magnetic separation process of ores

Magnetic separation process of ores: An electromagnetic separator is required.A leather or brass belt moves over two rollers, one of which encloses magnets in it. The powderedoreis dropped over this moving belt at one end.The non magnetic part of the ore is not attracted by the magnet and falls to form a separate heap at a distance.
