The steelmaking process starts with the processing of raw iron ore. The rocks that are mined containing iron ore are ground and the nearelemental iron is extracted using magnetic rollers. This fine iron ore is then processed into clumps that can be put inside of a blast furnace. At the same time, coal is cleaned of impurities in a furnace.

The method does not use water to process iron ore, instead it transforms mining tailings – with low iron content and no commercial value – into high iron content and low contaminants, making it economically viable. As iron ore must be composed of grades of at least 58 per cent, mining companies stack the lower grade material on tailings dumps.
