Magnetic Separation and Iron Ore Beneficiation –

2018-10-4  Magnetic separator separates the iron ore feed material into two or more components. If the purpose is to produce a magnetic concentrated iron ore then the other component which is non-magnetic is the tailings. In some cases there can also be a possibility of separating the less magnetic third component which is called middlings.

concentration of ore by magnetic separation method

Magnetic separation: This method of concentration can be applied when the gangue and the ore particles have different magnetic properties. For example, if the ore particles are magnetic in nature and if the gangue particles are nonmagnetic, then a strong magnet can be brought and the magnetic ore particles can be sucked out from the powdered ...
