steps in the modern steelmakingprocess

Aug 21, 2020·Two processes, basic oxygen steelmaking (BOS) and electric arc furnaces (EAF), account for virtually all steel production. Ironmaking, the first step in making steel, involves the raw inputs ofiron ore, coke, and lime being melted in a blast furnace

genesis, uses and environment implications of iron oxides

Ironoxides are chemical complexes which occur naturally, comprisingironand oxygen. Here, together, 16 types ofironoxides and oxyhydroxides have been identified. Thesetwocomponents of oxides are widely spread naturally. They are vital to humans and useful in most geological and biological activities. In addition, they are useful as pigments and catalyst in industries and hemoglobin in
