  • Magnetic Separation and Iron Ore Beneficiation – IspatGuru

    2018-10-04  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. Magnetic separation methods are used to

    Magnetic separation can also be used in electromagnetic cranes that separate magnetic material from scraps and unwanted substances. This explains its use for shipment equipments and waste management. Unwanted metals can be removed from goods with this technique. It keeps all materials pure. Recycling centres use magnetic separation often to separate components from recycling, isolate metals, and purify ores. Overhead magnets, magnetic pulleys, and the magnetic drums were the methods used in the rec
