Magnetic separation process: a. The magnetic separation process is based on the differences in magnetic properties of the ore components. b. If either ore or the gangue is attracted by a magnet then the ore can be separated from the impurities with the help of magnetic separation method. c. It requires an electromagnetic separator which consists of a brass or leather belt moving over two rollers one of which is magnetic in nature as shown in the figure.

Magnetic separation : ALS

Magnetic separation exploits the different magnetic properties in ore bodies to retrieve target minerals from gangue. The process utilises the competition between gravitation centrifugal and friction forces magnetic forces and inter-particle attraction or repulsion. All magnetite ore bodies will require some magnetic separation investigation.

Magnetic Separation and Iron Ore Beneficiation – IspatGuru

Magnetic separation can be conducted either in a dry or in a wet environment although wet systems are more in use. Magnetic separation is a physical separation of discrete particles based on the three way competition between tractive (i) magnetic forces (ii) gravitational hydro-dynamic drag frictional or inertial forces and (iii) attractive or repulsive inter-particle forces.
