9.5.2 Utilization of subeconomic iron ores. As magnetic separators progress toward larger capacity, higher efficiency, and lower operating costs, some subeconomic iron ores have been utilized in recent years. For example, magnetite iron ore containing only about 4% Fe (beach sands or ancient beach sands) to 15% Fe (iron ore formations) and oxidized iron ore of only about 10% Fe (previously mine waste) to 20% Fe (oxidized iron ore

Oct 04, 2018 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 is used when either the ore (or) the impurities in it are magnetic in nature. Ex: Separating iron from its ore hematite Froth flotation separates the gangue particles from the ore, based on the fact that gangue is wetted by water, while mineral is wetted by oil. The ore is crushed into fine powder and mixed in water

Magnetic separation is the process of separating components of mixtures by using magnet to attract magnetic materials. The process that is used for magnetic separation detaches non-magnetic material with those that are magnetic. This technique is useful for not all, but few minerals such as ferromag

Magnetic Separation. It is based on the principle of magnetic properties of the ore components. If either the ore particles or the gangue are capable of being attracted in a magnetic field, magnetic separation can be used. Ore is kept in a conveyer which passes through the magnetic roller.
