JKMRC keeps tabs on Glencore Mount Isa test work via video streaming

Mineral processing experts from the Sustainable Minerals Institute’s (SMI) Julius Kruttschnitt Mineral Research Centre (JKMRC) have overcome the hurdle of COVID-19-related travel restrictions to develop a remote survey coordination method which, they say, allows them to engage with site personnel and facilitate the same procedures they would have in person through the use of video streaming.

This approach enabled the team to connect and converse directly with both the copper processing team and metallurgical laboratory at Glencore’s Mount Isa mines.

JKMRC explained: “Surveying, diagnosing and identifying improvement opportunities for processing plants generally requires teams to travel to a mine site, often in remote locations, and undertake hands-on testing alongside mine personnel − a difficult feat considering ongoing travel and distancing restrictions.”

JKMRC Senior Research Fellow and Process Performance Specialist, Lizette Verster, said the new approach offered a flexible, robust and practical alternative to the conventional method.

“Usually when one conducts a survey like this, it would involve a team of researchers travelling to a site, staying there for a minimum of a week, and working closely with site personnel,” she said.

“In this case, rather than us having a representative attend the site who coordinates the work, Glencore nominated an on-site representative who took responsibility and worked with us to ensure they had the information required to perform the survey.”

The JKMRC team set up a video link between the copper processing team and metallurgical laboratory so they could observe and direct the test work as it was being performed.

“The most important aspect of this is establishing a safe mobile link that is in line with the site’s safety requirements,” Verster said. “All remote viewing equipment allowed for hands-free operation and was protected against dust and water exposure.

“We opted to mount a smartphone on a hard hat or, alternatively a chest harness, that allowed site personnel to freely move around the plant while continuously streaming audio-visual data, and allowing for two-way communication.”

Verster said the experience the JKMRC team had at Mount Isa bodes well for using the method in the future.

“We are definitely pursuing this method going forward as it allows for the effective remote coordination of site work,” she said. “It also provides greater flexibility of survey timing which means one can make better use of operational windows for successful survey execution that doesn’t have to be pre-determined weeks in advance.

“The key to success is communication and lots of upfront planning and we are fortunate to have a close relationship with Glencore and are working with them on a number of projects.”

Glencore’s Mount Isa Mines Senior Process Engineer, Roxanne O’Donnell, was impressed with the ease in using video streaming to enable the remote testing.

“This approach minimised the need for people to come onsite and proved very effective in streamlining the analysis of our mineral processing operations,” O’Donnell said.

“At Glencore, we recognise that collaboration is the key to unlocking innovations and improvement opportunities, and we were really pleased to work with the team at the Sustainable Minerals Institute’s Julius Kruttschnitt Mineral Research Centre.”

Ausenco to work on integrating Glencore Kidd concentrator into Monarch’s Wasamac plan

Monarch Gold says it has retained Ausenco Engineering Canada to conduct an upgrading study on the Glencore-owned Kidd concentrator in connection with its potential use to treat ore mined from Monarch’s Wasamac gold project in Quebec, Canada.

The study constitutes “Phase 1” of the memorandum of understanding (MOU) recently signed with Glencore Canada, Monarch said.

Under Phase 1, Monarch is to launch a study on upgrading all or part of the Kidd concentrator and related infrastructure with a view to transporting the ore from the Wasamac property to the concentrator by railway for processing and transformation into doré bars. The upgrading study is expected to be completed by October 2020.

The study mandate calls for Ausenco to execute the study in two distinct phases. Phase one will focus on developing high-level costs and financials for two practical project options, whole ore leach and flotation leach, and phase two will develop the preferred option to a prefeasibility study level.

Located in Timmins, Ontario, the Kidd concentrator was built in 1966 with numerous upgrades over the years. It currently processes metal ore to produce copper and zinc concentrates, with the facility having a design rated capacity of 12,500 t/d. The site has incoming and outgoing rail service via Ontario Northland Railway.

Jean-Marc Lacoste, President and Chief Executive Officer of Monarch, said: “We are excited to be working with an engineering firm like Ausenco, which has produced numerous solid studies and developed successful large mining projects around the globe, including recent and relevant benchmark projects such as Moose River gold (Nova Scotia).

“Ausenco has a strong track record of delivering project studies that go the extra step in optimising the project economics.”

Garry Warren, President North America Project Delivery of Ausenco, said: “Ausenco has a project development ethos centred on cost-effective process and rail design coupled with efficient delivery, driving strong project economics and return on shareholder investment.

“We intend to apply that ethos to provide a differentiated approach for the Wasamac project, one that extracts the maximum value for Monarch and sets the stage to move from the upgrading study into project execution and commercial production.”

The December 2018 feasibility study on Wasamac forecast average annual production of 142,000 oz of gold for 11 years at a cash cost of $550/oz.

Swedish Stirling powers up South Africa ferrochrome industry advances

Swedish Stirling AB’s container-based energy recycling solution is taking off in South Africa’s ferrochrome sector, with two of the largest producers on board with the technology.

Based close to Gothenburg, Swedish Stirling Group is a clean tech company with a mission to scale up the conversion of thermal energy to electricity.

It is the company’s latest product – the PWR BLOK 400-F – that is finding favour in South Africa. This is a unique proprietary solution that uses Swedish Stirling’s Stirling engines for recovering energy from industrial residual and flare gases and converting them to 100% carbon-neutral electricity at a high rate of efficiency, according to the company.

The PWR BLOK 400-F contains 14 Stirling engines and delivers a net output of 400 kW.

Citing an independent certification, Swedish Stirling says the PWR BLOK is the cheapest way to generate electricity that exists today, yielding greater CO2 savings per Euro invested than any other type of energy.

Ferrochrome is renowned for being an energy-intensive process and load shedding is a common practice in power-constrained South Africa, hence the reason why it has been one of the frontrunners in adopting this technology.

Swedish Stirling explained: “Many industrial applications produce by-products in the form of gases (residual gas) that are currently burned without harnessing its energy content. Several solutions have been tried to recycle the energy in the gases.

“In the ferrochrome industry in South Africa, producers have tried to recover the energy using internal combustion engines, gas and steam turbines, but all solutions have failed. The reason is usually that the gas is of such uneven quality that most engines with internal combustion don’t work, or the technical solutions are extremely costly.

“The Stirling engine, on the other hand, is, due to its external combustion, almost insensitive to the type of gas that is burned or the quality of the gas in question. Therefore, it is now possible to start converting these residual gases into climate-smart electricity with PWR BLOK.”

And, this is exactly what is happening.

After installing a test PWR BLOK at Afarak Mogale’s smelter in South Africa over a year ago, the company has sealed contracts with Glencore and Samancor.

In the recent March quarter results, Swedish Stirling CEO, Gunnar Larsson, said: “Together, these (companies’ output) account for over 90% of the entire market in the country. This gives us a solid base for a wider-scale roll-out of the PWR BLOK in South Africa in the coming years.”

The agreement with Glencore will see it install and deliver up to 25 PWR BLOKs, generating 9.9 MW, to the Lydenburg smelter, while Samancor has signed up for a pilot facility with one PWR BLOK unit at the TC Smelter facility.

The company also, earlier this year, arranged a tour of the Mogale smelter for interested parties to spur further enquiries.

While the spread of COVID-19 has somewhat affected the company hitting its deadlines for these projects, it made progress with the Samancor delivery early last month, confirming that, after spending a number of weeks on a ship in Durban Harbour during the COVID-19 lockdown in South Africa, a PWR BLOK 2 unit was unloaded for transport to Samancor’s TC Smelter (pictured).

The company still hopes to install and commission the facility at TC Smelter during the June quarter as planned.

The agreement with Glencore’s Lydenburg smelter, meanwhile, could see carbon dioxide emissions from the smelter reduce by more than 80,000 t/y, due to the reduced need for purchased electricity, Swedish Stirling previously said.

ADE and Austin Engineering-designed water trucks delivered to Glencore mine

Australian Diversified Engineering (ADE) and Austin Engineering have come together to improve dust control and enhance safety at the Glencore-owned McArthur River mine in the Northern Territory of Australia.

ADE’s revolutionary water spray application technology and Austin’s innovative Stairway Access Tank (SAT) are now embedded in two uniquely designed CAT 789 water trucks, which have a 159,000 litre capacity, on site at the operation.

The zinc-lead-silver mine had contracted EPSA to supply and maintain mobile equipment on site and required two new water trucks to be added to its operations, ADE said. Being mindful of improving dust control and ensuring better safety for its workers, it decided to have the trucks specifically designed for the application at hand.

The exclusive design has produced what is now known as the safest water tank in the mining industry, according to ADE. It is an engineering collaboration of which ADE General Manager, Clive Gray, says has set a new bar for water truck technology.

“Controlling airborne dust on mine sites is incredibly important,” he explained. “It minimises the risks to workers, but knowing just how much water to spray has its own challenges and can also become a hazard, leading to unplanned vehicle movement and, even worse, closing a haul road for many hours.

“We have been manufacturing safety equipment for the mining industry for many years but being able to work together with Austin Engineering has allowed us to deliver an exceptional solution for the McArthur River mine. We feel confident that they will see positive outcomes in terms of improved safety and better dust control very quickly, making this a great investment.”

The water truck-based ADE Spray System is a spray control system that consistently sprays a controlled rate of water onto the ground, regardless of speed, to effectively control airborne dust, according to ADE.

Road friction measurements can be used to determine the maximum safe water coverage rate which, in turn, reduces waste and decreases the risk of an unplanned movement. During operations, the system data logs all spray activities which can be used to generate reports and assess operations.

Gray says it is the ability to both measure and monitor that makes the ADE Spray System such a game changer.

“One of the biggest issues for mine sites is knowing how much water to spray on the road,” he said. “Too much or too little have equal repercussions, with safety issues being the greatest concern.

“Mining operators can quickly and easily monitor and track all aspects of their water truck operations using our on-board data logging system, which effectively cuts costs and improves environmental factors in regards to monitoring water usage.

“By eliminating over and under watering, costs, fuel and water usage are naturally reduced, but it is the safety of the mining workers that is at the forefront of our designs.

“By developing and implementing innovative technologies into mines around Australia we limit the risks involved to mining workers, and that is something we are very proud of.”

Austin’s truck-mounted SAT system, meanwhile, includes several features to improve efficiency, operator safety and truck stability, Austin says. The most obvious external feature of the Austin water tank is a stairway from the top of the tank structure down to a large (137 cm x 259 cm) access port for easy entry and exit for personnel and maintenance equipment to the tank interior. The fill port is located behind the water dam to ensure any overflow flows away from the cab and deck to the rear of the truck, Austin says. This helps significantly improve operator safety and comfort inside the tank.

The custom designed CAT 789-based trucks began their journey in Wyoming, USA, where they were initially designed, before then being manufactured in Batam, Indonesia. The trucks were then assembled in Australia by Austin Engineering before ADE engineers installed its latest safety technology, ADE said.

The trucks were then delivered to the mine site where ADE engineers arrived to ensure all components were running as planned before the trucks started their first day of action.

Murrin Murrin nickel mine to benefit from new Bis road trains

As part of a major upgrade to its off-road haulage fleet at Minara Resources’ Murrin Murrin nickel mine in Western Australia’s north-eastern Goldfields, Bis’ operational teams have welcomed new 350 t Dual Powered Road Trains (DPRTs) to site.

Bis’ high-payload proprietary road trains deliver customers reduced haul cycles and vehicle movements – leading to higher productivity at reduced costs, the company says.

Bis has been providing a range of services at Murrin Murrin (wholly owned by Glencore), including haulage and haul and road maintenance services, calcrete services, and bulk logistics services, since the operation began in 1998. Last year, it extended its haulage and site services contract for a further four years.

AGQ Labs to keep environmental tabs on Glencore’s Contonga polymetallic mine

AGQ Labs’ mining division has been awarded a contract to carry out the environmental monitoring of the quality of soil, water, plant and hydrobiological tissue at Glencore’s Contonga polymetallic mine, in Peru.

The Contonga mine, in Ancash, is owned by Glencore subsidiary Compañía Minera Los Quenuales. It is a polymetallic underground zinc, lead, copper and silver mine with more than 100 years of operating history, according to AGQ Labs. Glencore acquired the asset from Nyrstar back in September 2017.

The mining company, as part of its environmental commitment at the mine, performs environmental monitoring of its components to determine their chemical stability and the potential for acid mine generation, as well as their characterisation through complementary studies, AGQ Labs said.

AGQ Labs Mining will provide the sampling service and technical analytical support through a specialised service for the characterisation of soils, waters and plant tissue. This uses selective analytical techniques for the characterisation of the matrices under study.

For this, AGQ Labs uses a set of tests to define the quality of the soils under study through fertility tests and characterisation of the profiles.

Mobilisation of the different analytes under study are also characterised through leaching tests such as methodologies proposed by Tessier and the Flask Extraction Test. The characterisation of its acid generation capacity with ABA methodologies and mineralogy analysis is carried out with Thin Sheet Microscopy.

AGQ Labs said: “The characterisation works are complemented by the taxonomic classification of the most representative flora and the study of the waters through laboratory analyses of physicochemical and hydrobiological parameters.”

CSIRO maps out laser scanning solution for underground coal mines

New real-time underground 3D mapping technology developed by CSIRO can be used to locate, steer and navigate equipment and vehicles in volatile, methane-rich underground environments, according to Australia’s national science agency.

ExScan technology, being trialled by Glencore, as well as five other mining companies, has a laser scanner and associated software capable of generating real time 3D maps of tunnels, walls and cavities underground where global positioning system (GPS) cannot penetrate. These maps can be used for locating, steering and navigating equipment and vehicles.

Arguably, the real innovation in CSIRO’s new underground mapping technology is not the smart laser-based scanner, but the container in which it sits, CSIRO said.

“The enclosure has been certified to International Electrotechnical Commission ‘Ex d’ standards for use in volatile, methane-rich underground environments such as coal mines,” the agency said.

“That means it has been designed to prevent the electronic equipment it houses sparking an explosion.”

CSIRO Electronic Engineer and ExScan Project Lead, Peter Reid, said: “Nothing can go underground in a coal mine unless it’s certified to be in that environment. You can’t even take an aluminium can; it’s a potential spark hazard if it gets crushed by a vehicle. So getting electronics down there is a tricky process.”

The problem is that explosive gases such as methane penetrate equipment and any failure of electronics that causes a spark could lead to a fiery disaster.

The solution outlined in the Ex d regulation is not to contain explosions, but to prevent them from happening in the first place. That’s achieved by designing the container to ensure any spark would have to travel such a long way to encounter sufficient gas to trigger an explosion and, by that time, it will have cooled below the ignition point, CSIRO said.

Looking to longwalls

Many members of CSIRO’s ExScan development team spent years working with industry on the Australian Coal Association Research Program-funded project that developed the successful LASC longwall automation system.

A major driver behind automating coal mining is to remove people from the dusty, hazardous environment near the coal face, but even the LASC automated equipment occasionally needed hands on human measurement to guide it through trickier parts of the coal seams.

The idea behind ExScan was to provide images that could be used to make those measurements automatically, CSIRO said.

“This technology provides us with information that cameras on their own can’t,” Reid said. “It allows us to measure in 3D anything we see, as if we were there.”

The LASC ExScan is a 3D scanner, housed in an explosion-proof casing, that can map tunnels, voids and cavities in real-time underground.

What emerged looks a little like a 25 cm-high version of Star Wars character R2-D2 – with a steel base into which a polycarbonate dome screws, CSIRO said. The laser sits under the transparent dome and scans through it. To get outside into a volume of gas, any spark generated would have to work its way through a narrow sawtooth path formed by the screw thread and, in doing so, would lose most of its energy.

Should the scanner malfunction or the container become scratched or damaged, it can be swapped over in a matter of minutes, because the dome just screws off, CSIRO explained.

The team invested a lot of time in computer modelling to come up with a dome that was just right for injection moulding. That makes the ExScan devices relatively inexpensive to manufacture, according to CSIRO.

“In fact, they are affordable enough for a line of 40 or 50 to sit behind the mining equipment along a longwall face of between 400 and 500 m in length, providing real time updates of the condition of the wall,” it said. “At 10 metres apart, the devices are close enough to allow redundancy – their scans overlap, which means that if one fails, its absence can be covered by others on either side to ensure overall reliability.”

Removing people from the coal face

According to Glencore Technology Superintendent at Oaky North mine, in central Queensland, Lauris Hemmings, the images they generate can be used to determine and sort out coal flow blockages on the conveyor system under the shearing equipment and to help align and steer the shearers themselves.

“It’s a fantastic tool,” Hemmings said, “an ever-evolving piece of equipment that takes risk management to even higher levels.”

The mine is already hoping ExScan can be used to navigate the higher risk areas of the mine, taking employees away from the coal face.

But the applications are broader. The scanners can be mounted in any orientation – even upside down – and on moving machinery and vehicles. This means they can be used to map whole mines, and potentially for vehicle navigation, CSIRO said.

The containers themselves can be employed for other electronic purposes, such as housing camera systems, and are already being marketed separately by Eaton Industries.

In addition to Glencore, the LASC ExScan system is being trialled by five other Australian mining companies, as well as by companies overseas.

“The Chinese coal industry has become so interested that it has invested the resources for a couple of engineers to develop skills to deal with the large amount of data generated by the scanners,” CSIRO said. “The feedback from all this activity is allowing the CSIRO team to develop new features for the scanner.”

CSIRO is now determining next steps to commercialise the ExScan system.

ICMM looks to align mining industry on cleaner, safer vehicles

When the International Council on Mining and Metals (ICMM) launched its Innovation for Cleaner, Safer Vehicles (ICSV) program just over a year ago, some industry participants may not have realised how much progress could be made so quickly by taking a collaborative approach.

The ICMM has proven influential across the mining industry since its foundation in 2002 in areas such as corporate and social governance, environmental responsibility, and stakeholder relations, yet it has rarely, until this point, engaged directly as an industry group with original equipment manufacturers (OEMs) and service providers.

Close to 12 months after being established, it’s clear to see the program and the council itself has been successful in bridging a divide.

It has been able to corral a significant portion of the mining and mining OEM market players into a major industry discussion on core focus areas set to dominate the sector for the next two decades.

Now 27 of the world’s leading mining companies and 16 of the best-known truck and mining equipment suppliers are collaborating in a non-competitive space “to accelerate the development of a new generation of mining vehicles that will make vehicles cleaner and safer,” the ICMM says.

The ICSV program was created to address three of the most critical safety, health and environment performance issues in the ICMM’s mission towards zero harm and decarbonisation. Achieving this goal would involve the industry introducing and adopting the next generation of equipment to respond to the challenges.

More specifically, the program aims to:

  • Introduce greenhouse gas emission-free surface mining vehicles by 2040;
  • Minimise the operational impact of diesel exhaust by 2025; and
  • Make collision avoidance technology (capable of eliminating vehicle related collisions) available to mining companies by 2025.

In all three, it seeks to address the industry’s innovation challenge of ‘who motivates who’ or the chicken and egg analogy, according to Sarah Bell, Director, Health, Safety and Product Stewardship for the ICMM.

“You can imagine a mining company saying, ‘we can’t adopt technology that doesn’t yet exist’ or an OEM saying, ‘we can’t invest in development because we’re getting mixed market signals’. This is, of course, why this program has been set up in the way it has,” she told IM. “Bringing both the mining company and OEMs together, they have been able to work through these normal innovation challenges and align on defining the direction of travel and critical complexity to be solved for each of the ambitions set.”

High-level participation

The list of companies the ICMM has been able to involve in this program is impressive.

It is being guided by a CEO advisory group of six; three from the mining community – Andrew Mackenzie (CEO, BHP), Mark Cutifani (CEO, Anglo American) and Nick Holland (CEO, Gold Fields) – and three from the mining equipment supply side – Denise Johnson (Group President of Resource Industries at Caterpillar), Max Moriyama (President of the Mining Business Division at Komatsu) and Henrik Ager (President of Sandvik Mining and Rock Technology).

On the mining company front, ICMM membership makes up around 30% of the total metal market share, with some 46% in copper, 27% in gold and 42% in iron ore. Participating OEMs and third-party technology providers, meanwhile, include the three majors above, plus Cummins, Epiroc, Wabtec Corporation (formerly GE), Hexagon Mining, Hitachi Construction Machinery, Liebherr, MacLean Engineering, MTU, Modular Mining Systems, PBE Group, Nerospec, Future Digital Communication and Miller Technology.

Bell says the high-level participation builds the “widespread confidence” needed to accelerate investment in these three key areas”, while the ICMM’s focus on the leadership side of the technology integration equation and change management has proven “absolutely key”.

She clarified: “This collaboration operates under anti-competition and anti-trust rules. Our role is to convene the parties, motivate action and promote solutions.”

The program offers a “safe space for the OEMs and members to work openly in a non-competitive environment”, she added, explaining that the aim is not to come up with “preferred technologies”, but define the “functional and operational pathways required to meet the ambitions set”.

Vehicle interaction (VI)

Some of the ambitions look easier to achieve than others.

For instance, collision avoidance and proximity detection technology has made huge strides in the last decade, with the ICMM arguing its 2025 target is like a “sprint”, compared with the “10,000 m race” that is minimising DPM underground by 2025 and the longer-term aim to introduce GHG-free surface mining vehicles by 2040.

“There are regulations that require implementation of collision avoidance and proximity detection technology by the end of 2020 in South Africa,” Bell said. This will undoubtedly provide a catalyst for further developments to speed up.

The ICSV program is also leveraging the work of the Earth Moving Equipment Safety Round Table (EMESRT) in its development of fundamental functional/performance requirements for operators and technology providers.

These requirements were updated and released by EMESRT in September and are known as ‘PR5A’.

Credit: Hexagon Mining

Bell delved into some detail about these requirements:

“The EMERST requirements are designed around a nine-level system that seeks to eliminate material unwanted scenarios such as – equipment to person, equipment to equipment, equipment to environment and loss of control,” she said.

“The fundamental change with this newly released set of functional requirements by EMESRT is that the mining industry users have defined the functional needs for levels 7-9 (operator awareness, advisory controls, and intervention controls). That stronger level of collaboration hasn’t necessarily been there.”

EMESRT and its guidelines have been given an expanded global platform through the ICMM’s ICSV, with the program, this year, providing the convening environment for users and technology providers to help finalise these updated requirements, according to Bell.

With all of this already in place, one could be forgiven for thinking the majority of the hard work involved with achieving the 2025 goal is done, but the working group focused on VI knows that while OEMs continue to retrofit third-party vehicle collision and avoidance systems to their machines the job is not complete.

“Let’s think about the seatbelt analogy: you don’t give buyers of vehicles a choice as to whether they want a seatbelt in their car; it just comes with the car,” Bell said.

“At the moment, by design, vehicles don’t always have this collision and avoidance systems built in, therefore there is a big opportunity for collaboration between OEMs and third-party technology providers.”

Underground DPM goals

“The DPM working group have recognised that, in the case of the DPM ambition, ‘the future is already here, it’s just unevenly distributed’,” Bell said.

“Bringing together the OEMs and the mining companies this year through the ICSV program has enabled the group to explore the variety of existing solutions out there today,” she added.

These existing solutions include higher-tier engines, battery-electric equipment, tethered electric machinery, fuel cell-equipped machines for narrow vein mining and solutions to remove DPMs and other emissions from the environment like Johnson Matthey’s CRT system.

And, there are numerous examples from North America – Newmont Goldcorp at Borden, and Glencore and Vale in Sudbury – South America – Codelco at El Teniente Underground – and Europe – Agnico Eagle Mines at Kittilä (Finland, pictured) – to draw from.

Bell also mentioned some examples from Australia where regulatory changes have seen miners apply existing technology and carry out changes in their work plans and maintenance practices to minimise DPM emissions.

Haulage and loading flexibility, battery charging and mine design have all come under the spotlight since these new generation of ‘green’ machines have emerged, so achieving the 2025 goal the ICSV stated is by no means a foregone conclusion.

“There remains more work to do in achieving diesel-free vehicles underground,” Bell said.

The interested parties are aware of this and the program’s DPM maturity framework is helping miners and OEMs plot a course to reaching the target, she explained.

“The DPM maturity framework promotes existing solutions available today that would enable a mining operation to reduce their DPM emissions to a level that would meet the ambition level (shown as Level 4 – transition to zero),” she said.

These frameworks are useful for starting a “change conversation”, Bell said, explaining that mining companies can assess within their organisations where they currently sit on the five-level chart and discuss internally how to move up the levels to meet their goals.

These same frameworks look beyond minimising “the operational impact” of DPM emissions underground, with Bell explaining that Level 5 of the maturity framework involves “non-DPM emitting vehicles”.

GHG-free surface mining vehicles

Even further in the distance is the longer-term target of introducing greenhouse gas emission-free surface mining vehicles by 2040.

This ambition, more than any other, is less clearly defined in terms of technological solutions across the industry.

While battery-electric solutions look like having the goods to reach DPM-free status underground with expected developments in battery technology and charging, the jury is still out on if they can create a GHG-free large-scale open-pit mining environment.

The world’s largest battery-electric haul truck – eMining’s 63-t payload eDumper (pictured) – may have proven its worth at a Ciments Vigier-owned quarry in Switzerland, but the world’s largest open-pit mines require a solution on another scale altogether.

As Bell said: “There is a lot of work to do to develop batteries at scale for surface fleet that suit the different operating conditions.

“That’s a key point because that lends itself to the fact that we don’t want one solution; we will need multiple solutions. We don’t want to stifle innovation; we want to encourage it.”

ICMM member Anglo American has hinted that hydrogen power could be one solution, and the miner is looking to show this next year with the development of its hydrogen-powered 300-t payload haul truck.

There has also been in the last 18-24 months a mini renaissance of trolley assist projects that, ABB’s Gunnar Hammarström told IM recently, could, in the future, work in tandem with battery-powered solutions to provide a GHG-free solution.

The ability for industry to pilot and validate technology options like this “within the boundaries of anti-competition” is crucial for its later adoption in the industry, Bell said.

She said a key enabler of industry decarbonisation is access to cost competitive clean electricity, which would indicate that regions like South America and the Nordic countries could be of interest in the short and medium term for deploying pilot projects.

It is this goal where the industry R&D spend could potentially ramp up; something the ICMM and the ICSV is aware of.

“For the OEMs and mining companies to effectively minimise capital expenditure, optimise R&D expenditure and reduce the change management required by the industry, there needs to be a careful balance of encouraging innovation of solutions, whilst managing the number of plausible outcomes,” Bell said.

In terms of encouraging the development of these outcomes, carbon pricing mechanisms could provide some positive industry momentum. Vale recently acknowledged that it would apply an internal carbon tax/price of $50/t when analysing its future projects, so one would expect other companies to be factoring in such charges to their future mine developments.

Industry-wide GHG emission caps could also provide a catalyst. In countries such as Chile – where up to 80% of emissions can come from haul trucks, according to ICMM Senior Programme Officer, Verónica Martinez – carbon emission reduction legislation could really have an impact on technology developments.

Forward motion

While 2019 was a year when the three working groups – made up of close to 50 representatives in each work stream – outlined known barriers or opportunities that might either slow down or accelerate technology developments, 2020 will be the year that regional workshops convened to “encourage first adopters and fast followers” to move these three ambitions forward take place, Bell said.

A knowledge hub containing the previously spoken of maturity frameworks (delivered for all three groups) will allow the wider industry outside of the ICMM membership to gain a better understanding of how the miner-OEM-service provider collaboration is working.

Bell said the ICMM already has a number of members testing these group frameworks on an informal self-assessment basis to understand “how they are being received at an asset level and feedback insights to the group in an effort to understand how we may portray an industry representative picture of where we are today”.

Such strategies bode well for achieving these goals into the future and, potentially, changing the dynamic that has existed between end users and suppliers in the mining sector for decades.

Bell said: “The feedback that we got from OEMs is that mining companies had completely different objectives, but they have now greater confidence that we are aligned on the direction of travel towards the ambitions set.”

MAXAM ready to blast at Glencore’s Lomas Bayas copper mine

MAXAM is to supply its high-energy bulk explosive, RIOFLEX, alongside other solutions, to the Glencore-operated Lomas Bayas mine, in Chile, as part of a blasting services contract.

The Lomas Bayas open-pit copper mine is in northern Chile and produces copper cathode on site. In the first half of 2019, Lomas Bayas produced 40,000 t of copper metal, up from 33,800 t a year earlier, Glencore said.

MAXAM said: “With this contract, MAXAM continues to expand its operations and global presence, and currently has more than 80 industrial facilities, subsidiaries in more than 50 countries on five continents and 6,500 employees worldwide.

“In fact, MAXAM is the second largest operator of blasting solutions for mining, quarries and infrastructure in terms of international presence.”

RIOFLEX is a highly energetic, robust and flexible density bulk product that, MAXAM says, achieves excellent performance in all types of rock. It has been tested in more than 140 sites in 25 countries.

Diego Rodríguez, Regional Director of MAXAM in Latin America, said: “We are delighted to collaborate with Minera Lomas Bayas and offer our innovative solutions in the operation. At every operation, our clients always highlight our closeness and experience, contributing to improve their efficiency and productivity, something that we will undoubtedly also deliver in Lomas Bayas.”

Sandvik showcases digital mining developments in Brisbane

Last week, close to 300 leaders from the mining, construction and quarrying industries from Australia, Japan and Indonesia met in Brisbane, Australia, for a two-day summit, hosted by Sandvik, to showcase best practice examples of digitalisation.

The Digitalization in Mining event, on December 3-4, allowed Sandvik to demonstrate its latest digital offering and introduce participants to the latest innovations across its product portfolio, including process optimisation with OptiMine®, information management through My Sandvik digital services and autonomous operation with AutoMine ̶ together with the latest equipment in underground and surface drilling, loading and hauling, crushing and screening and the rock tools management system.

During the event Sandvik also announced two product launches: AutoMine Access API, which gives mines the power to connect non-Sandvik equipment to AutoMine, and its first Stage V compliant underground loaders for hard-rock mining applications.

Jim Tolley, Vice President, Sales Area Australia Pacific, Sandvik Mining and Rock Technology, said digitalisation is helping companies to grow and optimise their operations. “Our partners were keen to join us at this event because they know that digitalisation has a critical part to play in making their mines sustainable for the future.”

Day one of the event featured speakers from mining companies across Australia, as well as leaders in mining technology, process optimisation and automation. They explained the benefits their organisations have gained by implementing automation and process optimisation solutions, as well as the accompanying change in mindset, according to Sandvik.

The following presentations set the program for the day, followed by a panel discussion:

  • Shaping the Industry Digital Ecosystem (Sandvik);
  • Holistic Perspective, Focusing on Productivity, Safety and Optimised Machine Performance (Byrnecut);
  • Developing the Mine of Tomorrow (Barminco Ltd);
  • Machine Learning  ̶  Keeping it Real with Case Studies from across the Mine Value Chain (PETRA Data Science);
  • Capturing Opportunities for Digital and other Product Technology Solutions (Rio Tinto);
  • Automation Technology to Improve Efficiency and Consistency in Longwall Development Operations (Glencore);
  • Direction of Technology and Automation (Newcrest); and
  • Data Privacy, Rights and Control (Sandvik).

Pat Boniwell, Managing Director, Byrnecut Australia, said the industry will improve productivity, safety and optimise machine performance through a more “fundamental understanding” of the individual processes that make up our operations.

“New technology, automation, data transfer and analysis will all assist us in increasing the utilisation of our resources,” he said. “Data is essential, but if it is not being looked at then we are just gathering data for the sake of it. We need to continue to increase the levels of engagement between all stakeholders.”

He concluded: “We are doomed to failure unless we take our people with us and are prepared to question and be challenged.”

PETRA CEO, Penny Stewart, meanwhile, homed in on machine learning, which, she said, powers “digital twin prediction, simulation and optimisation to increase mine productivity, efficiency and yield, by showing engineers and supervisors how to reproduce their ‘best performance’ 24 hours a day, seven days a week”.

She added: “PETRA’s MAXTA™ Suite digital twin applications provide platform agnostic software-as-service operational decision support across the mine value chain ̶ from resource engineering through to processing plant set point optimisation.”

Day two of the event began with a presentation on sustainability by Henrik Ager (pictured), President, Sandvik Mining and Rock Technology, explaining how critical it is for long-term performance.

“Driving productivity and greenhouse gas efficiency together is going to be key for us at Sandvik, improving productivity and greenhouse gas efficiency will be the best way for us to add value for our customers,” he said. “My view is that the more we link our sustainability targets to normal business targets and find ways to combine them to achieve a common good, the better chance we have to deliver on them.”

Also, during the second day, delegates had the opportunity of a virtual visit to several Sandvik customers, including: Northparkes Mine (Australia), Resolute Mining Syama mine (West Africa), RedBull Powder Company (New Zealand) and Aeris Resources Tritton mine (Australia).

Harry Hardy, General Manager Customer Accounts, Applications Engineering and Marketing, Sandvik Mining and Rock Technology, Sales Area APAC, said the company often gets asked for reference cases and data to illustrate the value and payback of digital solutions. “Over the two days of the conference, our customers were able to share their own experiences and quantitatively demonstrate how our solutions have helped increase their productivity, reduce their production costs and increase their safety.”
