Magnetic Separation and Iron Ore Beneficiation – IspatGuru

04/10/2018  Magnetic Separation and Iron Ore Beneficiation Magnetic separation is an old technique for the concentration of iron ores and for the removal of tramp iron. Since 1849, a number of patents on magnetic separation have been issued in USA, and texts of some of the patents before 1910 describe a variety of magnetic separators for mineral processing.

Beneficiation - Wikipedia

Gravity separation uses centrifugal forces and specific gravity of ores and gangue to separate them. Magnetic separation is used to separate magnetic gangue from the desired ore, or conversely to remove a magnetic target ore from nonmagnetic gangue. DMS is also considered a physical separation.
