conclusion on magnetic separation of chromite

Magnetic separation. The magnetic separation method separates ore from the gangue particles based on the magnetic properties of either ore or matrix. In this method, the ore is finely crushed and passed over the magnetic roller, where one is magnetic, and the other is nonmagnetic. Example Fe (CrO 2) 2 (Chromite) is a magnetic ore . Get Price
