Cummins Inc says it has commissioned its diesel-hybrid solution in partnership with one of China’s leading rigid mining truck manufacturers, North Hauler Joint Stock Co., Ltd. (NHL), demonstrating progress in decarbonisation for industrial customers.

The hybrid NHL NTH260, a 220-t payload mining truck, rolled off the production line in January and is headed to Baiyun iron mine of Baogang Group, China, to begin field testing in March. As a power solutions provider, Cummins’ optimised hybrid system allows the truck engine to be downsized from the previous 2,500 horsepower QSK60 to the current 2,000 HP two-stage QSK50.

“We’re excited to share this significant milestone in our journey to advance bridge technologies and provide our mining customers with innovative, practical decarbonisation solutions,” Jenny Bush, Cummins Power Systems President, who joined key leaders from Cummins Power Systems China for the commissioning ceremony in the NHL industrial park in Bautou, China, said.

The truck is expected to provide a leading total cost of ownership based on initial cost advantages, fuel efficiency and extended service life of the engine, Cummins says. Improved fuel efficiency directly correlates to emissions and greenhouse gas reductions. Advanced hybrids have the potential to improve fuel efficiency up to 30% dependent on the mine profile and advanced battery technology and controls integration, according to the company.

Haiquan Guo, General Manager, NHL, said: “Our partnership with Cummins spans 40 years and advancing the hybridisation of our equipment is another demonstration of what we can accomplish together for the benefit of miners globally.”

NHL produces trucks with payload range from 35 t to 360 t, with Cummins as the standard engine configuration.

Molly Puga, Cummins Power Systems Executive Director of Strategy, Digital and Product Planning, added: “We are intent on enabling multiple pathways to carbon neutrality for industrial markets, including both first-fit and retrofit solutions. It’s partnerships with our customers like NHL and Baiyun iron mine that will accelerate product availability in the market and make both near- and long-term carbon reduction goals attainable.”

In 2023, Cummins announced approval of unblended renewable diesel use in all industrial high-horsepower engines.

Red Hawk Mining plots Blacksmith iron ore project haulage path with MGM Bulk

Uncategorised, , , , , , ,

Red Hawk Mining says it has entered into a strategic partnership with MGM Bulk Pty Ltd (MGM Bulk) for the haulage of iron ore from the company’s 100%-owned Blacksmith iron ore project, in Western Australia, to the Utah Point bulk handling facility in Port Hedland.

The haulage agreement enables Red Hawk and MGM Bulk to work collaboratively through the prefeasibility study (PFS) and definitive feasibility study (DFS) phases to develop and optimise the transport and logistics strategy, focusing on maximising productivity and reducing unit operating costs, the company says.

Following completion of the studies, MGM Bulk has the exclusive right to enter into a haulage services agreement on terms equivalent to those contained in the DFS. MGM Bulk will be responsible for providing a fleet of 150 t ultra-quad trucks and drivers plus associated loading and other equipment and infrastructure.

In a February presentation deck, Red Hawk Mining claimed over 200,000 m of drilling has defined the largest direct shipping ore (DSO) resource of any ASX-listed junior iron ore company (excluding magnetite) at Blacksmith with 174 Mt at 60% Fe. It said there was potential for thee project to be a long-term supplier of at least 3 Mt/y of 60.5% Fe DSO for over 20 years.

Red Hawk’s Managing Director, Steven Michael, said: “We are excited to work with the team at MGM Bulk to establish a haulage strategy optimised for the Blacksmith project. MGM Bulk’s operations in the Pilbara, centred around delivering iron ore into the Utah Point, are second to none. Their fleet size, quality, operational performance and safety record are critical factors in ensuring the success of the Blacksmith project.

“Our PFS team is working closely with MGM Bulk’s commercial and operations team to deliver operating and capital cost estimates with a high degree of certainty, which can easily be translated into an operational haulage contract.”

MGM Bulk’s CEO, Michael Giacci, added: “We are immensely proud to be forging a long-term partnership with Red Hawk Mining on the mine-to-port haulage solutions for their Blacksmith iron ore project.”

Grange Resources plots underground move at Savage River with electric mining equipment

A completed definitive feasibility study looking at the potential for underground mining below the North Pit and its integration with Grange Resources’ current open-pit mine at Savage River, in Tasmania, Australia, has showcased not only “robust financial outcomes”, but the potential for reducing carbon emissions by 80% at the mine, with the application of electric mining equipment and material handling systems underground.

This DFS development is in line with company’s environment, social and governance (ESG) initiatives to develop Green Pellet Production from the mine.

The study, according to Grange, presents a technically achievable and financially favourable underground mine at Savage River, with integration with the current open-pit mining operation to deliver “excellent” projected financial returns and sustains a mine life of 15 years. In line with this, the Savage River ore reserve is increasing by 12.5 Mt to 109 Mt with integration of the underground operation.

The new life-of-mine-plan will deliver a substantial reduction of 30% in operating costs with underground mining costs at an average of A$13/t ($8.4/t). It also delivers an internal rate of return of 34% based on an average product price of approximately A$177/t. The ore delivery of 64 Mt of ore produces 28 Mt of concentrate with an iron grade of over 66% over 15 years, Grange said.

A sub-level caving (SLC) transition mine to recover ore left in the walls of the North Pit provides early access to ore and contingency production during the establishment and ramp-up of the block cave mine. Over 2 km of exploration decline has been completed, which reduces the risk for many technical and cost elements of the project, with a further commitment for additional decline development and geotechnical investigation drives in 2024, the company said.

The prefeasibility study for this project considered several haulage options with associated underground configurations and underground and surface infrastructure. The underground crushing and inclined conveying option was chosen as the go forward case for DFS for the following reasons:

  • Significant reduction in emissions and ability to meet the long-term requirements of the updated Safeguard legislation;
  • Lower operating costs by the removal of production trucks and significant reduction in diesel;
  • Better future proofing with higher ore production levels possible allowing the option of higher concentrate production;
  • Improvement to the underground operating environment with improved air quality;
  • Increased options for future automation.

In addition, the single gyratory crusher that was presented in the prefeasibilty study has been replaced with two eccentric roll crushers, which provides redundancy in the material handling system. Crushed ore is transferred to the inclined conveyor system via apron feeder and conveyors.

Another PFS change saw the extraction level layout changed from ‘El Teniente’ diagonal to an offset herringbone to enable the use of tethered electric loaders and to mitigate effects of potential inrush events.

A board decision for Grange to move forward with execution planning and permitting will occur over 2024 with final construction decision in the second half of 2024, the company said.

The Government of Canada awards Rio Tinto’s IOC funding for decarbonisation project

Environmental, Mine operation news, Mining services, Steel and iron ore, Sustainable mining, , , , ,

The Government of Canada has awarded C$18.1 million ($13.4 million) from its Low Carbon Economy Fund to Rio Tinto’s Iron Ore Company of Canada (IOC) to support the decarbonisation of iron ore processing at its operations in Labrador West, the mining company says.

The funding will enable IOC to reduce the amount of heavy fuel oil consumed in the production of iron ore pellets and concentrate, according to Rio Tinto. The company will install an electric boiler to displace emissions from the usage of the heavy fuel oil boilers, as well as instrumentation and fuel-efficient burners to further reduce heavy fuel oil consumption from induration machines.

Over the lifetime of this project, IOC will see a cumulative reduction of about 2.2 Mt of greenhouse gas emissions.

Installation of the new equipment will begin in the June quarter of 2024 and is expected to be completed in the first half of 2025. The project will create more than 100 jobs during the construction and implementation stages in Labrador West.

IOC President and Chief Executive Officer, Mike McCann, said: “Rio Tinto IOC has a plan to decarbonise and continue producing some of the lowest carbon-intensity high-grade iron ore products in the world, right here in Canada. This project alone will eliminate approximately 9% of IOC’s greenhouse gas emissions. We look forward to collaborating with the Government of Canada and other partners towards our goal of achieving net zero emissions by 2050.”

Labrador Member of Parliament, Yvonne Jones, said: “By working with organisations across Canada, such as IOC, we can help the community save money on monthly operating costs and grow the economy, all while fighting climate change. Through the Low Carbon Economy Fund, the Government of Canada is partnering with climate leaders nationwide to cut emissions. I applaud the leadership shown by IOC for helping to keep our air clean and build resilient communities in Newfoundland and Labrador.”

The Government of Canada’s contribution represents approximately 25% of the total cost of the project, with IOC funding the remainder of the investment, Rio Tinto clarified.

BHP, BlueScope and Rio Tinto to investigate Australia low-carbon steelmaking options

Australia’s two largest iron ore producers, Rio Tinto and BHP, and its biggest steelmaker, BlueScope, have partnered in their efforts to accelerate the decarbonisation of steelmaking by agreeing to jointly investigate the development of the country’s first iron making electric smelting furnace (ESF) pilot plant.

Under a new framework agreement, the companies will consolidate the work each party has completed to date, leveraging both BHP’s and Rio Tinto’s deep knowledge of Pilbara iron ores with BlueScope’s operating experience in ESF technology.

The collaboration provides a platform to develop and potentially invest in a pilot facility and aims to demonstrate that production of molten iron from Pilbara ores is feasible using renewable power when combined with direct reduced iron (DRI) process technology, they said. If successful, it could help open a potential pathway to near-zero greenhouse gas emission-intensity operations for steelmakers that rely on Australian iron ore to meet global steel demand.

The parties will assess several locations in Australia for the proposed pilot facility, and will consider factors like supporting infrastructure, available workforce, access to target industry and supply chain partners, and suitability for operational trials. The prefeasibility study work program is expected to conclude at year-end. If approved, the pilot facility could be commissioned as early as 2027.

Rio Tinto Iron Ore Chief Executive, Simon Trott (right), said: “The carbon intensity of iron and steelmaking requires profound change to meet the needs of our planet and our climate objectives. We must find better ways to enable these materials to be made more sustainably through leveraging technology.

“We firmly believe the best way to tackle a challenge of this scale is through collaboration with industry and importantly this new agreement will leverage the more than two years of work we have already completed with BlueScope on this technology. We are excited to add this partnership to the suite of projects we have underway with our customers and suppliers to find better ways to accelerate their efforts to meet their decarbonisation targets.”

Incoming BHP Western Australia Iron Ore (WAIO) Asset President, Tim Day (left), said: “We are thrilled to partner with Rio Tinto and BlueScope to progress what we see as a potential breakthrough in reducing carbon emissions from steel production. Collaborations like this are so important for the success of these technologies and build on our work on blast furnace abatement projects, and our ongoing research and development projects with leading steelmakers, research institutes and technology providers around the world.

“Combining our expertise, we hope to help fast track near-zero emission-intensity pathways for steelmakers using Pilbara ores. Technology pathways compatible with renewable energy and scalable to the order of hundreds of millions of tonnes of steel production would be a major step forward in setting up Pilbara ores, and the world, for a low greenhouse gas emission future.”

BlueScope Chief Executive Australia, Tania Archibald (centre), said: “We have a clear vision for BlueScope in Australia as a vibrant, modern and sustainable manufacturer with a clear role to play in enabling Australia’s energy transition. Building a pathway to low emission-intensity iron and steelmaking in Australia is a key priority for our business. We’re excited to be partnering with Rio Tinto and BHP to explore the decarbonisation of the ironmaking process, and leverage the natural advantages of Australia – namely our iron ore resources and the abundant potential for renewable energy.

“We believe DRI is the most prospective technology to decarbonise our Australian business, and the development of ESF technology is key to unlocking Australia’s unique advantages in this decarbonisation journey – and, more importantly, has the potential for wider adaptation across the global steel industry. We believe that this collaboration where we can contribute BlueScope’s unique experience in operating an ESF will be key to cracking the code for Pilbara ores in low emission-intensity ironmaking.”

Mine operation news, Mining services, Steel and iron ore, , , , ,

Tapojärvi Sverige Ab recently began a new contract mining gig at the Kaunis Iron mine in Pajala, Sweden, at the same time as the temperatures in that region plummeted to around -40°C.

The service contract with Kaunis Iron covers machine work in ore production as well as production support work, which includes all open-pit production activities other than rock transportation, drilling and charging.

Miika Miettinen, Production Manager at Tapojärvi, said the contract began as agreed on January 1, with the company compiling a service package in only six weeks.

The start of a new service contract requires new personnel and equipment to carry out production in line with the contract. Additionally, production control systems, infrastructure, offices and production facilities, as well as maintenance services, are needed. A mining contractor must also consider safety at every step of production.

Approximately 60 new employees were recruited, and additional personnel were borrowed from other Tapojärvi sites, to bring this contract in within the six-week timeframe.

Miettinen highlights the professional mindset of his employer, skilled and committed personnel and new equipment as Tapojärvi’s strengths. These factors enable Tapojärvi to respond quickly to the client’s needs.

“We were forced to let the production stand idle when the temperature dropped low in early January,” Miettinen said. “There were also some struggles involving the machinery. Despite everything, our operations have been launched successfully and the client has been happy with our performance.”

To support its operations, Tapojärvi has developed processes and systems that are constantly collecting online production data. Data and analytics help enhance Tapojärvi’s performance, safety and maintenance processes.

“We are able to provide the client with comprehensive and complex production data, which allows us to influence the mine’s operations and performance together with the client,” Miettinen said. “I am glad that our cooperation with Kaunis Iron has gone smoothly from the very beginning and that we are already involved in developing the operations.”

The service contract with Kaunis Iron is Tapojärvi Sverige’s first major open-pit mine contract in Sweden. The company has previously worked in underground mines on the sites of LKAB and Zinkgruvan, for example.

LKAB bolsters automated, electric Sandvik loading fleet at Kiruna iron ore mine

Automation, Environmental, Mine operation news, Mining equipment, Mining services, Power supply for mines, Steel and iron ore, Sustainable mining, , , , , , , , , , , ,

LKAB has ordered 12 Toro™ LH625iE cable-electric loaders and five Toro™ LH621i loaders, all equipped with Sandvik’s AutoMine® solution, for its Kiruna iron ore mine in northern Sweden.

The order will more than double Kiruna’s electric Toro LH625iE fleet to 20, all of which will now be automated, and its total Sandvik loader fleet to 28 by the end of 2025, the OEM said.

The orders were booked in the June and December quarters of 2023, with deliveries scheduled from January 2024 through the end of 2025. The investment follows a study by Sandvik’s Trans4Mine team and calculations by Polymathian that identified opportunities for Kiruna to increase production by as much as 15% through automation of its large electric loader fleet.

“Sandvik and LKAB have a shared goal to boost production at the Kiruna mine,” Magnus Backe, General Manager LKAB Kiruna, said. “This is a true partnership to increase tonnage and improve safety through automation.”

Developed in 2020 as a collaboration between LKAB and Sandvik to replace Kiruna’s ageing fleet of 17 Sandvik LH625E loaders, the 25-t-payload Toro LH625iE is a revamped version of the industry’s largest-capacity underground loader.

“This investment supports our strategy towards a more electrified, autonomous and safer mine,” Joel Kangas, Mine Manager at LKAB, said. “We need to excavate an enormous volume of rock from depths of up to 1,300 m, and we will mine even deeper in the future. These depths present a prohibitive ventilation challenge for conventional equipment of the size we need to meet production demands. We worked closely on a daily basis with the Sandvik experts on site to ensure a seamless implementation.

“Ever since we put the first Toro LH625iE straight into a production environment more than three years ago, these loaders have been the backbone in our production system, exceeding our expectations, and we look forward to incorporating these new automated units into our operation.”

Kiruna was among the industry’s earliest adopters of cable-electric loading, trialling its first Sandvik unit in 1985. The oldest of Kiruna’s Sandvik LH625E loaders was 13 years old and had more than 40,000 production hours when what began as a project to modernise the loader and a side project to enhance its cable reeling system ultimately evolved into a completely upgraded loader model with the latest technology and new components.

Sandvik collaborated closely with LKAB to customise the design of Toro LH625iE to meet Kiruna’s needs. These included better energy efficiency than the original model with the same payload capacity and a larger, more ergonomic operator’s cabin with a turning seat that swivels 180°.

Mats Eriksson, President of Sandvik Mining and Rock Solutions, said: “[The] Toro LH625iE has proven itself at the Kiruna mine, delivering an unrivalled production capacity of up to 500 metric tons per hour. Not only are these automated loaders extremely productive, they improve underground conditions and operator comfort with less heat, fewer vibrations and lower noise levels. Our partnership will create value for LKAB for years to come, and we look forward to continuing to support LKAB’s goals to mine more sustainably and productively.”

The Toro LH625iE is 14 m long and features a 4-m-wide, 9 cu.m bucket and an energy-efficient, IE4 classified electric motor to deliver a low cost per tonne. It connects to Kiruna’s mine network via a 350-m trailing cable that enables an operating range of up to 700 m.
