blast furnace required bauxite powder

  • Smelting of Bauxite Residue (Red Mud) in View of Iron and

    In the smelting approach, bauxite residue is treated in a blast furnace with prior sintering in the presence of a reducing agent in order to reduce the iron oxides, generating pig iron and slag. Low concentrations of iron and high concentrations of sodium are the major draw-backs for utilizing bauxite residue in the blast furnace [2].
