Hematite | Common Minerals
With all of hematite's many varieties, it is natural that some of them can be easily confused with other metallic minerals. All of the hematite varieties though, exhibit the same distinctive red to red-brown streak when scratched across a rough hard surface, which should serve to distinguish hematite from similar-appearing minerals. Magnetite:
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.
