Electromagnetic separation; As the name suggests, magnetised material, such as a magnet-equipped roller, is used for separating the unwanted particles to enrich the ore. The magnetic characteristics of the ore or the gangue particles are used for separation. The ore is powdered and is laid on a conveyor belt that passes through a magnetic roller.

A successful separation of a valuable mineral from its ore can be determined by heavy-liquid testing, in which a single-sized fraction of a ground ore is suspended in a liquid of high specific gravity. Particles of less density than the liquid remain afloat, while denser particles sink. Several different fractions of particles with the same ...
