    Iron ore slime which is a waste material contains 56% of iron. Two different chemical treatment methods and electrowinning method were separately studied to upgrade iron content up to 60% or above. Acid extraction and alkali extraction can upgrade iron content maximum 63% (w/w) and 65 % (w/w) respectively. Electrowinning directly produces high purity iron without involvement of blast furnace ...

  • Magnetic Separation and Iron Ore Beneficiation – IspatGuru

    Magnetic Separation and Iron Ore Beneficiation Magnetic separation is an old technique for the concentration of iron ores and for the removal of tramp iron. Since 1849, a number of patents on magnetic separation have been issued in USA, and texts of some of the patents before 1910 describe a variety of magnetic separators for mineral processing.
