PERTH, Australia--(BUSINESS WIRE)-- Australia's two largest iron ore producers and its biggest steelmaker have partnered in their efforts to accelerate the decarbonisation of steelmaking by agreeing to jointly investigate the development of the country's first ironmaking Electric Smelting Furnace 1 (ESF) pilot plant.. Under a new framework agreement, Rio Tinto, BHP and …
Iron ore, extracted through ore mining, stands as the primary source of iron and serves as a fundamental building block for steel production. The process involves the integration of coal, a crucial energy source, contributing to the creation of coke in the electric arc furnaces, which aids in reducing iron ore to molten metal.
The steel making process involves several key stages: preparation of raw materials such as iron ore, coke, and limestone; smelting and reduction to produce molten iron; primary steelmaking which converts molten iron to steel …
