Our integrated route uses iron ore, coke (a purified form of coal) and some recycled steel. Iron ore is reduced and melted in the blast furnace to form liquid iron, using coke as the reductant and primary source of heat. The liquid iron is either solidified as pig iron or converted to steel, along with steel scrap, in the basic oxygen furnace ...
