Concentration of Ore Learn Important Terms and Concepts

The concentration method of iron ore is magnetic separation. The powdered magnetite or hematite is subjected to a conveyer belt and when the magnetic roller starts rotating, the iron particles get attracted towards the roller and all other impurities are separated away from it. In the ore iron, the mineral pyrite is found associated with it.

Concentration of ore - simply.science

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 non – magnetic, then a strong magnet can be brought and the magnetic ore particles can be sucked out from the powdered ore.
