    Magnetic separation - Wikipedia

    Magnetic Separation is the process of separating components of mixtures by using magnets to attract magnetic materials. The process that is used for magnetic separation detaches non-magnetic material with those who are magnetic. This technique is useful for not all, but few minerals such as ferromagnetic (materials strongly affected by magnetic fields) and paramagnetic (materials that are
