2021-6-19  From the rod mill the material proceeds to the cobber magnetic separators. Any non-magnetic material which has been released by the rod mill is separated and sent to the tailings thickener. Magnetite iron ore particles are separated by the magnetite separator from the gangue (waste material) minerals in the cobber magnetic separators.
