Magnetic Separation - Mining Fundamentals

Magnetic separation is the process by which magnetically susceptible material is separated from a mixture by the application of a strong magnetic field. Iron ores are usually subjected to the magnetic separation process, due to the high magnetic susceptibility of iron.

Magnetic Separation - Washington University in St. Louis

Minerals fall into one of three magnetic properties: ferromagnetic, paramagnetic and diamagnetic. Ferromagnetic minerals are themselves magnetic (i.e., magnetite and pyrrhotite) and can be easily separated from other minerals with a magnet since they will stick to the poles of the magnet. These minerals can be separated by wrapping the poles of a magnet in paper, passing the magnet over the mineral mixture. The ferromagnetic minerals

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 that are magnetic. This technique is useful for not all, but few minerals such as ferromagnetism/ferromagnetic (materials strongly affected by magnetic fields) and paramagnetic(materials that are less affected) but the effect is still noticeable). Not all metals are magnetic; gold, silver and alu
