Magnetic Separation Method Mineral Processing Metallurgy

Magnetic separation has two major applications in mineral processing plants: The removal of tramp iron (which would deleteriously affect subsequent processes) from an ore stream. This is usually achieved by a low intensity magnet suspended above, or at the head of, a conveyor. Separation of magnetic minerals from less magnetic minerals.
