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.
