Magnetic separation - Wikipedia

Magnetic separation is the process of separating components of mixtures by using a magnet to attract magnetic materials. The process that is used for magnetic separation separates non-magnetic materials from those that are magnetic. This technique is useful for the select few minerals which are ferromagnetic (iron-, nickel-, and cobalt-containing minerals) and …
