Magnetic separation in mineral processing
Magnetic separation (mag sep) is a process that separates solids/solids mixtures using a magnet, which extracts the magnetic components from the non-magnetic ones. It is most often used in mining and mineral processing applications, although it is also used in recycling applications to separate plastic from metals.
