Komatsu’s pre-production Power Agnostic 930E haul truck heading to Boliden’s Aitik mine

Komatsu has announced a significant step forward in their joint commitment to sustainable mining together with Boliden, a leading global mining and metals company with a strong focus on sustainable production.

At MINExpo 2024, Komatsu unveiled its all-new Power Agnostic 930E haul truck, built on Komatsu’s modular power-agnostic platform, this new generation truck allows customers to future-proof their operations with a versatile approach to decarbonisation.

Thanks to this modular power-agnostic platform, customers are able to start with conventional diesel engines and gradually transition to cleaner energy sources as needed. Whether adopting battery technology, hydrogen fuel cell technology or a combination of energy systems, the Power Agnostic 930E provides the infrastructure and adaptability necessary to meet evolving sustainability goals.

Following the exhibition, this pre-production haulage truck will make its way to Boliden’s Aitik mine – Europe’s largest and one of the world’s most productive open-pit copper mines. This marks a milestone moment as the truck will become the first of its kind to undergo field testing in production at a customer’s mine site including the ambition of conversion to battery technology.

This one-year field trial will take place within the Komatsu Greenhouse Gas (GHG) Alliance framework, where Boliden will work closely with Komatsu to gather first-hand insights and feedback based on real-world applications. This collaboration will contribute to the advancement of Komatsu’s power-agnostic truck concept.

“We are excited to continue our partnership with Boliden in their Aitik mine, where the Power Agnostic 930E truck, showcased at MINExpo, will soon start the first field trials in a customer mine site,” Jeroen De Roeck, Senior Manager Mining for Komatsu Europe. “This milestone not only represents a major step forward in our decarbonisation strategy but also exemplifies our commitment to support our customers in achieving their sustainability goals. Together with Boliden, we are paving the way for a more responsible mining industry.

As one of the founding members of the GHG Alliance, Boliden has consistently demonstrated its commitment to ambitious carbon reduction goals within the mining industry.

In 2023, Boliden became the first company in Europe to implement Komatsu Frontrunner, an Autonomous Hauling System, on 17 haul trucks at the Aitik mine. This initiative aimed to optimise productivity and asset utilisation to meet increased transportation demands while maintaining world-leading cost competitiveness.

As the demand for essential minerals continues to grow, mining companies face increasing pressure to deliver these crucial resources productively and responsibly. Komatsu is focused on supporting mining operations in meeting these challenges through innovative solutions that prioritise both productivity and climate performance.

Boliden Kevitsa, Sandvik to jointly test battery-electric concept surface drill rig

Sandvik Mining and Rock Solutions and Boliden’s Kevitsa mine have signed a collaboration agreement to test and develop Sandvik’s battery-electric concept surface drill rig in order to gain real-world data on its operation and performance.

Boliden Kevitsa, a multi-metal open-pit mine in Sodankylä, Northern Finland, is known for efforts to minimise environmental impact while maximising the energy efficiency of the operation. The mine invests constantly in automation, electrification and remote-control systems, all standout features of the Sandvik battery-electric concept surface drill rig.

The modern infrastructure at Kevitsa makes it an ideal field-testing lab for the new concept drill rig, which Sandvik introduced in November 2023. The lessons learned jointly during the testing period will be used to further develop the concept machine. The harsh Arctic conditions and Kevitsa’s strict mining standards will ensure a demanding trial environment for the concept rig’s productivity, safety and sustainability features.

“Sandvik’s battery-electric concept surface drill rig is a testament to our mission to gear our value chain towards net zero emissions,” Lauri Laihanen, Vice President, R&D, Surface Drilling, Sandvik Mining and Rock Solutions, said. “Most of the emissions generated in the Sandvik value chain come from the use of our products, so minimising these emissions is a priority that will contribute both to the sustainability of the end-products and global sustainability efforts overall.”

The battery-electric concept surface drill rig combines the flexibility of battery operation with the endurance of a power cable. The battery pack, which lasts for up to one hour of drilling or up to seven hours of tramming, is primarily intended for tramming and drilling individual holes, while the bulk of production relies on more than 180 m of tethered cable.

In addition to increased freedom of movement and flexibility, the benefits of battery operation also include higher utilization rates because the rig can immediately start drilling at a new location while the cable is still being set up. The more manageable tether, thanks to its simple setup with automatic tightening and smaller cable diameter, serves to make the cable operation as effortless as possible.

Boliden’s sustainable metals supply strategy on show at Rävliden

Boliden is used to setting the standard in mining, and its latest innovation leap focused on electrification at the Rävliden mine in northern Sweden is another example of it leading from the front.

The Sweden-based company has a vision of being the most climate-friendly and respected metal provider in the world, and, from what IM witnessed and heard last month during a visit to the extension of the Kristineberg mine, Rävliden, it is well on its way to doing that.

The group climate targets that were validated and approved by the Science Based Targets initiative at the back end of 2023 – reducing absolute CO2e Scope 1 & 2 emissions by 42% in 2030 from the 2021 baseline among these – are important markers for Boliden, but what is even more impressive is the actions being taken on the ground to hit these.

Among them are the addition of numerous battery-electric vehicles into the underground operating fleets in the mines within the Boliden Area and Garpenberg, the open-pit trolley assist achievements made with diesel-electric drive trucks at Aitik and Kevitsa and, at the Smelting divisions, major investments in recycling. This is underpinned by energy inputs that are from predominantly fossil fuel-free grids or with captive green energy supply.

This has allowed the company to establish Green Transition Metals (GTM): a portfolio of recycled and low-carbon metals that it sells on the market and act as a key differentiator in the commodity space. To this point, these products have allowed the company to access forms of finance unavailable to competitors lacking such green credentials.

The philosophy behind this tangible example of sustainable commodity supply has been felt upstream and downstream of Boliden HQ, as confirmed by Patrik Westerlund, Boliden Senior Development Engineer.

Westerlund is responsible for the underground truck trolley project at Rävliden and says he has felt the backing and involvement of management at every turn of the project.

“Whenever reporting on progress on the project, I have felt support from management,” he told IM. “Innovation is encouraged from the top down at Boliden.”

Battery truck trolley first

In 2021, the company outlined a SEK1.25 billion ($123 million) investment at Kristineberg towards further developing the mine towards the Rävliden mineralisation. This expansion was expected to contribute to an increase in milled volumes in the Boliden Area to 1.8 Mt/y.

A satellite deposit close to Kristineberg – which, itself, has been operating since the 1940s – Rävliden constitutes a sub-vertical to steeply south-dipping, 5-25-m wide and 150-m high mineralised lens, or system of lenses, with a length extent of at least 900 m along plunge. The mineralisation at Rävliden is broadly of a similar character to Kristineberg although is amenable to both long-hole stoping and transversal open stoping – as opposed to the cut and fill mining and drift and fill mining methods utilised to mine the mineralised material underground at Kristineberg.

Exploration of the Rävliden mineralisation has resulted, to date, in 8.4 Mt of inferred and indicated mineral resources. The deposit contains copper, zinc, lead, silver and gold, with mining rates of 800,000 t/y making for a 10-year operation.

Where the project gets very intriguing – and the reason for IM’s visit – is in the company’s haulage plan.

Where Kristineberg uses a 160 t/h skip hoist to get the crushed ore to surface, Rävliden is expecting to transport its ore, waste, concrete and personnel using a 5.6-km ramp stretching from surface to 750 meters underground, at an average incline of 1:7.

This will represent a world-first battery-trolley operation, which the company is already proving out via an 800-m trolley test track – also a world first.

Back in April, Boliden, Epiroc and ABB passed a new technology milestone by successfully deploying the first fully battery-electric truck trolley system on this test track, which boasts a 14% incline as well as a curve with a 35-m-long radius.

IM, during late August, witnessed one of these fully loaded Epiroc battery-electric Minetruck MT42 SG Trolley trucks in operation at the mine, along with the supporting infrastructure supplied by ABB and others. The on-board truck infrastructure includes ABB’s DC-DC converter, HES880 inverters and AMXE motors to enhance the power of the machine, while there are off-board rectifier substations for the track. The ABB Ability™ System 800xA® was also showcased during the visit, which monitors and controls the electrical system. In addition, Siemens provided on-board hardware for the MT42 SG Trolley truck.

The truck features a trolley pantograph connected to an overhead catenary line, which is similar in makeup to an on-road electric highway application.

During the visit, ABB highlighted how its solution had been customised and tweaked to work within the regulations and safety standards in Sweden, as well as Boliden’s own site requirements.

Epiroc also showcased how its battery-electric Minetruck MT42 SG has been adapted to work on trolley; the most obvious adaptation being the use of three battery subpacks as opposed to the standard five subpacks the battery-only machine is normally equipped with. The removal of 40% of battery power was justified to make room for the on-board DC-DC converter, as well as the reduction in power required to operate on the trolley line – as is currently envisaged, the trucks will only run on battery power alone for a circa-0.9 km stretch of the 5.6-km ramp.

Franck Boudreault, Epiroc’s Underground Application Expert Electrification, remarked on the economic benefits of running off grid-backed trolley power, compared with battery power alone. The OEM’s modelling also indicated the batteries on board would benefit from a substantial uplift in life due to the comparatively “light duty” application they would have while on trolley. This increased longevity would translate to reduced operating costs over the mine’s lifetime.

BEV loader first

As if the battery-trolley first was not enough for one project, Rävliden also became the first mine to automate stope loading with a battery-electric LHD – the Epiroc Scooptram ST18 SG – late last year at Rävliden. This is on top of commissioning ABC Total on an Epiroc Simba M6 longhole production rig at the operation. ABC Total allows for a full round of holes to be drilled automatically, according to Epiroc.

The miner’s ambitions go beyond this, though, with plans to automate the fleet of Minetruck MT42 SG Trolley trucks running on the ramp. The ‘concrete’ nature of these plans is evidenced by the fact Boliden has already built a loading station adapted for automation underground at Rävliden, as well as the moves to install an above-ground remote operations station later.

There is plenty more to this mine, which produced first concentrate last year, than ramp haulage.

The circa-$120 million investment also covers an underground crusher – a Metso Nordberg® C160 jaw crusher – a ventilation plant built with heat exchangers for increased efficiency and sustainability, a truck loading station, workshop and pumping stations.

The automated loaders carry blasted material from the stopes to either ore passes or loading pockets. Material is either directly loaded from the bottom of ore passes into the crusher at -750 m or by using MT42 SG trucks to transport material from loading pockets to the crusher. From the crusher, the material is transported by conveyors to loading chutes. These chutes feed crushed ore to the MT42 SG Trolley trucks, which move up the ramp and dump on surface. Ore is then trucked circa-90 km to the Boliden Area Operations Process Plant for beneficiation by flotation, before further processing the concentrate to a final product at the Rönnskär smelter, 65 km away.

The electrical infrastructure to support a complete fleet of electric vehicles and mobile equipment is also part of this, as Westerlund and his colleague Frida Pettersson (Project Manager at Rävliden) confirmed.

In a brief presentation on these plans, Westerlund outlined a fleet that included three battery-electric LHDs, three battery-electric trucks, four battery-trolley trucks, two “construction” battery-electric trucks, two electric light loaders and 12 “mining machines” that are also due to be battery-electric.

Battery-powered machines already ordered and/or delivered include two Epiroc Boomer E20 SG Battery drills, two Epiroc Boltec E10 SG Battery bolters, one Jama battery-powered SBU8000E underground scaler (using an Epiroc battery solution underpinned by Northvolt batteries), three Epiroc Scooptram ST18 SG LHDs, two MT42 SG trucks and the four MT42 SG Trolley trucks.

Westerlund admitted question marks remained over whether Rävliden would be able to source a full-electric fleet in the next few years, explaining that the company has had to employ diesel equipment where it cannot currently obtain the ‘green’ alternatives. He was hopeful there would be a proliferation of battery-electric integrated tool carriers in the near term – outside of the diesel-to-battery conversions available in relatively small quantities in Australia – as well as battery-electric material transport trucks from the likes of Scania. He also saw mass produced battery-electric pick-ups coming.

Haulage to surface and underground load and haul activities represent over 85% of diesel and CO2 emissions at the project, according to Westerlund, meaning the big emission wins are within reach.

All these machines could come together for a mixed battery-electric autonomy first, with Epiroc the likely integrator in this scenario – similar to what the OEM has achieved with a mainly diesel-powered fleet at the Cadia operation, in Australia, in partnership with MacLean.

This is the current plan, but there is some flexibility being built into the mining operations at Rävliden. Westerlund and Pettersson, for instance, said the ventilation plant had been sized for a bigger operation, with expectations that exploration will reveal more resources to justify higher mining rates.

Commercial appeal

With Boliden committing to this battery-trolley haulage scenario, it opens the question: how big a market is there for such a solution going forward?

There were several attendees from major and mid-tier mining companies on this trip, indicating interest is high. At least one mining contractor and some smaller consulting/engineering companies also joined the delegation in Sweden.

There were questions put to Westerlund and Pettersson from this community about whether the same throughput could be achieved via a hoisting operation. In response, Westerlund referred to the obvious fact that the planned haulage route meant the company could reuse the current industrial area and leave a very limited footprint on surface at Rävliden.

A Jama battery-powered SBU8000E underground scaler in operation

The battery-only haulage question came up too, but the 1:7 average incline of the ramp would likely require a significant number of battery swaps and/or charges during normal operation.

Boliden is in a very good position to enact this plan, being blessed with a significant amount of renewable power at Rävliden, expertise with battery-electric machines and the required electrical infrastructure thanks to previous trials and vehicle acquisitions, previous experience of underground trolley via Kiruna truck deployments at Kristineberg and elsewhere, and confidence in the expansion of its orebody.

While not in a unique position, there are only a few companies and operations that have all these factors going for them.

This will inevitably play into Epiroc’s plan to commercialise the MT42 SG Trolley system, and ABB’s own supporting electric infrastructure.

Boudreault said there were several criteria Epiroc wanted to tick off with the test track at Rävliden to highlight the commercial business case, including:

  • Demonstrating the ability to manage energy in a smart way on trolley;
  • Benchmarking the cost per tonne of such an operation; and
  • Showcasing the potential productivity benefits.

“We very much see this proof of concept with Boliden as the ‘ice breaker’ in terms of battery-trolley haulage potential,” he said.

Those who visit the mine in 2025 will likely see the commercial operation of the 4.7-km trolley line, gaining an understanding that goes beyond the proof of concept, but Boudreault said the significant speed on ramp boost, improved cycle time and ability to deploy less trucks in such a haulage operation would prove enticing for starters.

“At the same time, we are aware that the right partners will be needed to make any new installation a success,” he explained, adding that ABB’s input may be sought again for such a deployment.

This is before considering the local electrical standards that such an operation would be guided by, plus any other safety-related regulations that would need consideration.

“All of these will be factored into trade-off studies that are specific to that operation and the company’s own requirements,” Boudreault said, adding that, on paper, an operation with a 5-10 year mine life was likely required to make a battery-trolley operation economically work.

Leading from the front

The involvement of Swedish innovation agency Vinnova and its initiative ‘Sustainable Industry’ – which includes some financing for the project – will undoubtedly have helped get such a project off the ground at Rävliden, yet don’t discount the ingredients Boliden can call on to create the ideal mix for such innovation.

More so than any other mining company, Boliden has integrated sustainability at every point of the supply chain.

It has been using an internal carbon price to make investment decisions at all its operations for over a decade; it has embedded recycling into its thinking, becoming one of the first miners to leverage smelting capacity to process such material; it has implemented nitrate-free and environmentally friendly explosives at some of its operations (Kankberg being one); and it has also embedded mill lining recycling into its activities at Aitik.

That’s before mentioning its feats in the mining equipment automation space, an arena the company feels will pair well with electrification to deliver more than the sum of their parts in the future.

Many of these feats have been facilitated by the renowned Nordic mining equipment, technology and service space, which has allowed the company to access and implement the solutions at a suitable pace.

Not all miners demand respect from their peers and stakeholders, and even fewer can claim to be ‘climate-friendly’. Boliden can argue it ticks both boxes.

Boliden, Hypex Bio inaugurate Sweden’s first nitrate-free explosives facility

Boliden has announced the introduction of nitrate-free, low-carbon explosive, developed through a collaboration between the mining company and Hypex Bio Explosives Technology.

This new technology not only reduces the mining industry’s CO2 footprint but also eliminates nitrogen pollution in soil and water, setting a new standard for sustainable blasting, Boliden says.

Hypex Bio’s patented explosive is a major innovation in commercial blasting – one of the most significant advancements since Alfred Nobel’s invention of dynamite over 150 years ago, the miner claims.

Back in March, Boliden announced it had become the first mining operator to sign an agreement for the production and delivery of a newly developed explosive from Hypex Bio with significantly improved environmental and climate performance. In the process, the company’s need for nitrogen treatment of water is being reduced and its climate performance is improving by around 400 t of CO2 per year, it explained.

On September 16, Boliden and Hypex Bio officially inaugurated Sweden’s first facility for manufacturing nitrate-free, climate-friendly explosives at the Kankberg mine outside Boliden.

This facility represents a new standard for the next generation of explosives, thanks to a successful partnership between the two Swedish companies committed to driving the future of sustainable and climate-resilient mining, both locally and globally.

“With a production capacity of 270 t per week, this explosive already exceeds Boliden’s current operational needs, marking a major leap in the green transition of mining operations,” Boliden says. “As we continue striving to become the world’s most climate-friendly metals supplier, this technology will play a vital role in reducing our environmental impact, both in Sweden and globally.”

ABB’s Dittakavi looks forward to more Real Progress with eMine ecosystem

Three years after the launch of ABB’s eMine™ ecosystem, the results speak for themselves: six operational trolley systems, a proven fast charging system and numerous project leads in the offing.

Speaking to Ratna Kanth Dittakavi, Global eMine Sales Manager, it is clear the best is still yet to come from the ABB business line.

In the lead-up to a showcase of the company’s underground trolley capabilities at Boliden’s Rävliden mine in northern Sweden this week, Dittakavi was effusive about the company’s prospects – both with OEMs and mining companies.

He was able to share such foresight with numerous eMine consultative studies ongoing.

“We have about a dozen of these studies going on at the moment,” he told IM. “These are all in various stages of development – from prefeasibility study and feasibility, through to engineering.”

Such studies underpin the company’s eMine execution strategy, considering all electrification options for clients and coming up with a tailored, technology-agnostic plan for the company.

ABB’s close ties with a growing number of OEMs and suppliers – it recently signed a collaborative agreement with Komatsu, for example – plus its ability to carry out the majority of electrification, automation and digital work on its own, differentiates this offering from the standard engineering or consulting services available to mining companies or contractors.

“When we come up with an electrification plan for a client, say, 3-5 years ahead of production with 10-15% contingencies, we have to execute it for them,” Dittakavi says. “We don’t devise these studies for someone else to enact them. It goes beyond project execution too, as we’re often supporting the electrical infrastructure on site throughout the life of the mine.”

Early engagement is the key to being able to devise these strategies with clients, according to Dittakavi, however when looking at the six trolley projects the company is currently able to talk about – Aitik, Aitik Extension, the second trolley line at Kevitsa, Copper Mountain, Los Pelambres and Rävliden – he admits that the engagement timeframe hasn’t always been consistent.

“Just as we look to come up with a tailored solution for the client depending on their green energy inputs, site-wide infrastructure and load and haul fleet, for example, we also have to work within the constraints of the project timelines we are given,” he says.

Outside of the existing trolley projects the company is working on – including the 800-m test track at Rävliden – ABB is also working on a Robot Automated Connection Device (ACD) to charge future battery-electric trucks. This is planned to be a fully automated interoperable connection device working in tandem with the ABB eMine Fast Charge solution.

The ACD is set to be showcased in some form at next month’s MINExpo INTERNATIONAL 2024 event in Las Vegas IM understands, with a prototype also set to arrive at Boliden’s Aitik mine shortly for testing with a “dummy plug” connection, Jonas Ranggård, Program Manager at Boliden Mines, confirmed this week.

ABB and real progress in mine electrification with eMine™ portfolio

For more than 130 years, ABB has been embedded in industries where emissions are hard to abate and where alternative solutions are either unavailable or difficult to practically implement. The same is true today with mining, with ABB showcasing that the power of bold ideas and pioneering technologies can overcome challenges the sector is experiencing.

In the mining industry, ABB says ‘Real Progress’ means helping customers through their energy transition, with integrated electrification, automation and digital, combined with world-class technologies for hoisting and grinding. The ABB eMine™ portfolio of solutions is one example, empowering companies to convert fossil fuel-reliant mines to all-electric.

In Sweden and Canada, ABB’s eMine Trolley System has been in operation at large, open-pit mines where diesel trucks are retrofitted to run on electric trolley lines while transporting ore. Copper Mountain Mining Corporation (now part of Hudbay Minerals) has reported that the electrified solution has resulted in a 90% reduction in carbon emissions for the electrified trucks running on trolley, compared with the diesel-powered trucks, while they also run at twice the speed.

Also in Canada, the eMine FastCharge high-power electric charging solution for haul trucks is being put through its paces, with the flexible and fully automated solution designed for the harshest mining environments.

IM spoke with ABB’s Mehrzad Ashnagaran, Global Product Line Manager Electrification, and Ratna Kanth Dittakavi, Global eMine Sales Manager, to find out more about the company’s electrification advances ahead of their appearances at The Electric Mine 2024, in Perth, Western Australia, taking place at the Crown Perth Complex, on May 21-23.

IM: It’s been almost three years since ABB launched its eMine portfolio of solutions. How would you say the mining industry’s reception to electrifying their operations has changed over this timeframe?

MA and RKD: At the time ABB eMine™ was launched in 2021, conversation around integrated electrification and automation with multiple vendors working together was in isolated pockets around the globe. Since then, we can say that from a stage of infancy mining operators and their industry partners have grown. The path of technology development and implementation has footprints along it as these collaborators have increased interest and uptake. Electric-driven equipment and electrical infrastructure is now being put in place in certain geographies – in Europe and North America, for example, where access to greener forms of energy is more obvious. Moreover, the industry as a whole is widely agreed that electric systems, combining automated elements, smart solutions and user-friendly interfacing, are the future. It will take time, but legislation and policies from governments are moving in the right direction to support electrification. ABB has seen this first hand through our recent invite on to European Association of Mining Industries (Euromines) committees to support with the promotion and consideration of responsible industry practices.

IM: Over that same timeframe, how has the eMine portfolio of solutions evolved? Have you felt the need to accelerate your solution development to serve the requirements of the industry?

MA and RKD: As well as being a portfolio of solutions, ABB eMine™ is an overall approach and way thinking, and it has been recognized as such. It has a purpose to make the all-electric mine possible and a route to do this with proven methods, electrification and automation systems from mine to port. But, focusing on the technologies in the nearly three years since launch, we have continued to drive, and at times accelerate, developments alongside close partners and customers. Take, for example, eMine™ Trolley System, which has moved on from only being a solution for large ultra-class diesel haul trucks in open-pit mines. It has recently been engineered for use in underground mines in tandem with battery-electric trolley trucks – bringing part of the all-electric mine to life in reality with Swedish partners Boliden and Epiroc. Meanwhile, our ABB engineers have developed eMine™ FastCharge as an engineered solution for customers. The power capacity of the fully automated charging system is now being steadily increased through research and development with the aim of being compatible with some of the world’s largest trucks.

IM: Are you seeing more mining companies opening to collaboration to solve some of the tricker electrification challenges they facing? Is ABB doing the same?

MA and RKD: Electrification has enormous potential for the mining industry in terms of operational cost savings, future-ready mine designs and shoring up energy supplies in the face of uncertainty around global supply chain issues for fossil fuels. An electric mine looks very different to a traditional mine on paper and over the landscape, so ABB has found that mining companies are looking to us from the earliest stages of planning. If, together, we have a chance to think about mine power requirements, ehouses and substations, truck routes, ramps and inclines, stoppages where charging could be carried out, people and equipment movements, it has a better result than trying to force or retrofit technologies. Once a mine is laid out, it’s not easy to change. eMine has been a door opener to effective conversations around not only electrification, but automation, digital solutions and service because the best planning is holistic. ABB can help customers to find out what will fit to the mine operations, often with inputs from key technology partners. In terms of electrical technology, it could be conveyor versus haul truck, or hoist versus conveyor and trucks. The combinations have to be investigated and agreed for the specific mine operation.

IM: Would you say the collaborations you have in place with Antofagasta Minerals and Boliden/Epiroc – which will be showcased at The Electric Mine 2024 – are representative of this shift in mindset?

MA and RKD: When we speak about customers in as diverse regions as northern Europe and South America, there are significant distinctions to be made, of course, but we have seen that customers worldwide are taking on the challenge of electrification, using resources available to their regions and adapting technologies to suit their environments. It’s well-documented that Sweden is a technology leader in mining, with established use of hydro power and some of the most advanced electrification and automation embedded in their operations. The new developments with Boliden and Epiroc are one example of ABB’s involvement in continuing to push the boundaries alongside industry peers. Taking the challenges in South America, mining companies are often working with remote sites at high altitude that don’t have well-connected infrastructure or reliable electrical grids. As a technology provider we consider the specifics of each location, such as where the nearest medium voltage connection is or how we can support operators to make adjustments from the safety of operations centers far from harsh natural environments.

IM: More widely, how do you define ABB’s unique offering to the mining sector when it comes to electrification? Where is the company’s expertise and offering proving decisive on projects?

MA and RKD: In terms of heritage, ABB has more than 130 years of history in the electrification of mining, beginning when our company first electrified a mine hoist in Sweden in the 1890s. But, since then, ABB has passed on expertise in electrical engineering from generation to generation and has driven innovations and advancements. We use technologies as an enabler, but always with the awareness that change should be expected – every technology we are speaking about today is developing. Mining companies are basing their decarbonization initiatives, strategies and planning on the expectation that these solutions with acceptable technology readiness levels will be available in time aligned with their decarbonization goals and road map. Through early engagement and by working together on industry-agnostic, interoperable solutions that can be adapted in line with new technologies gives a level of peace of mind. We work with customers to deploy the best available and bring the future ecosystem today – combining electrification, automation and digitalization for the highest levels of productivity, safety and sustainability.

IM: In addition to what you have already discussed above, what can attendees of The Electric Mine 2024 look forward to hearing about next week?

MA and RKD: In a world first, ABB and Epiroc, will take to the stage to jointly share the background, technical details and vision from the implementation of their underground trolley system for battery-electric haul trucks at Boliden’s Kristineberg mine in Sweden. Since announcing the technology milestone this year, we’ve engaged in important industry conversations signalling that this is just the start of a new era. Together with Franck Boudreault, Underground Application Expert – Electrification, Epiroc, I (Mehrzad) will speak on this exciting project. Further to this, we will share further details of decarbonisation in the all-important copper segment in South America, focusing on the role of collaboration in hitting net zero. Tomás Nass, Decarbonization Manager, Antofagasta Minerals, Chile, will host the presentation in partnership with myself (Ratna). Finally, Dr Fabiana Cavalcante, Global Head of Mobile e-Power, ABB Traction, is set to present a view on diesel to electric drivetrain conversion activity with Nuh Cement’s zero emission dump truck in Türkiye. The mining industry is ready for electrification and we look forward to engaging with contacts, colleagues and delegates at this major event.

ABB is a Gold Sponsor of The Electric Mine 2024, with the company having a major indoor display in the exhibition hall. Both Mehrzad Ashnagaran and Ratna Kanth Dittakavi will be on stage at the event as part of joint presentations during Day 1 of the event.

ABB on the final piece of the electrification puzzle

Every train, industrial, or transportation vehicle needs a unique traction powertrain for operation, with ABB, through its Traction division, holding a complete and flexible product portfolio that, it says, allows it to build the perfect electrification solution for operators to transition businesses to more sustainable and lower cost operations.

Each of these solutions can be tailored to customer requirements and the operating conditions of each vehicle that it powers, enabling maximum energy efficiency, zero carbon emissions and high reliability.

The company is able to leverage high-tech e-mobility and rail system traction converters, energy storage systems and electric vehicle charging solutions as part of its offering, complementing this with enhanced expertise to help accelerate the transition to all-electric operations.

One project where its impact has been felt is at Nuh Cement in Turkey where ABB is working jointly with the company to convert 10 mainly Euclid/Hitachi dump trucks with an average 160 ton capacity, which have completed their 30-year service life, from diesel engine power to electric.

This is one of the first mining truck battery conversion projects of its kind in the world and will be discussed in more detail during a presentation at The Electric Mine 2024.

Ahead of the event, taking place at the Crown Perth Complex, on May 21-23, we spoke with Fabiana Cavalcante, Head of Mobile e-Power at ABB, to find out more about the offering.

IM: ABB’s Traction division is working within a very competitive landscape when it comes to e-mobility in mining. What would you say are your unique selling points to the industry?

FC: We bring over 130 years of experience in mining electrification, combined with extensive expertise in electrification and charging infrastructure for cars, buses and trucks. This allows us to extend our capabilities to the final piece of the puzzle: electrifying mobile equipment.

Fabiana Cavalcante, Head of Mobile e-Power at ABB

Our journey began by utilising our unique knowledge in rail propulsion systems and adapting it to the harsh environment of mining. Our roots in electrifying the Swiss railway network over a century ago have established us as leaders in sustainable transportation solutions. We have translated this experience to increase energy efficiency, reliability and reduce emissions across rail networks, electric buses and other heavy vehicles. The building blocks of the technology are similar, making for a smooth transition.

Besides this, what truly sets us apart is our capacity to execute customised customer projects. Battery-electric propulsion requires more personalisation compared to diesel, and our history as an independent supplier has equipped us with the skills, mindset and a perfect portfolio of proven base components to adapt quickly and in larger quantities than any other company.

IM: You work with multiple OEMs and solution providers across the globe looking to electrify their operations. Are most of these companies looking to electrify their offerings during a similar timeframe?

FC: Many mining operators have ambitious sustainability targets, aiming to reduce their Scope 1 and 2 emissions by at least 30% by 2030. By 2050, many operators aim to achieve net-zero emissions, and the only path to that is by electrifying their mining vehicle fleets. If every truck in every mine were electrified, we could remove 198,000 tons of CO2 from the atmosphere each day. Mining operators and OEMs recognise the potential to minimise their carbon footprint, and while this transition won’t happen overnight, we’re excited to partner with them and guide them on their electric journey.

IM: How often are you interacting directly with the operators during these types of projects? At this stage, is it often a collaboration between ABB, the OEM and the client?

FC: The level of interaction varies from project to project. In some cases, we have limited direct engagement with the mine operator, while in others, we are heavily involved. A recent example is our collaboration with Boliden and Epiroc, where we worked together to create the first battery-electric trolley truck system for underground mining. This close partnership was crucial to bringing this innovative project to life.

IM: In this regard, how does your work with Nuh Cement on converting its diesel powered fleet to electric power stand out from the work you normally carry out? Why is Nuh Cement able to collaborate directly with ABB on such a project?

FC: Nuh Cement approached us with the goal of converting their existing mining fleet of Euclid/Hitachi dump trucks to electric power and we officially began the project in 2022. We have vast experience in retrofitting vehicles for the rail business and we followed the same approach and procedures for the haul trucks.

The steep ramps with up to 20% gradient required us to pay close attention to ensure that the electric trucks could meet the expected performance and efficiency levels. This involved intense collaboration between both parties to translate simulations into practical, real-world solutions. Working closely with Nuh Cement, we tailored our solutions to fit their specific operational requirements and made sure our technologies aligned with their vision for a sustainable future. We hope many more mine operators will soon start to electrify their fleet and we’re excited to closely partner with them throughout their journey.

IM: Are you able to provide a sneak preview of what you will present at The Electric Mine 2024 in Perth about the Nuh Cement project? How has this project advanced since it was announced back in 2022?

FC: I’m excited to share the results of our groundbreaking collaboration with Nuh Cement at the event. Our partnership led to the successful electrification of a haul truck, demonstrating ABB’s ability to retrofit diesel-powered vehicles into fully electric ones – a milestone with significant implications for the mining industry. This transformation of a 30-year-old vehicle into a net-zero haul truck sets a new standard for sustainable mining practices worldwide.

Additionally, attendees will hear from Nuh Cement’s CEO, Kamil Gökhan Bozkurt, who will provide insights into this key project.

IM: In addition to what you have already discussed above, what can attendees of The Electric Mine 2024 look forward to hearing about next month?

FC: I encourage everyone to visit our team at booth 58 during the conference. Attendees will have the chance to explore our latest technology and innovations, including a preview of our new energy storage system, which offers exceptional lifespan, power and safety. We look forward to seeing you all there!

ABB is a Gold Sponsor of The Electric Mine 2024, with the company having a major indoor display in the exhibition hall. Fabiana Cavalcante will be on stage at the event presenting, ‘Powering progress: ABB and Nuh Cement’s zero emission dump truck’ during Day 1 of the event.

Boliden selects Radtonics industrial 5G network as comms backbone for Garpenberg automation advances

Boliden has entered into an agreement with Radtonics, regarding the creation of a private industrial 5G network at its Garpenberg mine, in Sweden.

Among other things, the private 5G network will play an important role as a communication channel in a project for autonomous transport initiated at the mine.

Boliden is working strategically to use modern technology that automates processes, increases operational reliability and lays the foundation for long-term sustainable mining operations, Radtronics says. By implementing Radtonics’ industrial 5G network, the company adds an important component to that strategy.

Boliden chose Radtonics after a procurement process where several 4G and 5G options were evaluated. In the end, it was Radtonics’ solution for private industrial 5G networks that best met Boliden’s stringent requirements, the company says.

With Radtonic’s solution, Boliden Garpenberg gets its own private network that is both easy and flexible to implement. A private 5G network provides better transparency in the network and facilitates monitoring and data utilisation, according to Radtonics.

Radtonics is a Swedish company with global ambitions that has developed a unique solution for private industrial networks for 5G. With its technology, the company develops and builds high-quality industrial networks in a simple, automated and cost-effective way. The agreement with Boliden is another important strategic step in the company’s expansion.

Patric Lind, CEO and co-founder of Radtonics, said: “The fact that Boliden chooses Radtonics as its industrial 5G partner in this strategically important project is a confirmation that our technology and knowledge meet the industry’s requirements for robustness, reliability and innovation.”

Rio Tinto backs BEV use at Kennecott Underground with growing Sandvik fleet

Rio Tinto is progressing its mobile equipment electrification move at the Kennecott underground operation near Salt Lake City, Utah, having transitioned from using Sandvik Mining & Rock Solutions battery-electric loaders and trucks in a proof of concept to commercially deploying Sandvik battery-electric TH550B trucks and a Sandvik LH518iB loader.

Just last year, Rio Tinto approved $498 million of funding to deliver underground development and infrastructure for an area known as the North Rim Skarn (NRS). Production from the NRS is due to commence this year and is expected to ramp up over two years, to deliver around 70,000 tonnes of additional mined copper over the next 10 years alongside open-pit operations at Kennecott.

This followed a September 2022 announcement where Rio Tinto approved development capital totalling $55 million to start underground mining in an area known as the Lower Commercial Skarn (LCS) at Kennecott. Underground mining within LCS started in February 2023 and is expected to deliver a total of around 30,000 tonnes of additional mined copper through the period to 2028.

These two investments will support Kennecott in building a world-class underground mine which will leverage battery-electric vehicle (BEV) technology, following a trial with Sandvik equipment in 2022 involving an LH518B loader and Z50 truck.

The first LH518iB loader in North America has just been delivered to site, with the automation-capable vehicle equipped with Sandvik’s patented self-swapping battery system, including the AutoSwap and AutoConnect functions, to minimise infrastructure needs and enable the loader to return to operation significantly sooner than ‘fast-charge’ mining BEVs, Sandvik claims.

Since launching the vehicle in March 2023, Sandvik has confirmed orders or made deliveries of the LH518iB to operations owned by LKAB, Boliden,Torex Gold, Foran Mining, Rana Gruber and Byrnecut.

Rio Tinto will complement these machines with a fleet of Sandvik TH550Bs, some of which are already operating on site. This 50-t payload truck combine Sandvik’s 50 years of experience in developing loaders and trucks with Artisan™’s innovative electric drivelines and battery packs. The electric drivetrain delivers 560 kW of power and 6,000 Nm of total torque output, allowing for higher ramp speeds for shorter cycle times and an efficient ore moving process, according to the OEM. All of this comes with zero emissions.

They also come with AutoSwap and AutoConnect functions that Sandvik has refined for battery swap processes that take only a few minutes.

Rio Tinto has previously stated on battery-electric vehicle use: “BEVs create a safer and healthier workplace for employees underground, increase the productivity of the mine and reduce emissions from operations.”

Boliden to implement Hypex Bio climate-friendly explosives at Kankberg mine

Boliden says it has become the first mining operator to sign an agreement for the production and delivery of a newly developed explosive from Hypex Bio with significantly improved environmental and climate performance.

In the process, the company’s need for nitrogen treatment of water is being reduced and its climate performance is improving by around 400 t of CO2 per year, it says.

Peter Bergman, General Manager of the Boliden Area, said: “For us, it is important to be part of technology development in many areas and, when it is successful, we also want to be early with implementation. Together with the electrification of transport and other machines, this means another important step towards being able to conduct mining operations that are, in principle, fossil-free.”

The agreement with the Swedish explosives supplier Hypex Bio is for the production and delivery of nitrate-free and environmentally friendly explosives to Kankbergsgruvan, Boliden. Boliden and Hypex will cooperate on the production and delivery of nitrate-free and environmentally friendly explosives to the Kankberg mine, which includes the establishment of a production facility at the mine as well as a delivery and service agreement.

The supply and service agreement for Hypex’s explosives solution spans five years, starting in 2024. The production quantity is expected to amount to 400-450 t and, thus, largely meet the Kankberg mine’s annual needs. In addition to the fact that the explosive drastically reduces the need for nitrogen treatment of water, the climate impact is reduced by approximately 400 t of CO2 per year (Scope 3), Boliden added.

The collaboration between Hypex Bio and Boliden has been ongoing since 2020, where the nitrate-free explosive has been developed and tested in the Kankberg mine. The technology has proven to meet Boliden’s requirements for safety, performance, environment and reduced carbon dioxide emissions. Tests have also been carried out in the Garpenberg mine and are to be started in the Aitik copper mine, the company says.

Back in October, Omnia Holdings announced a strategic partnership with Hypex Bio and the acquisition of a minority equity stake in the company.
