The Process of Turning Iron Ore into Steel

The steelmaking process starts with the processing of raw iron ore The rocks that are mined containing iron ore are ground and the near-elemental 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
