Sierra Leone woos miners to clean energy with $11 billion plan
Most mining firms rely on their own diesel supplies to extract iron ore, diamonds, rutile and bauxite in the resource-rich country.
The world’s largest iron ore miner Rio Tinto said on Friday it signed a memorandum of understanding (MOU) with China’s Nanjing Iron and Steel Co (NISCO) on decarbonization technology in ironmaking.
Technical teams from both companies will work closely on exploring pelletizing using the Pilbara fines and the application of biomass.
Rio’s flagship product Pilbara blended fines are typically used to make sintered ore, used in blast furnaces to produce hot metal.
And pelletization usually requires higher grade iron ore, which is helpful for reducing carbon emissions along the steel value chain.
“We are pleased to have reached a new milestone in steel carbon reduction … the low carbon transition in the steel industry needs high-quality raw material and massive technological innovation,” said Simon Farry, head of steel decarbonization at Rio.
Upstream mining giants have accelerated cooperation with their big consumers on decarbonizing the steel value chain to cope with climate change.
Rio Tinto last year signed a MoU with China Baowu, the world’s biggest steelmaker by volume, to develop projects aimed at enabling lower grade ore to be used in low-carbon steelmaking.
It’s rival BHP Group and Chinese steel company HBIS Group Co Ltd, agreed last March to trial carbon capture, utilization and storage (CCUS) technologies at the Chinese firm’s steel mills.
