How the impurities are separated from ore with the help of magnetic separation

Electro-magnetic method : The method is used if the gangue or the ore particles are magnetic in nature. The Finely prwdered ore is dropped on a belt moving on two strong electromagnetic rollers. The magnetic and the non-magnetic substances form two separate heaps. for example ,let the ore particles be magnetic and then the non-magnetic roller

    Magnetic separation process of ores: An electromagnetic separator is required. A leather or brass belt moves over two rollers, one of which encloses magnets in it. The powdered ore is dropped over this moving belt at one end. The non magnetic part of the ore is not attracted by the magnet and falls to form a separate heap at a distance

    This is generally used when the metal ore is much heavier than the impurities. Magnetic Separation: The name of the concentration process is enough to explain. This technique is used to separate the ferromagnetic metal ore from the impurities after pulverizing. The ground ore particles are carried on a conveyor belt with two wheels

    Apr 02, 2020 If either ore or the gangue (one of these two) is attracted by a magnet then ore can be separated from the impurities with the help of magnetic separation method. For example: 1) The magnetic impurities such as iron and manganese tungstates (FeWO 4,MnWO 4) present in tin stone (SnO 2, non-magnetic) are separated by this method

    Magnetic Separation - an overview | ScienceDirect Topics

    Magnetic separation takes advantage of the fact that magnetite is strongly magnetic (ferromagnetic), hematite is weakly magnetic (paramagnetic), and most gangue minerals are not magnetic (diamagnetic). A simple magnetic separation circuit can be seen in Figure 1.2.5 [9].A slurry passes by a magnetized drum; the magnetic material sticks to the drum, while the nonmagnetic slurry keeps flowing

    Wolframite ore (F e W O 4 ) is present in tin stone in the form of impurities and same mass per unit as tin stone.Wolframite is magnetic in nature and tin stone is non-magnetic in nature. They are separated by magnetic separation, Wolframite is attracted by magnet and falls just below magnet while tin stone falls away from it

    Magnetic separation: This method of metallurgy is used when either the ore or the impurities are magnetic in nature. For example, magnetic ores like pyrolusite (MnO 2) and chromite (FeO.Cr 2 O 3) having a difference in the magnetic properties of the ore and gangue particles. In this method, the ground ore is carried on a conveyor belt rotating
