Magnetic separation is the process of separating components of mixtures by using a magnet to attract magnetic substances. [1] 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-,
