The 2 basic points for understanding how magnetic separation works
Two basic points are necessary for understanding magnetic separation: 1. Magnetic forces are generated by non-homogeneous magnetic fields. A homogeneous magnetic field torques, but does not generate a force over a magnetic moment. A magnetic force, however, is created by varying the magnetic field over a defined area …

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.
