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 powdered ore is 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. The magnetic part of the ore clings to the belt for a longer distance and forms another heap near the magnet.

For example, nonmagnetic SnO is separated from magnetic FeWO

present in the ore Cassiterite by magnetic separation process.
