Various Types Of Iron Ore Beneficiation Processes
Another common method of beneficiation is through magnetic separation, which exploits the difference in magnetic properties between iron minerals and gangue minerals. By subjecting the crushed ore to a magnetic field, the iron-rich particles can be separated from other non-magnetic particles, resulting in a concentrate rich in iron content.
