magnetic separator process drum magnetic separation

Magnetic separation

Magnetic separation is the process of separating components of mixtures by using a magnet to attract magnetic substances. The process that is used for magnetic separation separates non-magnetic substances from those which are magnetic. This technique is useful for the select few minerals which are ferromagnetic (iron-, nickel-, and cobalt-containing minerals) and paramagnetic. Most metals, including gold, silver and aluminum, are nonmagnetic. It is proposed that the capture of magnetic particles in the wet drum magnetic separator is by a flocculation process which proceeds rapidly at high pulp The mechanism of magnetics capture in the wet drum
