    BHP Inks MoU with HBIS to Cut Emissions in Steel Industry

    BHP has signed a MoU with one of the world’s largest steelmakers and a major customer of BHP’s iron ore China’s HBIS Group Co Ltd with the intention of investing up to USD 15 million over three years to jointly study and explore greenhouse gas emissions reduction technologies and pathways. Under the partnership, BHP and HBIS Group intend to collaborate on three priority areas: hydrogen-based direct reduction technology, the recycling and reuse of steelmaking slag, and the role of iron ore lump utilisation to help reduce emissions from iron making and steelmaking. The partnership aims to help both companies progress toward their climate change goals, and support the steel industry’s role in helping to achieve China’s ambitions to be carbon neutral by 2060.

    BHP’s Chief Commercial Officer Ms Vandita Pant said “We view decarbonisation of the steel industry as a complex puzzle that requires multiple technological solutions across the value chain over different time horizons. By forming this third low-carbon steelmaking partnership with HBIS Group, we are focusing on additional components, such as the role our products play in hydrogen-based steel production, that complement our other partnerships and support for endeavours in emissions reduction and capture from the traditional blast furnace route.”

    BHP’s investment would be drawn from its USD 400 million Climate Investment Program established in 2019 to support projects, partnerships, research and development to help reduce Scope 1, 2 and 3 emissions.

    The MoU with HBIS Group follows recent partnerships established with major steelmakers China Baowu and JFE to explore emissions reduction from steelmaking. BHP has been active in other areas to reduce emissions, including awarding the world’s first LNG-fuelled Newcastlemax bulk carrier tender and the first LNG supply agreement for those vessels, and renewable energy supply contracts for BHP’s Queensland coal mines and Nickel West operations.

    Rio Tinto to Build New Tellurium Plant at Kennecott Mine in Utah

    Rio Tinto will begin construction on a new plant that will recover tellurium, a critical mineral used in solar panels, from copper refining at its Kennecott mine near Salt Lake City in Utah in US. Rio Tinto is investing USD 2.9 million to set up the plant, which will recover tellurium as a byproduct of copper smelting, extracting a valuable mineral from waste streams. The plant will have a capacity to produce approximately 20 tonnes of tellurium per year. Rio Tinto expects to begin production of tellurium in the fourth quarter of 2021, creating a new North American supply chain for this critical mineral.

    Tellurium is an essential component of cadmium telluride, a semiconductor used to manufacture thin film photovoltaic solar panels. Thin films made of this compound can efficiently convert sunlight into electricity. Tellurium can also be used as an additive to steel and copper to improve machinability, making these metals easier to cut. It can also be added to lead to increase resistance to sulfuric acid, vibration and fatigue.

    Tellurium is a chemical element with the symbol Te and atomic number 52. It is a brittle, mildly toxic, rare, silver-white metalloid. Tellurium is chemically related to selenium and sulfur, all three of which are chalcogens. It is occasionally found in native form as elemental crystals. Tellurium is far more common in the Universe as a whole than on Earth. Its extreme rarity in the Earth's crust, comparable to that of platinum, is due partly to its formation of a volatile hydride that caused tellurium to be lost to space as a gas during the hot nebular formation of Earth and partly to tellurium's low affinity for oxygen, which causes it to bind preferentially to other chalcophiles in dense minerals that sink into the core.

    Along with producing almost 20 per cent of US copper, Kennecott’s smelting process also recovers gold, silver, lead carbonate, platinum, palladium and selenium, while molybdenum is recovered from the Copper concentrator. In total, nine products are currently recovered from the ore extracted at Kennecott.

    Rio Tinto Update on WTSP 2 Expansion at Tom Price Iron Ore Mine

    Rio Tinto has to date awarded contracts valued at over AUD 500 million to local Western Australian and Pilbara Aboriginal businesses to support the latest development of its Greater Tom Price Operations. Construction of the Western Turner Syncline Phase 2 expansion commenced in early 2020 and to date more than 85% of spending on the project has been awarded to Western Australian and Pilbara Aboriginal businesses, directly through Rio Tinto or principal contractor Mondium. At peak construction, development will support a workforce of over 1,000 people with the majority employed by WA businesses, including Guma Warnii, Monadelphous, Mondium, Kerman Contracting, Whittens, North West Mining & Civil, MACA Civil, Linkforce and Aerison.

    Rio Tinto approved the AUD 1 billion investment in the mine in November 2019 to sustain production capacity of its iron ore business in the Pilbara. The investment allows for the mining of existing and new deposits at WTS2 and includes construction of a new crusher and a 13-kilometre conveyor which will help lower greenhouse gas emissions from the mine by 3.5% compared to road haulage. First production from the new deposits at WTS2 is expected in the second half of 2021.

    Western Turner Syncline Phase 2 is located in the Pilbara region of Western Australia 35 kilometres north-west of the Tom Price mine from where its ore is ultimately processed and loaded onto rail. Rio Tinto’s Greater Tom Price production hub includes the Tom Price, Western Turner Syncline Phase 1 and Western Turner Syncline Phase 2 satellite hubs. Rio Tinto commenced development of Western Turner Syncline Phase 2 in 2014 and expansion plans commenced in 2019. The investment in the WTS2 mine will help sustain the current workforce at Rio Tinto’s Greater Tom Price production hub. The project is expected to deliver an attractive internal rate of return with a capital intensity of about AUD 25 per tonne of production capacity.

    Fortescue Strengthens Target for Carbon Neutrality by 2030

    Fortescue Metals Group Ltd Chairman Dr Andrew Forrest announced Fortescue’s target to achieve carbon neutrality by 2030, ten years earlier than the previous target. Fortescue Future Industries, a wholly owned subsidiary of Fortescue, will be a key enabler of this target through the development of green electricity, green hydrogen and green ammonia projects in Australia. Dr Forrest said “We have joined the global battle to defeat climate change. We are trialling and demonstrating green hydrogen technologies in global-scale commercial environments, while also rapidly evolving into a green hydrogen and electricity producer of similar scale. Our commitment to demonstrate green hydrogen’s economic value in world-scale operations, and become a major energy exporter, while implementing the considerable facilities to support both, means that Fortescue has emerged not simply as a thought-leader and investor, but uniquely as an executor of major green hydrogen projects. Our aim is to provide the two missing links in the climate change battle, to create both the demand and the supply of green hydrogen. Due to its high energy performance and environmental neutrality, green hydrogen and direct green electricity has the potential to eliminate fossil fuels from supply chains. Once established, these advances will also substantially reduce Fortescue’s operating costs. Fortescue’s strong focus on green energy and our carbon neutrality targets will sit alongside our continuing excellence in, and commitment to, our iron ore business. While our green energy and industry initiatives may one day significantly outscale our iron ore business due to the global demand for renewable energy, our commitment to iron ore and resources globally remains indefeasible.”

    Fortescue is seeking to move from being a major consumer of fossil fuel with a current trajectory of more than 1 billion litres a year of diesel being used across the operations if no remedial action is taken - to a major clean and renewable energy exporter. FFI is advancing projects across Australia including Tasmania, to build large-scale renewable energy and green hydrogen production capacity. This will expedite the substitution of green hydrogen and green ammonia for carbon-based fuels. These projects will, with the support of Australia’s governments, contribute to a significant reduction in national carbon emissions. Through FFI and its highly committed Operations team, Fortescue is undertaking to deliver several key projects by the stretch target of 30 June 2021. This will underpin its pathway to decarbonisation. These projects include

    Developing a ship design powered by green ammonia and trialling that design in new ammonia engine technology, at scale

    Testing large battery technology in our haul trucks

    Trialling hydrogen fuel cell power for our drill rigs

    Trialling technology on our locomotives to run on green ammonia

    Conducting trials to use renewable energy in the Pilbara to convert iron ore to green iron at low temperatures, without coal.

    In June 2020, Fortescue announced an industry-leading target to achieve net zero operational emissions by 2040. This included a 26 percent reduction in Scope 1 and 2 emissions from existing operations by 2030 relative to 2020 levels.

    Rio Tinto Outlines Path to Stronger Cultural Heritage Management

    Rio Tinto detailed last week detail how it is working in partnership with Traditional Owners, host communities and independent groups to strengthen and improve its approach to cultural heritage and community relations. In virtual seminars, which will include presentations from Board and Executive Committee members as well as experts in the field, Rio Tinto will outline actions it has introduced to strengthen its performance and governance of cultural heritage following the destruction of the rockshelters at Juukan Gorge in May 2020 and outline the steps it will take to further improve its performance. One key step is confirmation that an Indigenous Advisory Group will be established to ensure Rio Tinto has a better understanding of Indigenous culture and issues in Australia, including at Board level. It follows broad consultation with Traditional Owners and Indigenous leaders with the aim to introduce more diversity and breadth of views, including external perspective, in decision-making.

    Rio Tinto has also commenced work to review and re-define what best practice for cultural heritage management is in the mining industry. This work will be done in consultation with the IAG and other independent parties and will enable Rio Tinto to identify gaps in current protocols and provide a clear pathway to re-establish trust over time and regain Rio Tinto’s previous standing in this area.

    Following the events at Juukan Gorge, Rio Tinto reviewed its internal processes and also consulted widely with Traditional Owners, host communities, governments and other stakeholders. As a result, the company has significantly strengthened internal practices, policies and governance.

    As part of Rio Tinto’s efforts to increase transparency in its approach to cultural heritage, the company has also committed to additional disclosures on the progress of heritage measures being undertaken. Rio Tinto is also engaging with a number of global investors and investor groups1, to jointly identify additional disclosures on:

    Progress against Rio Tinto’s own commitments and internal work-streams, (including Trusted Partnership Plan), external obligations and recommendations

    How Traditional Owners’ views are being sought and considered in shaping these commitments and Traditional Owners’ perspectives on how successfully these commitments are being met

    Enhanced governance arrangements in place to oversee the company’s progress against these actions

    How the company is working to advocate for enhanced sector-wide cultural heritage management and how this is consistent with Rio Tinto’s internal standards

    Rio Tinto intends to commence with interim reporting in the third quarter of 2021 and thereafter with predominantly annual reporting, coupled with periodic disclosure as appropriate. Further consultation with a broad range of investors and other stakeholders will continue to assist in developing these disclosures over time.

    Rio Tinto Selects Heliogen’s Solar Technology for Boron Mine

    Rio Tinto and Mr Bill Gates backed renewable energy technology company Heliogen announced an agreement to explore the deployment of Heliogen’s breakthrough solar technology at Rio Tinto’s borates mine in Boron in California. Under a Memorandum of Understanding, Heliogen will deploy its proprietary, artificial intelligence powered technology at the Boron operation, where it will use heat from the sun to generate and store carbon-free energy to power the mine’s industrial processes. The two companies will begin detailed planning and securing government permits for the project, with the aim of starting operations from 2022. The companies will also use the Boron installation to begin exploring the potential for deployments of Heliogen’s technology at Rio Tinto’s other operations around the world to supply process heat, which accounted for 14 per cent of Scope 1 & 2 emissions from the Group’s managed operations in 2020.

    Heliogen’s high-temperature solar technology is designed to cost-effectively replace fossil fuels with sunlight for a range of industrial processes, including those used in mining. At Rio Tinto’s Boron mine, the company’s proprietary technology will use AI to control a network of mirrors that concentrate sunlight to capture energy used to make steam. Heliogen’s system will also store the captured energy in the form of heat, allowing it to power nighttime operations and providing the same uninterrupted energy stream offered by legacy fuels.

    The Boron operation mines and refines borates into products ranging from fertilizers to construction materials and is producing lithium carbonate from a demonstration plant. The site currently generates steam using a natural gas cogeneration plant and natural gas fired boilers. Heliogen’s installation will supplement these energy sources by generating up to 35,000 pounds per hour of steam to power operations, with the potential to reduce carbon emissions at the Boron site by around 7 per cent – equivalent to taking more than 5,000 cars off the road. Rio Tinto will also be assessing the potential for larger scale use of the Heliogen technology at Boron to reduce the site’s carbon footprint by up to 24 per cent.

    Heliogen’s mission of slashing global carbon emissions by replacing fossil fuels with sunlight, as well as its focus on industrial sectors, made them an ideal partner for Rio Tinto, which is committed to decarbonizing its global operations.

    Rio Tinto Achieves Battery Grade Lithium Production at Boron plant

    Rio Tinto has commenced production of battery-grade lithium from waste rock at a lithium demonstration plant at the Boron mine site in California, United States. The demonstration plant is the next step in scaling up a breakthrough lithium production process developed at Boron, to recover the critical mineral and extract additional value out of waste piles from over 90 years of mining at the operation. An initial small-scale trial in 2019 successfully proved the process of roasting and leaching waste rock to recover high grades of lithium.

    The demonstration plant has a design capacity of 10 tonnes per year of battery grade lithium. It will be run throughout 2021 to optimise the process and inform Rio Tinto’s feasibility assessment for progressing to a production scale plant with an initial capacity of at least 5,000 tonnes per year, or enough to make batteries for approximately 70,000 electric vehicles.

    Rio Tinto’s lithium pipeline includes the Jadar lithium-borate project in Serbia, for which a feasibility study is expected to complete by the end of 2021.

    Development of the lithium project at Boron draws on Rio Tinto’s long standing partnership with the U.S. Department of Energy’s Critical Materials Institute, which is focussed on discovering ways to economically recover critical mineral by-products from existing refining and smelting processes. CMI experts worked alongside Rio Tinto technical leads to help solve a number of key processing challenges to produce battery grade lithium at Boron.

    NPROXX Hydrogen Tank for Truck in Anglo American Mine

    NPROXX is currently completing the manufacture of an innovative new hydrogen fuel tank system that is designed to power the world’s largest mine haul truck at an Anglo American PGM mine in South Africa. Once it has been delivered, installed onto the vehicle and qualified, the hydrogen tank system will drive a fuel cell that provides a zero-emission solution for materials hauling that is not currently available in the market. The hydrogen-powered truck will be trialed at Anglo American’s Mogalakwena mine, the largest open pit platinum group metals mine in the world, after which the trucks are expected to be deployed at other Anglo American operations across the world. Delivery of the power plant module to South Africa has been slightly delayed because of the COVID-19 pandemic, but NPROXX expects the vehicle to be operational in the second half of 2021.

    With its expertise in mining, Anglo American is highly experienced and has undertaken to develop the zero emission mining vehicles itself by integrating the various necessary parts with the help of partners – it turned to NPROXX to develop a tank system that could safely and cost-effectively store enough hydrogen at high pressure to power the fuel cells.

    As well as meeting the challenge of producing the pressure vessels and siting the tanks within the vehicle’s frame, NPROXX also designed and delivered a unique pipework and refueling system that could support multiple tanks on the vessel at pressures of up to 350 bar. The main challenge has been ensuring the development of a safe and robust system for the mining application, this is from the hydrogen generation all the way through to using hydrogen safely on the vehicle.

    As well as the hydrogen tank system, which is entirely designed and built by NPROXX, the pressure vessels used to store the hydrogen in the refueling station have also been provided by NPROXX.

    Anglo American has set out ambitious carbon related targets, including publicly committing to carbon neutrality across its global operations by 2040. Given that large trucks currently account for over 70% of diesel consumption on-site, switching from diesel to hydrogen will help move the company closer to its goal of operating carbon neutral mines. Anglo American plans to generate hydrogen from electrolysis on site, using renewable power sources, to power the truck. Anglo American and Engie are currently building a demonstration facility in South Africa, including a 3.5MW electrolyser to produce hydrogen on site. It has a capacity to produce up to 1 tonne per day. Producing hydrogen to fuel the truck on site will eliminate the reliance on importing fuels and generate further cost savings.
