The primary raw materials that the steel industry utilizes are mainly two types of iron oxides: magnetite (Fe 2 O 3, 72.4% Fe) and hematite (Fe 3 O 4, 69.9% Fe). The high iron content in these compounds allows their direct feed into a blast furnace to produce pig iron and further treatment (Cornell and Schwertmann, 2003). Production of iron ...
