Rio Tinto looks for commercial uses of Aymium renewable biocarbon products

Rio Tinto and Aymium have partnered to develop and trial a renewable biocarbon product for use as an alternative resource to reduce emissions in large scale industrial processes.

The product has been successfully trialled as a replacement for anthracite used in ilmenite smelting processes at Rio Tinto’s metallurgical complex in Sorel-Tracy, Quebec, a leading producer of high-grade titanium dioxide feedstock as well as iron and steel for specialised applications.

In a strengthening of the partnership, Rio Tinto has made a further equity investment in Aymium following its participation in a funding round in 2022. The second investment is part of Rio Tinto’s support for innovations needed to meet its 2030 emission reduction targets and deliver lower carbon supply chains.

The partners will now be working together on options for large-scale production of a biocarbon product.

Rio Tinto Minerals Chief Executive, Sinead Kaufman, said: “We are delighted to work with Aymium to develop and trial this renewable biocarbon product that has real potential as an alternative, low carbon resource for our processes. We are investing to deepen our partnership, as part our commitment to finding better ways to decarbonise our operations and the supply chains we are part of.”

Aymium CEO, James Mennell, said: “Our mission is to accelerate the transition away from fossil fuels and minimise our environmental impact. We are delighted about Rio Tinto’s follow-on investment as it will further advance our global mission to create bioproducts with enhanced performance and achieve ambitious emissions reduction targets.”

Funds from this investment will be directed towards advancing the construction of Aymium’s new production facilities in North America and supporting its research and development initiatives.

Aymium produces high-value biocarbon and biohydrogen products that, Rio Tinto says, can be used to immediately replace fossil fuels in the production of metals, energy, crops, and in the purification of water and air with no modifications to equipment or processes. Produced using biomass – recovered and unusable wood – Aymium’s bioproducts are renewable, carbon-negative and replace emission-heavy fossil fuels such as coal and coke, according to the company. Aymium’s technology is backed by more than 350 issued or pending patents on a global basis.

Rio Tinto to decarbonise titanium dioxide, steel and metal powders business in Quebec

Rio Tinto is partnering with the Government of Canada to invest up to C$737 million ($537 million) over the next eight years to decarbonise its Rio Tinto Fer et Titane (RTFT) operations in Sorel-Tracy, Québec, Canada, and to position the business as a centre of excellence for critical minerals processing.

The partnership will support technological innovations that represent a first step towards reducing greenhouse gas emissions from RTFT’s titanium dioxide, steel and metal powders business by up to 70%. It will also progress initiatives to diversify RTFT’s product portfolio, reinforcing Rio Tinto’s leadership as a North American supplier of critical minerals for key growth sectors such as electric vehicles, 3D printing and aerospace, the miner said.

The Government of Canada is investing up to C$222 million over the next eight years to support these initiatives through its Strategic Innovation Fund (SIF), which supports large-scale, transformative, and collaborative projects that will help position Canada to prosper in the global knowledge-based economy.

Rio Tinto Chief Executive, Jakob Stausholm, said: “Rio Tinto is committed to being part of a net-zero future, from decarbonising our operations to finding new ways to produce the materials needed for the transition. We are excited to collaborate with the Government of Canada to position RTFT for the future and strengthen the critical minerals and metals value chains in Canada and the United States.”

The Right Honourable Justin Trudeau, Prime Minister of Canada, said: “Good middle-class jobs, clean air, and made-in-Canada tech: this is our vision for a strong economy and a strong future. Today’s announcement is about delivering on that vision and positioning Canada as a leader in critical minerals – a key part of things like electric vehicles. Together, we will continue to innovate, create good jobs, and keep our air clean.”

The Honourable François-Philippe Champagne, Canada’s Minister of Innovation, Science and Industry, said: “Supporting the growth of Canada’s critical minerals supply chain will ensure that our country remains a global leader in this strategic sector. Our government is committed to the sustainable development of critical minerals resources, creating good jobs, and building strong global supply chains while strengthening trade relationships with Canada’s closest allies.”

The partnership will support projects including:

BlueSmelting

The BlueSmelting project is an ilmenite smelting technology that could generate 95% less greenhouse gas emissions than RTFT’s current reduction process, enabling the production of high-grade titanium dioxide feedstock, steel and metal powders with a drastically reduced carbon footprint.

A demonstration plant is currently under construction at the RTFT metallurgical complex in Sorel-Tracy to test and validate this technology developed by scientists from Rio Tinto’s Critical Minerals and Technology Centre. Construction of the demonstration plant, which will have a capacity to process up to 40,000 t/y of ilmenite ore, is expected to be completed in the first half of 2023.

If fully implemented, the BlueSmelting project has the potential to deliver a reduction of up to 70% in RTFT’s overall greenhouse gas emissions, a decrease of approximately 670,000 t CO2e-based on 2021 emissions or the equivalent to removing 145,000 cars from the road.

Increasing scandium production

After becoming the first North American producer of scandium, a critical mineral used in solid oxide fuel cells and aluminium alloys, earlier this year, Rio Tinto is planning to quadruple its production capacity to reach up to 12 t/y of scandium oxide, from the current nameplate capacity of three tonnes.

New modules will be added to the existing plant, which uses an innovative process to extract high purity scandium oxide from the waste streams of titanium dioxide production, without the need for any additional mining. The C$30-35 million project is expected to start producing scandium oxide in 2024.

Adding titanium metal to the portfolio

Rio Tinto is partnering with other titanium industry participants to advance the development of a new process for extracting and refining titanium metal, a high-performance material used in the medical, aerospace, and automotive industries.

Rio Tinto is setting up a pilot plant at the RTFT metallurgical complex to validate this low-cost process which requires no harmful chemicals and does not generate direct greenhouse gas emissions. The plant is expected to be completed by the end of 2023.

This project has the potential to greatly increase the production of raw titanium metal in North America, while strengthening the security of supply for this critical mineral for Canadian and US manufacturers.

Rio Tinto Kennecott to recover tellurium from copper smelting

Rio Tinto is to construct 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, Utah.

The company is investing $2.9 million to set up the plant, which will recover tellurium as a by-product of copper smelting, extracting a valuable mineral from waste streams. The plant will have a capacity to produce around 20 t/y of tellurium, the miner said.

Rio expects to begin production of tellurium in the December quarter of 2021, creating a new North American supply chain for the 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, according to the miner. 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 sulphuric acid, vibration and fatigue.

Rio Tinto Kennecott Managing Director, Gaby Poirier, said: “The minerals and metals we produce are essential to accelerate the transition to renewable energy. Adding tellurium to our product portfolio provides customers in North America with a secure and reliable source of tellurium produced at the highest environmental and labour standards with renewable energy. Rio Tinto is committed to using innovation to reduce waste in our production process and extract as much value as possible from the material that we mine and process.”

Utah Governor, Spencer Cox, said: “With abundant natural resources, Utah is ideally positioned to help supply the critical minerals essential to maintain American manufacturing competitiveness. Rio Tinto’s smelter at Kennecott is one of only two that is capable of producing copper and other critical minerals. The new tellurium plant is another valuable contribution to critical mineral independence and energy security in the US”

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

Rio Tinto is a partner with the US Department of Energy’s Critical Materials Institute (CMI) and works closely with CMI experts to discover further ways to economically recover critical mineral by-products such as rhenium, tellurium and lithium. The company is also investing in new facilities to extract battery-grade lithium from waste rock at its Boron, California mine site and high quality scandium oxide from waste streams at its metallurgical complex in Sorel-Tracy, Quebec.
