The next step in the integration of SP Mining – the mining-related business of Schenck Process acquired by global, high-tech engineering group Sandvik – will see SP mining entities change their names to reflect their new ownership.

On October 1, Schenck Process Australia Pty Limited, which became a wholly-owned subsidiary of Sandvik in November last year, will become Sandvik Rock Processing Australia Pty Limited. The Australian entity is the largest part of SP Mining’s global business, employing around 450 industry professionals.

Since the acquisition, Sandvik has been focused on bringing together its expertise in crushing with the screening, feeding, weighing and loading know-how of Schenck Process Mining.

According to the company’s President Asia Pacific, Terese Withington, this move is part of an integration process that will eventually see SP Mining become a seamless part of the Sandvik organisation.

“In Australia, we are bringing together our sales and back-office teams with those of Sandvik Rock Processing Solutions to allow our customers to access our combined expertise in crushing, screening, feeding, weighing and loading,” she said. “Together we aim to deliver even better digitalisation, sustainability and productivity solutions to our industry.

“The end goal of our integration is to allow our customers to place combined crushing, screening, feeding, weighing and loading orders with our new legal entity.”

Withington says the scale of Sandvik’s operations and commercial reach will help to accelerate the combined innovation portfolio of Sandvik Rock Processing Solutions and SP Mining.

She concluded: “We look forward to continuing to service the business needs of our customers and remain fully focused on the delivery of high-quality equipment, consumables, OEM spare parts and services to help them achieve their business objectives.”

Capital to carry out earthmoving and crushing services for FMG-tied Ivindo Iron in Gabon

Capital has announced the award of a new mining services contract with Ivindo Iron SA, majority-owned by Fortescue, at its namesake project in Gabon.

The earthmoving and crushing services contract has been announced at the same time as the company has extended its revolving credit facility.

Ivindo is in the northeast of Gabon and is one of the world’s largest undeveloped, high-grade haematite iron ore deposits with the potential to become a globally significant iron ore mine, according to Ivindo Iron, which is the operating entity for the Belinga project and a company that Fortescue has a 72% indirect interest in.

Earlier this year, Fortescue, through Ivindo Iron SA, signed the Mining Convention for the Belinga iron ore project in Gabon with the Gabonese Republic, paving the way for first mining to begin in the second half of 2023. Belinga is part of the wider Ivindo project.

The Capital contract has a term of up to five years and will generate approximately $30 million of revenue per year once fully operational, the London-listed company says. It involves both earthmoving and crushing services. Capital says it will use existing equipment and is in the process of purchasing circa-$15 million of additional equipment to service the contract.

Capital has already begun mobilising equipment to the site. This mining and crushing services contract is in addition to the three-year reverse circulation and diamond drilling services contract with Ivindo, announced earlier this year, where drilling recently commenced.

Peter Stokes, Chief Executive Officer, said: “We are thrilled to have been awarded the mining and crushing services contract at Ivindo. This is our second significant mining services contract and continues our strategy to diversify our revenue stream through an expanded service offering. We look forward to working closely with Ivindo Iron to expand our relationship from drilling services to mining and crushing services and ensure a rapid ramp up on this world-class deposit.”

MetsoOutotec-testing

Metso Outotec on the need for holistic testing

The Metso Outotec global network of testing, research and product development facilities covers the whole process flowsheet from comminution through separation, to filtration, refining and pyrometallurgical/hydrometallurgical processing.

It has centres all over the globe – in Australia, Brazil, Chile, Germany, Finland, Peru, USA and more – able to, the company says, offer extensive expertise and circuit simulation to a wide range of industries.

Metso Outotec’s research and testing services include evaluation of ore types, mineralogical characterisation, feed material testing, sampling, materials selection, analytical chemistry and flowsheet development.

To get a flavour of this extensive research and testing portfolio, IM spoke to Alan Boylston, Director, Process Engineering at Metso Outotec, and Rodrigo Grau, Technology Director – Minerals Processing at Metso Outotec, about the capabilities of two of the company’s facilities – York (USA) and Pori (Finland), respectively, while also touching on Metso Outotec’s global testing and research capabilities.

In 2022, the company announced a consolidation of its minerals testing services in USA into a single 5,500 sq.m facility in York able to eventually cover the full minerals value chain and support the mining industry worldwide. Pori, meanwhile, focuses on mineral technology, hydrometallurgical processes development, pyrometallurgy and ferroalloys technology and material technology. In other words, the company conducts laboratory and pilot test work, flowsheet development as well as validation and development of new technologies for the industry.

IM: Will the York facility now be seen as your ‘testing centre of excellence’?

AB: The York facility is a centre of excellence for testing, but we have many of these within the company. Our global presence, the knowledge and our expertise at each of these locations is one of the factors that sets us apart.

Each of our locations is a centre for excellence in its own field. Pori, for example, has extensive research capabilities, Sorocaba in Brazil focuses on comminution and beneficiation testing, while Lappeenranta Dewatering Technology Center concentrates on thickening and filtration. Each location is an integral part of our global testing offering. In addition to these, we have various facilities around the globe covering also aggregates and pyrometallurgical testing, research and development.

That being said, the effort we have made to expand the York Test Center gives us a much better advantage for research and testing in North America, compared to a few years ago. We can now do more pilot-scale testing, especially with equipment like our HRC™800e high pressure grinding roll (HPGR). We can also carry out pyrometallurgical testing, plus conduct magnetic separation tests. At some point in 2023, we also expect to add thickening and filtration testing to this remit. But this is a very high-level view of what we have to offer in the York location.

Metso Outotec has a global network of testing, research and product development locations

IM: Even with this consolidation in USA, are you expecting to collaborate with other global facilities when it comes to testing processes throughout the flowsheet?

AB: Yes, absolutely. For example, we have a project coming in right now where the sample was first in Tampere (Finland) for some crushing test work, before they split off a sample for us for grinding test work in York and then Pori is also receiving a sample for some broader mineralogy testing.

This speaks to why we are able to claim to have global capabilities. No matter the testing or research need, we are able to assist our customers to get the job done. This all goes towards one goal – the customer’s benefit.

IM: How do you see these testing capabilities interacting and benefitting from other modelling work you carry out in-house? For example, do you anticipate using these facilities and the likes of the Geminex digital twin in unison to offer clients physical and digital representations of flowsheet options?

RG: Modelling is very important for us. In each project we work on, modelling and simulation are at the heart. Here in Pori, we carry out flowsheet development and technology validation. One of the outputs of our work is to end with a simulation of an industrial plant. Going from that simulation into Geminex is just one more step we will be taking in the future.

AB: At the York lab, we are now moving to a SCADA-based system to run everything: when a sample comes in, it gets tagged and identified and we then automatically know what test to run. We have tablets to, for instance, setup all the parameters of a test for an HRC 800e. We can start and stop the test on that tablet and see the real-time information coming in as the test is being carried out. That data is also being stored for future use.

We’re undergoing a program right now to build out a database function where all the post processing of this data goes on in the background and can then be seamlessly integrated into things like our HRC simulation software. We are building the backbone to carry out that real-time digital twinning.

IM: Do you anticipate your global testing capabilities to lead to a higher uptake of Planet Positive solutions?

AB: With our customers having a huge focus on sustainability, I do. As an example, since we have had the pilot-scale HRC 800e available for testing, it has been fully booked. In 2023, we are preparing for a test plan where we could take the HRC product and go directly into a pilot Vertimill. Those are two Planet Positive approaches we are putting together in a single test plant to show how far we can push energy efficiency and media consumption reduction.

RG: I would definitely agree with Alan. And to add to that – for example at Pori, we do a lot of hydrometallurgical testing and piloting, and that is only increasing with the rising demand for lithium and other battery minerals. And our customers are really looking at how our equipment is reducing their carbon footprint and other sustainability benefits.

You will hear us say it time and time again, but this is definitely a trend that we are seeing at all of our facilities.

Metso Outotec testing and research capabilities cover the entire flowsheet – from comminution through the entire operation to pyrometallurgical/hydrometallurgical processing

IM: Will these expanded testing facilities also benefit your equipment and process R&D work?

AB: I think so. We built this lab to not just be a materials testing facility, but also a research hub, especially for grinding, but also for any other Metso Outotec business area needs. There is definitely a huge opportunity out there for us!

RG: And this rings true around the globe at all our facilities. For example, in separation, we have been testing the Concorde Cell™ flotation technology in Pori for a long time. And that is how we’ve approached development of a lot of our other innovations that go to market.

IM: How would you say industry testing requirements have changed over, say, the last five years?

AB: From our perspective, I am seeing more comprehensive test programs come through.

Instead of, say, one certain test, it is an entire test program with specific timings around evaluations and the ability to develop the flowsheet through the testing required. There is more collaborative designing of the flowsheet taking place through testing than there was five or 10 years ago.

RG: It is certainly more comprehensive now than it previously was.

For example, we carry out early engagement with our customers in Pori and start developing a flowsheet and evaluating the ore types.

The amount of material that is tested nowadays is much bigger than it was before. Obviously, it is not just limited to this example, because, as Alan mentioned before, we’ve got this connection between all our facilities to ensure our customers get exactly what they need from their testing program.

Also, our customers think about different drivers in the process very carefully and want that reflected in the test work. That could be more evaluation on the water they consume. They also look at the energy expended, on top of the expected recoveries and metal grades.

There is more emphasis on sustainability, even at these early stages, in addition to looking at how the ore types may change over time and what impact this will have on the processing requirements.

This is where our extensive simulation and modelling capabilities are leveraged for the biggest impact.

IM: Anything else to add?

RG: Pori and York are but a fraction of the expertise of the wider Metso Outotec research and testing portfolio; one that continues to expand in line with customer requirements. We don’t just cover mining, either – like our equipment offering, we provide research and testing services for the whole flowsheet.

And we are continually improving our capabilities in this space for our customers. So, stay tuned for the future and where we can take research and testing!

Miners continue cost control focus amid demand uptick, BME’s Hennecke says

Explosives and blasting, Mining events, Mining services, , , , , , , , , , ,

As BME gears up to showcase its explosives and blasting offering to a Mining Indaba crowd in Cape Town, South Africa, that is encouraged by the global energy sector’s appetite for minerals, the company’s Managing Director warns that the mining industry is still focused on reducing its cost base.

The demand for minerals – many of which can be sourced in Africa – is good news for the future of mining, and will no doubt be an important focus at this year’s Investing in Mining Indaba, which runs from February 6-9.

However, the pressure on mines is still all about low-cost production, Ralf Hennecke, Managing Director of Omnia Group company BME, warns. This year, BME will be exhibiting at the event to showcase its mining and explosive solutions, including its flagship AXXIS Titanium™ electronic initiation system.

Hennecke is bullish about the positive impact of the energy revolution on mining, as there is widespread expectation that volumes of battery-related commodities will need to ramp up considerably. Efforts to decarbonise the world economy are relying on energy technologies that are mineral-intensive, he explained.

“The average amount of minerals needed for a new unit of power generation capacity will grow by 50%, according to predictions by the International Energy Agency,” he said. “This is because solar photovoltaic plants, wind farms and electric vehicles generally require more minerals to build than their fossil fuel-based counterparts.”

The typical electric car, for instance, requires six times the mineral inputs of a conventional car, and a wind plant requires nine times more mineral resources than a gas-fired plant. This quickly translates into considerable demand growth in certain minerals.

“In terms of lithium, the largest consumers are now electric vehicles and battery storage applications,” he said. “It is expected that these applications will also be the largest consumer of nickel within less than 20 years.”

While this is good news for Africa, where many battery minerals will be sourced, the continent’s mining sector will always need to be globally competitive, BME says. This means efficiency across the mining value chain, rooted in on-mine productivity and safety.

“As an early-stage activity in the mining cycle, BME recognises the importance of blast design and execution in laying the groundwork for optimal operations,” Hennecke said. “Our technology developments including AXXIS™ and other digital innovations allow quality blasting that raises productivity in energy-intensive phases such as loading, hauling, crushing and milling.”

Only by optimising efficiencies can mines achieve a place in the lowest cost quartile of producers, which in turn enhances their commercial viability and makes them less reliant on commodity price cycles, BME says.

“Given the cyclical nature of the mining industry, Africa’s mineral producers can build a long-term future for the sector by remaining sustainable even through the dips in the cycle,” Hennecke said. “There is a depth of experience and technologies, developed right here on the continent, that can help put them in that advantageous position.”

The AXXIS Titanium system being showcased at Mining Indaba has been trialled and tested in various global mining destinations and conditions.

Pilot Crushtec talks up DoppiaTrac DR400 fully mobile double-roll crusher

Coal technology, Comminution of minerals, Mineral processing, Mining equipment, Mining services, , , , , , ,

Pilot Crushtec says Africa’s only locally manufactured, fully mobile double-roll crusher, the DoppiaTrac DR400, continues to perform well in the field of mobile coal crushing.

The DoppiaTrac DR400 now has a decade of success in the field, according to the company, achieving production rates of 300-400 t/h.

“We designed the DR400 from the ground up to give us the flexibility to produce a truly great crushing solution,” Jorge Abelho, Director, Technical Support at Pilot Crushtec, said. “It has proved itself through its combination of throughput, reliability and economy.”

The machine’s ability to reduce the generation of fines is thanks to the double-roll crusher. While a horizontal shaft impact crusher creates more coal fines due to impact energy, the double-roll crusher forces material through a constant gap, according to the company.

Pilot Crushtec Sales Engineer, Ben Armitage, said: “The crusher uses just enough energy to break the material down to the size of the gap. The DR400 generates less than 5% of 0-6 mm fines, compared to around 12% created by impact crushers – depending on coal hardness and crushing ratios.”

The DR400 boasts a large hopper that is readily fed by loaders or excavators. To increase the average production rate, the unit can be interlocked as part of a crushing train. Connected with a Metso LT106 jaw crusher, the two units can communicate to synchronise the feed rate. This optimises throughput by automatically adjusting the rate of material moving between the machines. The on-board hydraulic rock breaker on the Metso LT106 also allows oversize material to be quickly broken, avoiding blockages and preventing downtime, according to the company.

Crushing efficiency is enhanced by feeding material into the crushing chamber at exactly the same speed that the drums are spinning, Pilot Crushtec explains. This minimises attrition and friction, even at high throughput rates.

Armitage said: “The safety features on the DR400 ensure that it is compliant with demanding safety protocols applied by mining companies. These include full guarding around all moving parts, access points, nip points and crushing points – as well as pull cords and emergency stops to quickly isolate the unit when necessary.”

He explained that the efficient Volvo engine delivers the lowest kW per tonne of any mobile double-roll crusher working in the coal sector. Depending on coal characteristics, the engine’s 160 kW output can convert to a ratio of just 0.4 kW/t.

“The fuel consumption is also a significant factor for operators, and this crusher can run on as little as 17 litres per hour,” Armitage says. “This is achieved with a hydraulic load sensing system and an optimised crusher chamber design, which reduce the power needed to crush the coal.”

The quality and simplicity of the DR400 is demonstrated by the fact that over 25 of these machines are currently in operation around South Africa – one of which exceeds 22,000 hours of operation. Pilot Crushtec says it supports the DR400 through its service levels, stock holding and after-market offerings.

Tungsten West cuts CAPEX with new Hemerdon feasibility study plan

Energy minerals, Mineral processing, Mineral project development, Mining services, , , , , , ,

An updated feasibility study on Tungsten West’s Hemerdon project in Devon, England, has brought with it a processing re-optimisation program that includes a complete redesign of the front-end crushing circuit at the mine, a process that, it says, will considerably reduce the capital expenditure associated with this development.

The new study outlined average annual production of 2,900 t of WO3 in concentrate and 310 t of tin in concentrate over a life of mine of 27 years, along with an average steady-state mining rate of 3.5 Mt/y.

The changes to the existing process flowsheet to be implemented at Hemerdon can be categorised into three areas, namely:

  • Front end upgrades – new crushing, screening and ore sorting circuit required for Phase 1 (average of 2.4 Mt/y of granite ore, years 1-2);
  • Existing minerals processing facility modifications – upgrades to existing plant to accommodate production requirements for Phase 1; and
  • Phase 2 (3.5 Mt/y of granite ore, year 3 onwards) crushing and process plant expansion – future upgrades to both crushing and processing plants required for increased production rates, envisaged from year three onwards.

The re-engineering has mainly reduced capital and operating expenses around reduced ore handling costs by the introduction of direct tipping at a newly sited run of mine pad, incorporating the introduction of new semi-mobile primary jaw and secondary cone crushers, new operating parameters for the ore sorting circuit, and, to a lesser extent, changes to the existing dense media separation and fine gravity dressing circuits.

The revised front-end design also includes a significant tactical advantage through the introduction of a secondary crushed ore stockpile ahead of the ore sorters, Tungsten West said. This provides up to circa-40 hours of redundancy capacity to the crushing circuit, thereby de-coupling the front end crushing circuit from the minerals processing facility (MPF) – minimising downtime and maximising availability of the concentrator circuit.

Tungsten West has maintained the ethos of the original feasibility study in continuing to engineer-out as many operational, mechanical, electrical or ESG issues associated with the previous operation as possible and to ensure MPF availability and operability remains a priority, it said.

Back in July, Tungsten West concluded a re-evaluation of the options for bringing the Hemerdon mine back into production, announcing a new development plan that would re-optimise the March 2021 Bankable Feasibility Study. The plan was developed in response to global crises in power and diesel prices and the general inflationary environment for construction materials faced by the company.

The new plan has resulted in a remaining capital expenditure, including EPCM fees, of £31.1 million ($38 million) as of October 1.

Mark Thompson, Executive Vice Chairman of Tungsten West, said: “The feasibility study provides solutions to the energy price challenges and will enable increased operating efficiencies at the project. Key highlights from this study include a revised ore delivery and waste mining strategy, a split-phase approach to operational ramp-up to the full design specification, a new primary and secondary crushing method and location, a re-optimisation of the operating strategy for the X-ray Transmission ore sorters, re-design and re-engineering of the feed preparation, ore sorter buildings and structures, and a re-evaluation of the operation of unit processes and expected recoveries.

“We are build-ready at Hemerdon and we look forward to continuing to work with our partners and stakeholders to bring Hemerdon back into production in the fourth (December) quarter of 2023.”

BEUMER Group and FAM ‘the right project partner for all challenges’, Hotz says

Bulk handling, Equipment maintenance, Mineral processing, Mining equipment, Mining mergers and acquisitions, Mining safety, Mining services, Water management, , , , , , , , , , , , , , ,

In June, BEUMER Group completed the acquisition of the FAM Group of Magdeburg, Germany, in the process, increasing its conveyor system and loading technology offering and becoming a significant player in the in-pit crushing and conveying (IPCC) space.

Close to six months after closing, IM put some questions to Stefan Hotz, Director Sales FAM Group, to find out how the integration of the two companies is going and how the transaction should strengthen the enlarged company’s market position in the minerals and mining sectors.

IM: Where – regionally – do you see the most opportunities in the mining sector for the integrated company to gain market share? South America has been a particularly strong market for FAM in the past; do you see this as a big opportunity for the integrated group?

SH: FAM – member of BEUMER Group – is one of the world’s leading full-range suppliers of bulk handling and processing systems. The customers come from more than 80 countries and the solutions are successfully in use everywhere. With BEUMER’s acquisition of the FAM Group, we were able to expand our portfolio to include bulk material handling, crushing technology as well as conveyor technology. Customers receive solutions from a single source with which they can work efficiently. In addition to engineering and project execution competences, FAM also brings the complete value chain, including after-sales service, to the BEUMER Group. This makes us a sought-after partner worldwide.

Of course, South America is a strong market, especially countries with iron ore and copper resources such as Brazil, Chile and Peru. For example, in Peru, the mining companies are transporting iron ore to the stockyards, which are often located at distances of several kilometres from the port. Callao Port, for example, is home to the most modern and largest ship loading terminal in the country. A reliable and safe connection for material transport is required, which at the same time ideally prevents the emission of particles into the atmosphere. Conveyors are the preferred solution here that can be individually adapted to the respective environmental and technical requirements and to the topography, as well as protect the environment from dust emissions.

IM: Are you expecting to increase your manufacturing capacity or acquire new premises to fulfil this demand, or do you have enough capacity to serve these growing markets in the near-to-medium term?

SH: The FAM Group has subsidiaries in Brazil, Chile, China, Canada and India. In addition, there are the numerous subsidiaries and agencies of the BEUMER Group. This means that we are very well positioned worldwide and can optimally serve these growing markets in the short to medium term. In our project business it’s a must to be, on the one hand, close to our customers but, on the other hand, using our global resource network and know-how to balance workloads. But, of course, we expand the network of our subsidiaries if we notice that we cannot serve certain regions with the desired reliability.

IM: Is the company already pursuing mining projects that involve the solutions/expertise of FAM and BEUMER Group? Can you elaborate on what type of projects these are and what solutions they involve (ie overland conveyors, bucketwheel excavators, spreaders, etc)?

SH: Yes, we are already in the process to support our mining clients from one hand, integrating FAM and BEUMER solutions. For example, we are working on one large project for gold extraction, where BEUMER is providing the long-distance overland conveyor and FAM supports the client with spreader technology to dump overburden. We have combined this with an attractive digitalisation and service package to ensure optimisation of the client’s total cost of ownership.

IM: With this transaction the company has effectively become a major player in the IPCC space. Do you see this as a major growth area for BEUMER Group going forward?

SH: In general, with this new setup, we expand our product portfolio and we are significantly strengthening our market position worldwide, especially in the field of large-scale mining equipment. But the most important thing is that we can provide our customers with even more comprehensive support over the whole value chain from pit to port, including digitalisation and service for our projects. Due to our many years of experience, we also support our clients in complex upgrade, lifetime extension and refurbishment jobs for existing machines. This means we avoid interfaces and customers now have only one contact.

IM: Do you see your ability to offer not only the solutions but also the engineering and design expertise underpinning these solutions as differentiating your offering from your competitors in the IPCC market? What other differentiators will serve you well in winning business in this market?

SH: I don’t want to say much about our market competitors, but I am sure that together with FAM we stand out positively from the market, specifically for continuous soft rock and overburden IPCC applications. Furthermore, we have long-term partners with whom we are serving the needs of our clients in terms of mine planning and pre-engineering. This ensures that we are defining  a solution for the client with a focus on CAPEX and OPEX optimisation. Specifically for IPCC applications, we are convinced of adding value during the first months of operation by providing integrated training and service packages to ensure successful implementation of continuous mining systems after commissioning. In doing so, the specialism is characterised in particular by distinctive engineering at a high level.

IM: What other areas of your business do you see growing with the need for mining companies to move away from their reliance on diesel-powered mobile mining equipment for material transport? Are you seeing more interest in your overland conveyor portfolio, for instance?

SH: Our belt conveyor systems are used successfully all over the world. They solve complex transport problems for any bulk material and are suitable in many cases as an economic alternative to truck transport. While the basic task – to transport bulk materials from the mine to the final discharge point – appears very comparable, no two systems are alike. The range of potential materials to be conveyed, alone, requires individual consideration of the components to be used in terms of wear resistance or the maximum permissible gradients of a conveyor. In addition, above all, the mass flow to be transported and the height to be overcome determine the dimensioning of the drive unit of an overland conveyor. Plants at high altitudes pose a further challenge. At altitudes above 4,000 m, as is often the case in the Andes for example, it must be taken into account that the air pressure and, thus, the density of the air decreases with increasing altitude. This reduces both the cooling effect and the insulating capacity of the air. We are the right project partner for all these challenges.

Sandvik completes acquisition of Schenck Process Group

Comminution of minerals, Mineral processing, Mining equipment, Mining mergers and acquisitions, , , , ,

Sandvik says it has completed the previously announced acquisition of the mining related business of Schenck Process Group (SP Mining).

SP Mining is one of the market leaders in screening, feeding, screening media and train loading solutions in the industry, according to Sandvik. It also has a strong aftermarket business, which includes application support, screen refurbishment, product engineering design and manufacturing and digital support services.

It will be reported in Stationary Crushing and Screening, a division in Sandvik Rock Processing Solutions (SRP).

The two companies already had a global partnership agreement in place dating from 2016 that brought together Sandvik’s high productivity cone crushers and Schenck Process’ high capacity multislope screens.

In 2022, SP Mining expects revenues of about €200 million ($199 million) of which approximately 70% is aftermarket, and an EBITA margin accretive to Sandvik Rock Processing Solutions’ margin, Sandvik said.

Sandvik announced the planned acquisition of SP Mining back in May.

Iron Bridge Magnetite project progresses with first ore feed milestone

Fortescue Metals Group has reached a new milestone on its majority-owned Iron Bridge Magnetite project in the Pilbara of Western Australia, with first ore fed into the processing plant.

With first production anticipated in the March 2023 quarter, Iron Bridge will see the world’s fourth largest iron ore miner deliver an enhanced product range and create 900 new jobs, it said.

Significantly, it could become one of Fortescue’s first fossil fuel free sites, enabled by the recently announced $6.2 billion decarbonisation investment to reach “real zero” Scope 1 and 2 emissions by 2030.

At a milestone event held at Iron Bridge today, Fortescue’s Executive Chairman, Andrew Forrest, was joined by Chief Operating Officer Iron Ore, Dino Otranto, Fortescue Board members, Elizabeth Gaines and Penny Bingham-Hall, representatives from joint venture partner Formosa, Western Australian Deputy Premier and Minister for State Development, Roger Cook, along with company executives, valued partners and suppliers.

Traditional Custodians also attended the milestone event to welcome over 100 guests to Nyamal country.

Iron Bridge, 145 km south of Port Hedland, will deliver 22 Mt/y of high grade 67% Fe magnetite concentrate. This product enables Fortescue to enter the high iron ore grade market segment, providing an enhanced product range while also increasing annual production and shipping capacity, it said.

Since the investment decision in April 2019, more than 12.8 million workhours have culminated in the design and construction of the mine, pipelines, village and infrastructure at Iron Bridge. There are currently 3,470 people working across the Ore Processing Facility and pipelines scope of work.

Forrest said: “At Fortescue, we take pride in the fact that we consistently deliver what we say we will, and Iron Bridge is no different. Building on our track record of safely and successfully developing and operating iron ore projects in the Pilbara, Iron Bridge will lead the way for magnetite operations in Western Australia.

“This project demonstrates Fortescue’s commitment to our strategic pillars of investing in the long-term sustainability of our iron ore business, investing in growth, maintaining balance sheet strength, as well as delivering strong returns to our shareholders.

“As we transition to a global green energy, technology and resources company, Iron Bridge is an obvious choice to be considered as one of our first decarbonised, fossil fuel free sites, as we deliver on our target to achieve real zero Scope 1 and 2 emissions by 2030.”

Otranto said: “The Iron Bridge high grade magnetite product is a significant differentiator for Fortescue, and led by the highly experienced project team, I am incredibly pleased with the significant progress made to achieve first ore feed into the processing plant.

“This is a project that has been delivered during a challenging environment, and despite a global pandemic, rising inflationary pressures and a tight labour market, the Fortescue Values have risen to the forefront and demonstrated our ability to continue delivering this ground-breaking project.”

The nature of the Iron Bridge orebodies and Fortescue’s use of a dry crushing and grinding circuit together contribute to the project’s operational efficiency across energy, water use and cost.

Low cost power will be delivered to Iron Bridge through Fortescue’s investment in the Pilbara Energy Connect project, which includes energy transmission line infrastructure, solar gas hybrid generation and associated battery storage solution.

The Iron Bridge Magnetite project is an unincorporated joint venture between FMG Magnetite Pty Ltd (69%), and Formosa Steel IB Pty Ltd (31%). The joint venture partners are each responsible for their equity share of the total capital expenditure.

Bellevue Gold on its way to achieving ‘holy grail’ with EDL pact

Bellevue Gold Limited says it has taken a pivotal step towards its aspirational goal of becoming Australia’s first ASX-listed gold miner with net-zero emissions by signing an Early Works Agreement with Energy Developments Pty Ltd and locking in long-lead items for its power station, ready for the processing plant commissioning in mid-2023.

The purchasing of the long lead items will see the company continue its carbon mitigation strategy, based off proven technologies with a Tier 1 power supplier, it said.

This agreement is a key step in Bellevue’s strategy to be powered by a forecast average of 80% renewable energy each year using a wind, solar and battery hybrid power solution.

EDL built, owns and operates a similar turnkey power solution at the Agnew gold mine, around 35 km south of the Bellevue gold project.

Bellevue and EDL are currently negotiating a Power Purchase Agreement for the project, which is subject to approval by the boards of both EDL and Bellevue.

Bellevue says its power solution is central to the company’s goal of generating the lowest carbon emissions per ounce of gold produced by any major Australian gold mine, with forecast emissions of between 0.15-0.20 t of CO2e/oz.

“As well as being the lowest emitter on a per ounce basis, the project is forecast to have the lowest total Scope 1 emissions of any major mine in Australia,” it said. “This will give the project the cleanest power supply in Australia based on a greenhouse gas per kilowatt hour basis of power generation.”

By reducing greenhouse gas emissions, with a renewable energy power station and undertaking other sustainable initiatives, Bellevue aims to produce carbon-neutral gold, giving the company a major competitive advantage in global investment markets, it says. This also provides potential for the company to seek a premium for the sale of ‘green gold’, it added.

The power station will prioritise the use of renewable energy and will also include a gas engine configuration, which, it says, will ensure there is sufficient power for the mine, even in the rare absence of solar and wind resources.

EDL will supply trucked LNG to the project to maintain optionality for any future technological innovations in thermal generation alternative fuels. Trucked LNG provides a much cleaner fuel than diesel, which was an important consideration to reduce emissions as far as possible, it said.

At a steady-state production rate of 1 Mt/y, renewable energy is expected to meet up to 80% of the project’s annual electricity needs, taking advantage of the region’s strong solar and wind resources.

Bellevue says it has been modelling the wind speeds and direction with a SODAR unit, which has allowed for the integration of wind turbines to increase the renewable energy penetration rate.

Maximising renewable energy uptake has been a key design consideration for the processing facility. The facility will have the ability to use more power – such as crushing and heating – when increased renewable energy is available, reducing thermal requirements, according to the company.

The planned infrastructure includes an oversized crushing circuit to facilitate a processing rate of more than 1.5 Mt/y (against current throughput rate of 1 Mt/y), allowing the operational flexibility in this area for an optimised match up of the renewable energy demand to the renewable energy resource.

The designed infrastructure will allow Bellevue to have a cost-effective renewable energy supply and optimise the power demand curve to better align with key daytime (solar) and night time (wind) energy peaks and troughs. Through the generation of power from renewable energy sources, it will create the optionality for the crushing circuit to maximise crushing in peak renewable energy generation periods. This will have the potential to offset more than 1 MW in demand on thermal power generation and lead to a direct cost saving and emissions reduction.

Bellevue Managing Director, Steve Parsons, said: “EDL is a leader in hybrid off-grid power stations. Their skills and experience will help ensure we maximise the use of renewable energy at the Bellevue gold project.

“Bellevue is forecasted to be a 200,000 oz a year gold miner with low all-in sustaining costs of A$1,000-A$1,100/oz ($644-$708/oz) powered by circa-80% renewable energy, with a pathway to net-zero emissions as a world-leading company in the race to decarbonise the mining sector.

“Our pre-production carbon mitigation strategy has been strategic and is world leading. It achieves the ‘holy grail’ of lower emissions and a direct cost reduction in power generation.

“The combination of these metrics is expected to will position Bellevue as one of the most sustainable and financially successful Australian gold miners, maximising returns for all stakeholders. It will also underpin the company’s strong appeal to global investors, who demand performance on both financial and ESG measures.”

On the same day as the EDL announcement, the company signed a Native Title Agreement with Tjiwarl (Aboriginal Corporation) RNTBC, being the native title rights and interests holders and traditional owners of the land which hosts the Bellevue gold project.
