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.

Sandvik looks to shape the surface drilling electrification conversation

“We are showing what technology can do today.”

These were the words Mats Eriksson, President of Sandvik Mining and Rock Solutions, during the Capital Markets Day in Tampere, Finland, last week when describing the launch of Sandvik’s latest battery-electric concept surface drill rig.

This rig is representative of more than just technological advances in the mining industry, also acting as a tangible example of Sandvik’s efforts to become a leader in the surface drilling space.

It has been four years since Sandvik announced this ambition, with the company having made significant headway on achieving this goal.

Sandvik doubled its order intake for rotary drills from 2019 to 2022. Over this three-year period, the company launched the Leopard™ DI650i down-the-hole (DTH) drill rig to support fully autonomous drilling operations and went on to capture major autonomous drilling contracts in Latin America, Australia and Finland.

The OEM is looking to at least double its surface mining revenue from 2022 to 2028. Key contracts in 2023 from Boliden and MACA have already provided early positive momentum towards such a goal.

There is potential for Sandvik to steal a march on its competitors in this space – companies who have already been able to automate the largest blasthole drills in key markets in the Americas and Australia – by leveraging the electrification expertise it has built up underground.

This was highlighted by Eriksson last week and was reiterated further when IM spoke to the company’s experts in Tampere in front of the second battery-electric surface concept rig.

The concept vehicle is the first in its size class, capable of drilling DTH holes up to 229 mm in diameter and blending the autonomy of battery with the continuous endurance of power cable, Sandvik says.

Flexibility and optionality are the name of the game, with the rig equipped with a battery able to carry out seven hours of tramming or one hour of drilling based on Sandvik research, plus plug into electrical infrastructure with a  37-mm diameter, 180-m-long tethered cable.

Lauri Laihanen, Vice President, R&D, Surface Drilling Division, Sandvik Mining and Rock Solutions, told IM at the Sandvik Capital Markets Day event last week: “The main benefit of this battery-electric solution is the ability to tram independently for up to seven hours.

“When you need to move the rig after drilling a certain portion of the pit ahead of blasting, you can disconnect the cable and tram the rig away from the pit independently without worrying about managing the cable logistics. Then, when you have carried out the blasting and explosives loading process and are ready for the next drilling sequence, you can tram back without recharging in between.”

Petri Virrankoski, President of the Surface Drilling Division, added: “The application where these drills are used is somewhat different to rotary drills. To a degree, they are used in production drilling, but in a very dynamic way – carrying out pre-splits or blasthole patterns on smaller benches, for example.

“They need to manoeuvre around more, so there are more demands placed on them from a flexibility and cable management perspective.”

There are other potential benefits Laihanen talks up – the ability to carry on drilling or tramming during “black outs” and, on mine sites where cable-electric equipment is already used, connect the rig to the grid after diesel-electric blasthole drills and cable shovels have started up (to avoid power surges).

“For some of our frontrunner customers that have already adopted electrification on surface and have the infrastructure in place, they would only need to add one transformer to lower the voltage level from what their larger pieces of equipment are working off to start using this rig for drilling and tramming,” he added.

This type of talk – more practical than conceptual – is representative of Sandvik ‘making the shift’ when it comes to electrification in surface mining.

It has only been just over a year since the company unveiled its first electric concept rig, based off a much smaller top hammer drill rig meant for urban construction, but the understanding of what it may take to electrify these large rigs has grown tremendously.

“From a technology development and demonstration point of view, it is crucial to understand the framework that you have from the lower and upper end of the drilling portfolio,” Laihanen said. “This helps you track it with the customer base and finalise your productisation plan to hit that 2030 goal of having an electrified offering for the whole range.”

Eriksson says the company is confident in being able to offer electric surface drilling products across its range by 2030, with Sandvik’s continued advances in underground mine electrification spurring this on.

It is worth, therefore, noting some of the numbers that came out of the Capital Markets Day from the underground load and haul division.

Brian Huff, Vice President of New Technologies for the Load and Haul Division within Sandvik Mining and Rock Solutions, said the company had won more than 75% of the tenders it had been involved in from January-October this year, with more than 15% of the company’s load and haul order intake over this period representing battery-electric equipment.

One can also add sales of the company’s underground battery-electric drills, which started to be offered to the market from 2016, to these numbers.

The company’s Test Mine in Tampere, which IM visited last week, has played a key role in this growing Sandvik underground battery-electric population, and the recent announcement that Sandvik will look to replicate this on surface with the Sandvik Test Pit – some 40 km away – is another indicator of how serious the company is about becoming an open-pit drilling major.

Virrankoski explained: “If you look at the peak capabilities that have enabled us the successes underground, one of these is the Test Mine. This has been helpful for testing and developing not only the drill rigs, but also tooling, digital tools, automation, rock drills, etc.

“It became pretty clear about four years ago that we needed a similar capability for surface.”

This location just outside of Tampere was chosen due to the “good rock” availability, the ability to offer significant scale where the company could test out all boom and rotary drill rigs up to the DR413 class at the same time as providing customer showcases both on electrification and automation, the ability to cross-fertilise underground learnings from the existing Test Mine with surface drilling developments, and the continued development of existing and new Sandvik surface mining engineers.

The Sandvik Test Pit, which has previously served as a quarry, will be developed by its own drilling plan

The company already has multiple rigs, both boom and rotary, at the site – which is still being setup for testing – with the new electric concept rig expected to soon join it.

“The next action after that is to begin customer trials next year,” Laihanen said. “We have had preliminary discussions with several customers, but we need to finalise our own internal development testing before locking in these trials.”

This is indicative of the emphasis the company is placing on surface mining and the opportunity it has to shape the battery-electric conversation in the surface drilling space.

“For us, it is important to have a physical specimen to have these conversations with customers,” Laihanen said. “When you have something available, it makes the conversation around capabilities and limitations a lot easier, taking these discussions to a whole new level.”

Virrankoski added: “This will lead to a conversation around maintenance processes, the skills requirements, the service models, etc.

“Having a machine that can play in a real-life sandbox is very different to showing a model on a screen.”

Sandvik has laid its surface drilling marker down. The market will now decide if this is the direction it wants to move in.

Boliden introduces ‘sustainable’ game-changer: Low-Carbon Sulphuric Acid

Sweden-based Boliden has taken what it says is a significant step toward a greener future with the launch of Low-Carbon Sulphuric Acid.

The new product increases Boliden’s collection of low-carbon offerings, joining the likes of Low-Carbon Zinc, Recycled Zinc, Low-Carbon Copper and Recycled Copper within the Green Transition Metals portfolio.

Sven Hjelmstedt, Director Sales at Boliden, says: “Our long-term work with sustainability empowers Boliden and our clients to create products with significantly lower carbon footprints. We support our clients’ sustainability goals and support them in reducing their Scope 3 emissions, contributing to an improved environmental performance for their industries.”

Low-Carbon Sulphuric Acid showcases Boliden’s strong commitment to sustainability, the company says. It has a minimal carbon footprint, measuring less than 25 kg of CO2 per tonne – well below the EU average.

What sets Boliden apart is that the company produces sulphuric acid from the same raw materials used to produce metals using a green energy mix, making it highly resource and CO₂ efficient, compared with the majority of global sulphuric acid production, which mainly relies on raw materials from oil refining.

Hjelmstedt added: “For clients, the benefits are twofold. Low-Carbon Sulphuric Acid helps reduce their carbon footprints while providing a sustainable product independent of fossil fuels. This is particularly valuable for industries reliant on sulphuric acid such as the global fertiliser and wood-based product industries.”

Boliden looks to strengthen biodiversity ties with Sarkanenä Sustainability Park near Aitik

In order to strengthen biodiversity and create accessible nature experiences for the public, Boliden has today inaugurated the Sarkanenä Sustainability Park close to its Aitik mine in Sweden.

The company’s aim is for additional sustainability parks to be introduced in connection with active or decommissioned sites, it says.

Åsa Jackson, Executive Vice President People and Sustainability at Boliden, said: “Mines inevitably have an impact on the environment and the local community in which mining takes place. However, by restoring the land or setting aside other land and initiating efforts to promote biodiversity, we can strengthen the overall natural values and contribute to long-term solutions for both ourselves and others.”

Boliden’s sustainability parks are areas within our land holdings consisting of forest land, decommissioned sites or land adjacent to active sites that can be opened to the public. The sustainability parks reflect the conditions at the site in question and will demonstrate the site’s history and Boliden’s association with it, historically, today and in the future, the company said.

A meeting place protected from weather will be available at all parks, along with nature experiences in the form of trails, playful elements, activities and more to learn about biodiversity. The information provided is also based on ecological, economic, socio-cultural and legal aspects, such as the natural values associated with the site and how these can be recreated and strengthened.

Sarkanenä Sustainability Park is located about 10 km south of Gällivare along the road to Nattavaara and includes, in addition to other features, a circa-2 km hiking trail with an experience trail.

Volvo and Boliden partner on autonomous transport and load solutions

Volvo Autonomous Solutions (VAS) and Boliden have entered into a long-term collaboration that will see the pair take on various projects, the first of which will be the implementation of an autonomous transport and load solution for a dam project in Garpenberg, Sweden.

The MoU also includes an agreement by VAS to deliver an autonomous transport solution that will move rock fill from an on-site quarry.

As a part of the implementation, VAS will deliver a complete autonomous transport solution that includes vehicles, hardware, software, control room, repair and maintenance, and training. The solution will be based on the OEM’s in-house developed virtual driver and the Volvo Trucks’ premium truck range.

To prepare the site for the implementation of autonomous trucks, Boliden will adapt its operations and build the necessary infrastructure.

Nils Jaeger, President of Volvo Autonomous Solutions, said: “Whether it is removing people from hazardous environments, 24/7 operations unencumbered by working hours or reducing emissions through better utilisation of resources and assets – autonomy offers several benefits that can help the mining and quarrying industries address its most pressing challenges. We are excited to partner with Boliden and support their journey towards a future where autonomous vehicles and humans work side by side to make Boliden’s operations safer, more efficient and sustainable.”

Mikael Staffas, President and CEO of Boliden, said: “Autonomous solutions benefit both safety and productivity. The partnership with VAS is therefore of great strategic importance and we are of course delighted with the project in Garpenberg already underway. Demand for base metals will increase going forward and sustainable as well as competitive solutions will be key in the value creation of mining.”

Think & Act Differently Cohort set to revolutionise in-situ recovery

The Think & Act Differently (TAD) incubator, powered by BHP, has announced its support for a new cohort that has come together to develop an innovative technology roadmap for in-situ and alternative extraction options, the company says, lower the impact of mining and processing.

In collaboration with its partner, Unearthed, the TAD Cohort was curated through a venture-style selection process, which also involved selection of members from the TAD Ecosystem.

This cohort is supported and funded by BHP, Boliden, Rio Tinto, South32 and IGO, as part of the TAD Collaboration that is commited to unlocking new technologies and reimagining lower impact mining and processing to find value in overlooked resources.

The TAD Cohort comprises a diverse group of companies ready to apply new ways of thinking to in-situ recovery. It includes:

  • Auric BioRecovery: using bio recovery processes to release metal from tailings;
  • Clean & Recover: ElectroClear recovery of water from acid mine drainage;

Boliden Garpenberg receives Sandvik’s first automation-ready battery-electric Toro LH518iB LHD

Boliden’s Garpenberg zinc operation in Sweden has taken delivery of Sandvik’s first Toro™ LH518iB with AutoMine® as part of a 12-month collaborative trial of the new automation-ready 18-tonne battery-electric loader.

Considered one of the most modern mining operations, Garpenberg is the world’s most productive underground zinc mine and Sweden’s oldest mining area still in operation. The mine is now set to become the first in Europe to trial a Sandvik battery-electric loader, the OEM says.

The Toro LH518iB will support Boliden’s efforts to improve sustainability by reducing greenhouse gas emissions underground. The company’s climate targets include a 40% reduction of absolute CO2 emissions in Scope 1 and 2 and 30% reduction of Scope 3 emissions by 2030.

Jenny Gotthardsson, Garpenberg’s General Manager, said: “We are proud to be recipients of the very first Toro LH518iB with AutoMine. The unit has already undergone extensive factory testing in Finland and we look forward to really putting it through its paces now in our operation. We’re on a journey to reduce fossil fuel usage and CO2 emissions and increase productivity, and we are happy to work towards these goals with long-time partner Sandvik.”

The Toro LH518iB marries battery-electric and automation technologies. Building on the predecessor Sandvik LH518B, the Toro LH518iB features several design updates and significantly improved field serviceability. The latest version of Sandvik’s intelligent control system enables AutoMine readiness, and AutoMine compatibility will be available for Garpenberg’s Toro LH518iB in the March quarter of 2024.

The Toro LH518iB has dimensions equivalent to the 14-t size class, enabling it to fit in a 4.5-by-4.5-m tunnel. Its ground-up design, powerful electric motors and innovative electric driveline result in a compact size with higher payload capacity and increased visibility, Sandvik says.

Sandvik’s patented self-swapping battery system, including the AutoSwap and AutoConnect functions, minimises infrastructure needs and enables the loader to return to operation significantly sooner than ‘fast-charge’ mining BEVs, the company claims. The battery swap is performed by the loader itself, controlled by the operator in the cabin, without need for overhead cranes or forklifts.

Johanna Øygard, Territory Manager for North East Europe at Sandvik Mining and Rock Solutions, said: “We’re excited to see the productivity and sustainability benefits Garpenberg will gain from Toro LH518iB with AutoMine as we monitor the loader’s performance and production metrics over the next 12 months.”

In Mexico, Torex Gold is set to receive 11 Toro LH518iB battery-electric loaders as part of a 35-unit-strong hybrid fleet for its Media Luna project.

Sandvik autonomous surface drilling tech heading to Boliden’s Kevitsa mine

Boliden has selected Sandvik Mining and Rock Solutions to supply two Leopard™ DI650i down-the-hole (DTH) drill rigs and AutoMine® Surface Drilling systems, enabling fully autonomous surface drilling at its Kevitsa multi-metal mine in northern Finland, the OEM says.

The order also includes a five-year parts and services agreement and My Sandvik Onsite analytics for process optimisation. Delivery of the two Leopard DI650i drill rigs is scheduled during the September quarter.

“Boliden Kevitsa is committed to improving sustainability, productivity and safety by investing in the latest automated technologies,” Christian Bjorne, Vice President Sales Area Northern Europe at Sandvik Mining and Rock Solutions, said. “We look forward to continuing our technology cooperation and supporting Kevitsa in its journey to becoming an even more safe and productive mine through our drilling solutions.”

The Kevitsa open-pit mine represents one of the largest mines in Finland when it comes to excavation volume. Temperatures at the mine can drop below -30°C during the winter, and, with operations running 24/7, Kevitsa requires robust, proven technology. Sandvik and Boliden conducted comprehensive field tests over several months to prove the automated Sandvik drilling technology and performance. Technical support exceeded the mine’s expectations during the field tests, according to Sandvik.

Kevitsa will run the two Leopard DI650i DTH rigs using the AutoMine system from a remote control station near the drilling area or from mine control room. Boliden and Sandvik have an ongoing rock tools agreement at Kevitsa, including DTH hammers, bits, pipes and rock tools services. Sandvik on-site technicians will ensure support is available 365 days a year, maximising the drill rigs’ utilisation, productivity and reliability, it says.

AutoMine Surface Drilling is an autonomous solution for a wide range of Sandvik i-series surface drill rigs, designed to improve safety, reduce costs and increase productivity. Sandvik says it enables an operator to control multiple rigs remotely from a comfortable line-of-sight location or a control room – improving working conditions and safety.

Leopard DI650i drill rigs are equipped with iDrill technology, a scalable automation platform that supports fully autonomous operation and is designed to accelerate the production process. iDrill onboard automatics cover all steps of the drilling cycle from automated boom positioning, drilling and pipe handling to finishing the hole, and ensures consistent high-quality drilled holes, according to the OEM. These capabilities can be upgraded with more advanced modules such as single-rig or fleet remote control systems with AutoMine Surface Drilling.

Draslovka to bring glycine leaching expertise to OZ Minerals TAD incubator

Draslovka Holding a.s., a Czech family-owned global leader in cyanide-based specialty chemicals, says its glycine leaching technology has been selected to be part of the OZ Minerals’ Think & Act Differently (TAD) incubator and Waste-to-Value Challenge.

The latter challenge, announced back in December, sees Rio Tinto and Boliden working in collaboration with OZ Minerals to eliminate, minimise, reuse or find new value in mine tailings and ultimately reduce the global carbon footprint of the mining industry. Draslovka said: “The Waste-to-Value Challenge aims to unlock innovative technologies for managing tailings, helping the mining industry to reduce risk while extracting more of the materials the world needs from what was previously regarded as waste for the energy transition at large. Benefits that the initiative hopes to deliver include lower emissions and reduced waste.”

Draslovka offers a range of sustainable solutions to the global mining industry, and its glycine leaching technology (branded as its GlyLeach™ and GlyCat™ processes) represents the best environmentally-friendly alternative to traditional acid and cyanide leaching, according to the company. Due to its selectivity over gangue minerals and the recyclability of glycine, its use enables the recovery of both base and precious metals from lower-grade resources like tailings. This leads to a more sustainable production process and improved economics that are desperately needed to close the looming critical metal supply deficit.

Ivor Bryan, Draslovka’s Mining Innovation Director, said: “I am proud that Draslovka has been invited to participate in the Waste-to-Value Challenge with forward looking companies that understand the need to reimagine solutions for the mining industry. This aligns with our ambition to become the leading supplier for innovative and sustainable solutions for the wider mining industry.”

Speaking to IM on the sidelines of the recent Resourcing Tomorrow conference, in London, Bryan said the company was embarking on around 10 projects in the mining space, which will prove up the 3,500 hours of testing that has been conducted at MPS’ facilities in Perth, Western Australia.
