded: “The BEUMER Group offers FAM a long-term perspective anchored on the highest possible quality, sustainability and innovation: for almost 90 years now, the BEUMER Group, a family-run and wholly self-financed company, has been developing customized system solutions for the mining industry, among others.”

Earlier this month, Rudolf Hausladen became the new CEO of BEUMER Group, succeeding Dr Christoph Beumer, who had led the group as CEO since 2000.

Datamine establishes dedicated mining ESG business unit

Datamine says it has established a dedicated environment, social and governance (ESG) business unit focused on the specific needs of the mining industry.

The new ESG business unit will bring together existing technologies and services under the leadership of Chris Parry.

Dylan Webb, CEO of Datamine, said: “We’ve observed that our customers are increasingly interested in managing ESG and its component systems as part of a single scope, led by senior executives.

“By establishing a dedicated business unit for ESG, we can now work closely with our customers on transformation strategies across the ESG spectrum, drawing on our deep domain knowledge to ensure the solutions provided are tailored to the mining industry.

“We are excited to have a leader of Chris’s calibre engaging with our enterprise clients to deliver improvements in ESG performance.”

Parry said he was impressed with the breadth of technology Datamine already has addressing the ESG needs for the mining industry.

“I look forward to working with Datamine’s global customer base to develop comprehensive ESG strategies underpinned by proven technologies,” he added.

Some examples of Datamine’s ESG technology portfolio include:

  • Discover GIS solution for geochemical, water, erosion and vegetation modelling and management;
  • Strategic planning tools to optimise extraction plans with minimum rehandle and intelligent waste dump design;
  • Qmed for workforce health management, COVID testing and vaccine administration; and
  • Centric Mining Intelligence for real-time transparency and governance across multiple sites and systems, including ESG key performance indicator reporting.

Beyond its technology suite, Datamine’s Snowden advisory division recently developed an in-pit crushing and conveying mining strategy for a customer that saved over 1 Mt of carbon emissions and A$700 million ($499 million) in cost savings, according to Datamine.

Webb said Datamine will continue to expand its ESG technology suite by investing in R&D and acquiring complementary solutions.

“It’s satisfying to see real momentum and desire by industry participants to improve ESG performance,” he said. “The community is increasingly realising that mining is essential for a low carbon future, but there is more we can do to minimise our impact along the way.”

Metso Outotec gears up for next generation of mining IPCC applications

A significant product launch in the in-pit crushing and conveying (IPCC) space was announced in parallel with the headline-grabbing co-operation agreement signed by Metso Outotec and FAM GmbH in June.

On the same day the two companies shook hands on a global non-exclusive pact to deliver integrated end-to-end solutions for IPCC and tailings management plants in mining, Metso Outotec, in a separate announcement, highlighted its Foresight™ semi-mobile primary gyratory (SMPG) station.

The SMPG station, which features the Superior™ MKIII primary gyratory crusher and patented SmartStation technology for “optimal processing”, is arguably the piece of the IPCC puzzle Metso Outotec has been missing.

Lokotrack® crushing plants have a solid reputation but only have capacities up to 3,000 t/h – one of the larger installations being a Lokotrack L200 at the Altay Polimetally copper operation in Kazakhstan. Such capacities work for most fully mobile IPCC installations, which tend to come with the highest complexity and are, therefore, a rare proposition, but semi-mobile hard-rock installations normally call for a much higher throughput.

This is where the SMPG station, with a maximum 15,000 t/h throughput capacity when equipped with the Superior MKIII PG 60110 primary gyratory crusher, fits the bill.

This station, when equipped with SmartStation technology, allows automated material size control and reduced wear, downtime and plant height, according to the company. It is also advertised as offering an up to 30% higher capacity on the same crusher size and 70% reduced downtime with the Superior MKIII primary gyratory technology, plus up to 30% power savings with patented Energy Saving Idlers. Maintainability is also boosted through improved crusher access and plant area isolation.

The station was included as part of an integrated IPCC solution launch from Metso Outotec that consists of crushing, conveying and stacking equipment, combined with IPCC planning and lifecycle services.

Leif Berndt, Director, IPCC at Metso Outotec, acknowledged that the SMPG is the core addition to this refreshed IPCC portfolio, but believes the company has already displayed its IPCC expertise in “a number” of large capacity (20,000 t/h) crushing and conveying system deployments in iron ore and copper applications in South America. It also recently sold a Foresight SMPG equipped with a MKIII 60110 primary gyratory to Codelco for its Radomiro Tomic operation, in Chile.

“In terms of crushing and conveying, we have carried out these building blocks to the same large capacities as others that call themselves the incumbents in this market,” he told IM. “With the new and experienced planning team we have in our Düsseldorf facility, we now have the in-pit development around those solutions to prove this.”

He expanded on the topic when discussing the ability to address the higher capacity IPCC segment with the SMPG: “It is one thing to look at it from the instantaneous, hourly, or shift throughput perspective; it is another thing to look at it from the design of the whole system, the plant and the mine planning to come to the customer with a workable solution that will produce, over the year, the tonnes required.

“You then need to sustain those numbers by having the right planning, system and service to sustain the crusher’s performance.

“That is where the true success for the customer is.”

Berndt says the company has all this in its offering, asserting that Metso Outotec should be considered a leading market player in the IPCC sector.

“It is quite simple: we are the number one in large capacity primary gyratory crushers; we are also the number one in service,” he said. “That covers, with technology and services, two very important aspects for a successful IPCC operation.

“We now have a very experienced IPCC team in Düsseldorf, and we are leveraging the engineering and product development group in Sorocaba, Brazil, to be closer to the markets east of the Atlantic. With that, we have the right team for planning, engineering and project delivery, the right technologies and services driving availability and, hence, productivity.”

That is even before mentioning the tie-up with FAM, which will allow Metso Outotec to play a significant role in end-to-end solutions across the IPCC space thanks to the inclusion of FAM spreaders and crawler-mounted conveyor bridges for waste IPCC applications and dry stacking of tailings.

Such a collaboration shouldn’t surprise anyone in this space.

Metso Outotec has been open – and remains open – to partnering with other OEMs for IPCC systems, evidenced by an agreement with Komatsu that sees Komatsu sizers fitted on Lokotrack systems for soft-rock applications.

“Technologies that are delivering advancements in sustainability, productivity and maintainability that are complementary to our offering, which we don’t own ourselves, are always interesting to us,” Berndt said.

Ready at the right time

Metso Outotec appears to have got its ducks in a row at exactly the right time as, with a strong environmental tailwind behind it, the IPCC market is on the up.

The need to electrify operations and reduce reliance on fossil fuels in line with ambitious decarbonisation targets is leading more and more miners to considering an element of in-pit work at their operations.

Greenfield mines are working on tradeoffs in the study phase to pit conventional truck and shovel against the use of more conveyors and in-pit crushing equipment, while brownfield operations are getting the mine models out again to see if an element of the operation can be reconfigured to make the most of fixed, semi-mobile or fully-mobile IPCC systems.

Berndt said many clients decide to go for modularised, configurable and semi-mobile solutions for ease of construction and assembly away from the run-of-mine (ROM) pad to improve scheduling. Such a configuration could allow parallel development of, for instance, crusher pocket development and the ROM pad.

Also, when it comes to a greenfield project, the cost to “buy yourself the option of relocating the plant”, when compared with the capital associated with installing a stationary plant, is, on many occasions, “insignificant”, according to Berndt.

“As a result, customers decide to ‘buy’ that option and, when the pit develops in the future, relocate the plant,” he said. “That, in itself, is a strong driver in the IPCC market.”

The tie-up with FAM will allow Metso Outotec to play a significant role in end-to-end solutions across the IPCC space thanks to the inclusion of FAM spreaders and crawler-mounted conveyor bridges (pictured, courtesy of FAM) for waste IPCC applications and dry stacking of tailings

Adapting existing hard-rock operations designed for truck and shovel operations by incorporating large capacity semi-mobile IPCC systems with crushing plant locations inside the pit remains a complex task from a planning perspective, but Berndt has seen an increase in interest in this option too.

There are mine engineering professionals in the Metso Outotec Düsseldorf office that have specific experience of adapting operations for IPCC solutions, he said.

“However, that being said, we all know conveyors don’t have wheels, and the cost of deploying or redeploying these conveyors requires pit ramp developments or pit pushbacks earlier in the mine process and, hence, earlier cash-out on overburden compared to a truck shovel development.”

The economic tradeoff that has led to such developments is starting to change in favour of IPCC solutions.

“In the mine investment decision and methodology selection, the net present value impact of ‘early overburden’, or pulling forward the push-back phases in conical pits to advance ramps for conveyor access, was formerly only offset against the lower production cost, which drove the payback point to a 150-200 m vertical lift component level,” Berndt said. “Carbon credits for energy saved against early cash-out will shift this payback point upward, increasing demand for IPCC solutions.”

Which is why Metso Outotec’s reinvigorated IPCC pursuit is considered timely.

More and more mining companies are becoming comfortable with carbon accounting and factoring it into project studies – whether these studies are distributed internally or externally. They are cognisant of the fact it may be a voluntary addition in the Excel spreadsheet formula today, but, in the years ahead, it will become a requirement of doing business.

“Metso Outotec, for example, has sustainability targets included in its recent renewal of a financial instrument,” Berndt said. “Access to funding and the cost, thereof, will increasingly depend exactly on that.”

Yet, this doesn’t spell the end of truck and shovel in the IPCC mining operations Metso Outotec is likely to serve, according to Berndt.

He sees an electrified future where the two elements will play happily together in the pit.

“You need the flexibility of trucks, whether that be from a hydrogen-, battery- or trolley-powered source at some point in time, to allow for the required selectivity and blending in the pit,” he said. “Given that the deployment of conveyors is limited by very short phases and the space/geometry of a typical hard-rock mine, it is not simply a convey or truck situation; it is a matter of using truck and convey to find the best interface.

“Obviously, the more you can take out of the vertical lift component by conveyors, the better, but, in the context of a majority horizontal haul, trucks are likely to be a lot more efficient.

“The developments now happening are the truck interfacing or delivering onto the conveyors in the pit and the ability to make that a more flexible process.”

Armed with Lokotrack solutions for a fully mobile IPCC solution, its family of FIT™ and Foresight™ modular crushing stations, the new SMPG, and a strong planning, engineering and service offering, Metso Outotec says it has all the necessary elements to deliver the mining sector’s next generation of IPCC systems.

Miners need flexible solutions to meet decarbonisation goals, Worley’s Russell says

The unique challenges the mining industry will face over its 30-year journey to decarbonisation are still being unpacked as it decides how to use enabling technologies and solutions, according to Nicholas Russell, Senior Mechanical & Mining Engineer at Worley.

“The journey to net-zero requires flexibility,” he said. “And we need to incorporate that flexibility from the very beginning.”

This, according to Russell, has seen an increased focus on collaborative solutions across the mining value chain, including the re-emergence of 70-year-old technology.

In-pit crushing and conveying (IPCC) works by crushing ore and waste material in an open-pit and using conveyors to transport the material to the process plant and waste dumps respectively.

While IPCC is not new, miners often associate it with rigid, inflexible mine plans that struggle to meet changing market demands, he said. “However, an IPCC system is no longer just a fixed asset. Flexibility and sustainability in operations is possible through design innovation, tailored equipment specification and automation.”

One of the new ways that IPCC can be implemented is by using a combination of relocatable and mobile conveyors in tandem with a mobile, truckless system. This sees a shovel dumps material into a moveable sizing rig that loads the automated conveyor fleet.

“Much like irrigation sprinkler machines, the system operates in parallel, or pivot, and a combination of different length hoses and pipes connect it back to a fixed point, which in this case is the process plant,” Russell said. “By increasing the reach of the system, multiple combinations of bench level, mine direction and pass widths can be considered and optimised.”

In one study, an overburden truck fleet that moved material from the mine face to the top of the in-pit dump was replaced with an IPCC system. The haulage energy was reduced by 63% and 3.5 Olympic swimming pools of diesel each year could be replaced with renewables for each shovel swapped over, according to Russell.

Providing flexibility for minimum viable projects

Alternatively, as the mine face moves, a relocatable IPCC system can move with it.

“Trucks powered by renewables complete small distances to a crusher which is moved periodically, with conveyors used for the rest of the journey to the plant,” Russell explained. “While both options give the flexibility to change mining locations, this option provides the energy efficiency and cost-effectiveness of conveyors while benefiting from the flexibility of a truck system.”

Flexibility is especially useful for miners establishing sites with “minimum viable capital”, according to Russell.

“Miners can start with a small truck fleet and minimum fixed plant, relocating the crusher and conveyor as and when required,” he explained. “This is a key advantage because it helps achieve project specific goals through different mine sequences to enhance an operation’s sustainability.”

Powering mines with renewable energy

Powered by electricity ‘from the grid’, IPCC can be an energy efficient option for miners. It gives miners the flexibility to choose renewables to power their site, including the energy used for the mass material movement from the mine face to the process plant and waste dump.

Worley and its consulting business, Advisian, has helped a number of mining companies assess and develop green energy supply partnerships, Russell explained.

This has included the analysis, assessment and guided procurement of Gold Fields’ Agnew Hybrid Renewable Energy Microgrid, which included 18 MW wind, 4 MW solar, 13 MW/4 MWh battery and 21 MW gas/diesel. As the largest hybrid renewable energy microgrid in Australia, it has the capacity to provide the mine with up to 85% renewable energy, with reliability in excess of 99.99%, Worley said.

Enhancing an IPCC system with bulk ore sorting technology

Nicholas Russell, Senior Mechanical & Mining Engineer at Worley

“As miners seek to get more from less, IPCC can be enhanced with ore sorting mineral sensing technology supplied by NextOre,” Russell said.

NextOre, a joint venture between the CSIRO, RFC Ambrian and Worley, is a bulk ore sorting technology that allows miners to sort and evaluate ore at high capacity, maximising recovery and delivering higher grade and lower tonnage mill feed, he explained.

“It can be easily retrofitted to IPCC conveyors, and measure everything on the belt,” he added. “The option also exists to increase grade while maintaining throughput on existing systems, maximising metal recovery through the entire system assuming upstream and downstream facilities can be de-bottlenecked.”

By improving sorting efficiency, and processing a better material grade, water and electricity consumption per tonne of ore mined is reduced, while the data from the sorting process can be used to learn more about what is coming out of the ground as it’s mined, with assumptions verified in real time.

IPCC in action

One of the world’s largest iron ore mines in Brazil, S11D (pictured, photo courtesy of Vale), is a notable example of how new IPCC technology is enhancing sustainability and protecting people and the environment.

For this project, Worley proposed a truckless mine – “the first of its kind”, Russell said.

The system uses mobile crushers and conveyor belts to replace traditional trucks, consequently reducing diesel consumption by approximately 70%, according to mine owner Vale. The system also allows the miner to process waste in existing industrial areas, moving it away from environmentally sensitive ones to further reduce the project’s environmental impact.

“In designing the project, the team’s biggest challenge was not only rethinking the mine plan and how the technology could be used on the site, but also re-evaluating the role people play in executing the concept,” Russell said. “It’s critical to re-educate technicians and engineers to equip them with the skills needed to work with these technologies safely.”

Russell believes technologies like IPCC will help miners meet their decarbonisation commitments, however no individual technology can solve the challenge.

“To focus solely on the benefits of the equipment and disregard the mine demands is a short-term solution to a long-term challenge,” he said. “If miners are to meet sustainability goals, they need flexibility, collaboration and a holistic approach to implementing new technology that starts at the mine plan.”

Nick Russell is due to speak at IM Event’s IPCC 2022 event in Mexico, on April 28-29, 2022, presenting a paper titled: ‘Fully mobile IPCC/truckless mining: lessons learnt’. Click here for more information on the event.

Metso Outotec wins major IPCC order from Codelco’s Radomiro Tomic mine

Metso Outotec says it has signed an agreement with Codelco in Chile to design and supply a Foresight™ semi-mobile primary gyratory (SMPG) crushing plant for Codelco’s Radomiro Tomic operation.

Equipped with a Superior™ MKIII 60-110 primary gyratory crusher, apron feeder discharge and dust collection, the Foresight™ SMPG meets the highest demands in productivity and sustainability, the company says. It is part of Metso Outotec’s in-pit crush and convey solutions (IPCC) portfolio.

Metso Outotec launched the SMPG in June alongside this IPCC offering and the announcement of a plan to cooperate with FAM on end-to-end solutions for IPCC and tailings management plants to the mining industry.

Back in March, Codelco was granted permission to prolong the life of the existing Phase I hydrometallurgical plant and sulphide mining operations at Radomiro Tomic until 2030. The original project considered the end of the operations associated with this stage of the project in 2022, however, thanks to the incorporation of new mining resources, it will be possible to extend it for another seven years from 2023.

Codelco said at this point that the exploitation of these resources requires the relocation of the current primary crushing of oxides and sulphides, which will require additional investments.

Metso Outotec said the value of the recent order is not disclosed, but it has been booked in the Minerals business September quarter orders received.

Markku Teräsvasara, President, Minerals, said: “We have extended our Planet Positive offering in June of this year, launching our IPCC solutions, combining the right team, technology and services to redefine productivity in this space. We highly appreciate Codelco’s continued trust in us to deliver significant crush and convey infrastructure to meet Codelco’s demanding operational and sustainability goals.”

Eduardo Nilo, President, South America Market Area, added: “We are honoured Codelco has chosen us to deliver this significant project in Radomiro Tomic and extend the fleet of Superior primary gyratory crushers at that site. With more than 1,300 employees and integrated fabrication of wear materials in Chile, we service our fleet of crushers holistically
and look forward to supporting this plant as well.”

Metso Outotec’s integrated modular in-pit crush and convey solutions consist of crushing, conveying and stacking equipment combined with IPCC planning and life cycle services. The offering is designed to ensure the highest productivity, energy efficiency, and maintainability, it says.

Metso Outotec IPCC solutions, with their improved energy efficiency, are part of the company’s Planet Positive portfolio. IPCC operations also reduce haulage related energy consumption and CO2 emissions.

FLSmidth looks for sustainable gains with thyssenkrupp mining buy

The subtleties behind FLSmidth’s acquisition of thyssenkrupp’s mining business appear to have got lost within the financial community.

The company’s Denmark-listed shares, since announcing the transaction in late July, lost 16% of their value to August 20.

This downward move is hardly surprising when focusing on pure financials: FLSmidth is looking to acquire a company for an enterprise value of $325 million that is only expected to return to profitability two years after financial close.

Yet, this narrow train of thought discounts the well-timed strategy behind the move.

A combination of the two companies will undoubtedly create a leading global mining technology provider with operations from pit to plant. It will also see FLSmidth re-geared towards a mining sector on the up at a time when the cement business it serves is exhibiting flattish demand.

While this won’t be lost on analysts, most of them will only be able to factor in short-term profitability projections into their financial models, meaning, as far as they’re concerned, FLSmidth will be weighed down by the transaction until 2024.

Yet, for FLSmidth and mining, 2024 is practically ‘just around the corner’.

In FLSmidth’s recently released June quarter results it registered an order backlog of DKK16.7 billion ($2.6 billion), the majority of which was associated with mining orders. Of the backlog amount attributable to the mining sector, 16% would not be realised until 2023 and beyond.

This could mean many of the orders FLSmidth registered in the most recent June quarter will only be realised (read: delivered) in 2024, the year thyssenkrupp’s mining business is expected to be back in the black.

This is just one of the subtleties that may have got lost by shareholders fixated on the short term.

The second is how the transaction sets the company up as a mining sustainability leader at a time when the industry is calling out for one.

At the top end of the mining industry, the ability to decarbonise operations is becoming as – if not more – important as returning cash to shareholders. Every tonne of copper extracted and processed, and every ounce of gold mined and refined is likely to come with an associated carbon content/price in future years. The battery materials supply chain tied to the likes of lithium, cobalt and nickel will come under even more scrutiny.

Blockchain-type traceability platforms will mean investors and any interested party can interrogate where the raw materials came from and how they were produced.

These same miners will also be judged on how they use water, with freshwater use being rationalised in many regions where such resources are scarce.

FLSmidth, should the acquisition complete next year, is arming itself to compete in this brave new sustainable world.

The company started this journey all the way back in November 2019 when it announced its MissionZero program at its Capital Markets Day in Copenhagen.

Central to MissionZero is FLSmidth’s focus on enabling its customers in cement and mining to move towards zero emissions operations in 2030.

The OEM planned to do this by leveraging the development of digital and innovative solutions tied to sustainable productivity, offering its customers in the mining sector the technological solutions to manage zero emissions mining processes by 2030 – with a specific focus on water management.

For the latter, dry-stack tailings was the order of the day, with FLSmidth’s EcoTails® solution expected to reduce water costs, tailings dam risks and minimise environmental footprint. The development of the largest filter press plate ever built, the 5 m x 3 m AFP, was a signal of just how confident FLSmidth was on this emerging market trend becoming fully embedded across the globe.

Digital products such as SAGwise™, SmartCyclone™, BulkExpert™ and Advanced Process Control would, in the meantime, allow miners to become that more efficient with every resource (water, energy, etc) they used, again, improving their sustainability credentials.

Close to two years after making the MissionZero declaration, Thomas Schulz, CEO of FLSmidth, says the company has been seeing the program’s effects come through in its order book.

“Actually, this has been translated in orders for a few years already,” he told IM.

“When we look into sustainability, we define it as making productivity improvements. If you don’t adopt these sustainability solutions, you effectively have to pay more to keep operating at the same levels, or you have to stop operating – there is a productivity element to it, and quite a big one.

“For us, as a lifecycle provider, it is important that we offer to our customers at any point in time and any point of our offering, the right solution to make more money. That can be with dry-stacked tailings, tailings management, IPCC (in-pit crushing and conveying) systems, electrification of the pit, reducing emissions or dust, etc.”

Many of these solutions will enable companies to produce the same amount of product, or more, with the same input costs and energy draw, according to Schulz.

Coping with further restrictions on the industry’s access to freshwater will require more than step-change initiatives, and that is why the company is working on how its equipment can use “different types of water” and technologies that use less freshwater to ensure operations can abide by incoming legislation.

The company has been working on providing these zero-emission and resource-efficient solutions since 2019 to enable its customers to become sustainable operators by 2030.

“For many people, that sounds very long,” Schulz said. “In the mining industry, it’s not.”

Factor in the two-to-three years to build a pilot plant to prove such technology, two-to-three years to get a full-scale plant approved and the associated construction time, and a decade has passed.
Sustainability represents the ‘long game’ for mining OEMs, and technology is the key to achieving that sustainability, Schulz said.

Which brings us back to the thyssenkrupp mining business acquisition.

One of the big pillars

FLSmidth, in adding thyssenkrupp mining to its portfolio, is providing a whole host of decarbonised options for its mining customers to consider in their own sustainability drive.

It is adding mine planning expertise to its portfolio, ensuring that the IPCC and continuous surface mining technologies it puts forward are optimised for the operation at hand. These technologies are further complemented by semi-continuous and mobile crushing options from thyssenkrupp mining, adapted to the pit profile at hand.

Heavy-duty overland conveyors from thyssenkrupp mining complement other bulk handling solutions FLSmidth might be providing at stockyards or ports to reduce truck haulage and shift the transport dynamic to ‘green’ grid power.

“The culture in project service companies is you are the hero if you come to the table with the next big project,” Thomas Schulz says. “In product service companies, you are the hero if you come with the next big profit”

Then, when it comes to comminution, a crushing (including primary jaw crushers) and screening portfolio, plus smaller milling options and expertise in high pressure grinding rolls (HPGRs) through the globally renowned Polysius business, is bolted onto FLSmidth’s own crushing and grinding (including vertical roll milling technology) portfolio. This puts the combined offering up there with any global OEM around, while also providing the potential ‘dry grinding’ technologies the industry has been on the lookout for.

All these solutions come with sustainability benefits that can be felt throughout the mining value chain.

They also provide options and flexibility to an industry that cannot just suddenly retire a fleet of ultra-class haul trucks at a deep open-pit operation in favour of a fixed IPCC solution, or build a new process plant fitted with HPGRs to replace a typical SAG and ball mill grinding circuit.

Schulz said as much to IM.

“One of the big pillars of the whole acquisition lies in sustainability,” he said. “Normally, the process plants where we play big are all electrified, so if the energy resource coming into these plants is a green one, the process is already sustainable.

“When we look into the pit, in-pit crushing and transporting of material is where we can focus a lot.

“I’m not saying you can replace every truck, but some of the surface mines and the ones underground can be made significantly more continuous and sustainable from a transport perspective.

“thyssenkrupp is leading in that. They are quite big in the pit; we are quite big in the processing plant. Both, together, are complementary.

“If we can integrate the offering – and we will do – and make it more sustainable, that is a big step towards the 2030 MissionZero target.”

This increased spread of solutions will also provide FLSmidth with more opportunities to refine the entire flowsheet, providing further sustainability benefits to its customers.

“When we design solutions, or offer replacement equipment or a new process, we can now rely on expanded competences to look at what the best overall system for the entire flowsheet is,” Schulz said. “For instance, if we change the gyratory on a mine site and then look into the pit, we know how to size the equipment in the pit and the concentrator upstream.”

This increasing flowsheet focus must be complemented by an aftermarket approach that ensures the process remains efficient and sustainable throughout a product’s, solution’s or mine’s lifetime.

This was one of the obvious disparities between the two companies when the announcement was made in late July. It is also one of the biggest opportunities that comes with the planned transaction, according to FLSmidth.

Whereas capital business represented 37% of mining revenue in 2020 for FLSmidth, it was 66% of revenue for thyssenkrupp’s mining business. Services represented 63% and 34% of the two businesses’ 2020 revenue total, respectively.

Schulz has seen such a contrast – and opportunity – before, referencing his arrival at FLSmidth in 2013.

“When I came here to FLSmidth, it was actually quite similar,” he said. “I was at Sandvik for 16 years where the aftermarket was actually seen as the most important. They realised the importance of the customer relationship: the capital equipment sales team may meet the customer for a few hours per year, but the service technician has that interaction over weeks and months in terms of aftermarket.”

He also recognises the cultural shift needed to capture many of the profitable aftermarket dollars that the company is forecasting with the planned acquisition.

“The culture in project service companies is you are the hero if you come to the table with the next big project,” he said. “In product service companies, you are the hero if you come with the next big profit.

“You need both – we need profit, and our customers need profit to invest, while you need the projects to spur these aftermarket opportunities.

“We calculated what the aftermarket potential of the thyssenkrupp mining business is and understood it was not covered as they were all looking for the next big project, which we understand.

“But this is not what we will accept in the future. We have to have a strong aftermarket and strong customer link.”

Which all comes back to MissionZero.

“If you focus on MissionZero, then you invest there where you can impact MissionZero. Wherever you have aftermarket, you impact MissionZero. Where you don’t have aftermarket, you don’t impact MissionZero.”

At the same time, Schulz is not losing sight of the company’s end goal with all the business it coordinates in the mining sector.

“Whatever we do with the customer, they have to be more efficient, more productive and make more money.”

It just so happens that in doing this, the mining sector will become that much more sustainable.

Metso Outotec and FAM to collaborate on IPCC, tailings projects

Metso Outotec and FAM GmbH have signed a global non-exclusive co-operation agreement on the delivery of integrated end-to-end solutions for in-pit crush and convey (IPCC) and tailings management plants to the mining industry.

The combination of the companies’ leading expertise in their respective fields will allow the parties to form the market’s strongest offering for IPCC and tailings management plants, they said.

“Mine electrification, reduction in power and water consumption, as well as de-risking tailings disposal, are common goals for the mining industry and Metso Outotec to improve sustainability,” Metso Outotec said. “State-of-the-art IPCC and tailings management plants cater for these requirements.”

Markku Teräsvasara, President of the Minerals business area at Metso Outotec, said sustainability is a top priority for Metso Outotec.

“In addition to our investments to develop our IPCC and tailings management plant offering, we are pleased to be able to announce our cooperation with FAM,” he said. “This will allow us to meet our customers’ growing demand in such plants, where spreaders or conveyor bridges are required.”

Torsten Gerlach, CEO of FAM, added: “FAM’s leading technology in dry tail stacking systems and spreaders ties well in with Metso Outotec’s hard-rock crushing and minerals processing portfolio. Where end-to-end systems are required, we are glad teaming up with a strong partner.”

Piedmont looks at IPCC, Metso Outotec alkaline pressure leach for lithium project

Piedmont Lithium’s plan to build out an integrated lithium hydroxide business from a base in North Carolina, USA, has advanced with the release of a scoping study that, it says, confirms that Carolina Lithium will be one of the world’s largest and lowest-cost producers of lithium hydroxide with a “superior” sustainability footprint.

Piedmont Carolina Lithium contemplates a single, integrated site, comprising quarrying, spodumene concentration, by-products processing, and spodumene conversion to lithium hydroxide at its site in Gaston County. There are currently no such integrated sites operating anywhere in the world, with the company saying the economic and environmental advantages of this strategy are compelling.

The latest study outlined a production target of around 4.96 Mt of 6% Li2O spodumene concentrate (SC6), averaging approximately 248,000 t/y of SC6 over the 20-year mine life. This equates to an average of 1.95 Mt/y of ore processed, totalling some 37.4 Mt of run-of-mine ore at an average grade of 1.09% Li2O (undiluted) over the 20-year mine life.

Of the total production target of 4.96 Mt of SC6, some 1.19 Mt will be sold to third parties during the operational life and approximately 3.77 Mt will be supplied to Piedmont’s chemical plant operations for conversion into lithium hydroxide. This results in a total production target of about 582,000 t of lithium hydroxide, averaging approximately 29,095 t/y of lithium hydroxide over 20 years, the company said. The study also assumes production targets of 4.83 Mt of quartz concentrate, 7.51 Mt of feldspar concentrate, and 1.34 Mt of mica concentrate over the life of operations.

Piedmont envisages a total initial capital cost of $838.6 million for the project and an after-tax net present value (8% discount) of $1.92 billion.

While still very much preliminary, the flowsheet and mining process for this planned operation is of interest to any lithium developer looking for a ‘sustainable’ mining footprint.

The company currently envisages using a Metso Outotec alkaline pressure leach process as part of its plan. This will reduce emissions, eliminate sulphuric acid roasting and reduce solid waste, it said.

At the same time, in-pit crushing and conveyor systems are on the agenda, eliminating mining trucks in the study to reduce fossil fuel consumption.

Piedmont has also been working with a solar developer to build and operate a solar farm on Piedmont property capable of producing electricity to supply up to 100% of Piedmont needs.

The company will also co-locate all operations on the same proposed site in Gaston County to minimise any transit and allow unused by-product streams to be repurposed for site redevelopment, it said. This adds up, Piedmont says, to highly efficient land and water use compared with South American lithium brine production.

Keith D Phillips, President and Chief Executive Officer of Piedmont, said: “We are exceedingly pleased with the results of our updated scoping study. The economics of our project continue to impress, but I am particularly proud of the project’s sustainability profile.

“As we move forward to complete a definitive feasibility study for Carolina Lithium later in 2021, Piedmont has engaged Evercore and JPMorgan as financial advisors to evaluate potential strategic partnering and financing options for its North Carolina project. Given the project’s unique position as the only American spodumene project, with world-class scale, economics, and sustainability, we expect strategic interest to be robust.

BHP weighs trolley assist and IPCC as part of decarbonisation efforts

BHP has provided an update on its progress on climate action, new climate commitments and how it integrates climate change into corporate strategy and portfolio decisions in a new report.

The company’s climate change approach focuses on reducing operational greenhouse gas emissions, investing in low emissions technologies, promoting product stewardship, managing climate-related risk and opportunity, and partnering with others to enhance the global policy and market response, it says.

“BHP supports the aim of the Paris Agreement to limit global warming to well below 2°C above pre-industrial levels, and pursue efforts to limit warming to 1.5°C,” the company clarified.

It explained: “BHP has been active in addressing climate risks for more than two decades, and has already established its long-term goal of achieving net zero operational (Scope 1 and 2) emissions by 2050 and its short-term target of maintaining operational emissions at or below financial year (FY) 2017 levels by FY2022, using carbon offsets as required.”

In the past year, BHP has made progress on this aim, announcing that the Escondida and Spence copper mines in Chile will move to 100% renewable energy by the mid-2020s, and, last week, awarding new renewable energy contracts for its Queensland coal assets, and the world’s first LNG-fuelled Newcastlemax bulk carrier tender.

BHP’s climate change briefing and 2020 climate change report outline how the company will accelerate its own actions and help others to do the same, it said. Today’s update sets out:

  • A medium-term target to reduce operational greenhouse gas emissions by at least 30% from adjusted FY2020 levels by FY2030;
  • Scope 3 actions to contribute to decarbonisation in its value chain. This includes supporting the steelmaking industry to develop technologies and pathways capable of 30% emissions intensity reduction with widespread adoption expected post-2030 and, in terms of transportation, supporting emissions intensity reduction of 40% in BHP-chartered shipping of products;
  • Strengthened linking of executive remuneration to delivery of BHP’s climate plan; and
  • Insight into the performance of BHP’s portfolio in a transition to a 1.5°C scenario.

The report also outlined some examples of emission reduction projects the miner is considering, which will be weighed as part of the maintenance capital category of its capital allocation framework. This includes solar power installations; alternative material movement technologies such as overland conveyors and in-pit crush and convey solutions; and trolley assist to displace diesel for haul trucks.

The company expanded on this in its report: “The path to electrification of mining equipment will likely include solutions such as trolley assist, in-pit crush and convey, overland conveyors and battery solutions.

“Diesel displacement represents a higher risk, higher capital step towards decarbonisation, so a phased approach to execution is proposed with particular emphasis on Minerals Americas-operated assets that are further advanced on the decarbonisation journey. Taking a transitional approach to electrification provides flexibility to allow for the potential for rapid development of emerging technologies and to resolve the complexities of integrating these technologies into existing operations.

“During FY2021, we will seek to collaborate further with International Council on Mining and Metals members, industry and original equipment manufacturers to progress research and development to reduce costs and assess any potential impacts from electrified mining equipment solutions to replace current diesel options.”

BHP Chief Executive Officer, Mike Henry, said of the report: “I’m pleased today to show how we are accelerating our own actions and helping others to do the same in addressing climate change. We see ourselves as accountable to take action. We recognise that our investors, our people and the communities and nations who host our operations or buy our products have increasing expectations of us – and are responsive to these.

“Our approach to climate change is defined by a number of key requirements. Our actions must be of substance. They must be real, tangible actions to drive emissions down. We must focus on what we can control inside our business, and work with others to help them reduce emissions from the things that they control. To create long-term value and returns over generations, we must continue to generate value and returns within the strong portfolio we have today, while shaping our portfolio over time to benefit from the megatrends playing out in the world including decarbonisation and electrification.

“Our portfolio is well positioned to support the transition to a lower carbon world aligned with the Paris Agreement. Our commodities are essential for global economic growth and the world’s ability to transition to and thrive in a low carbon future. Climate change action makes good economic sense for BHP and enables us to create further value.”
