Gravity and heavy medium separation methods are used when separating minerals with different specific gravities. Typical examples of such industrial minerals include chromite and kimberlite. The method is also used in precious metal and sulphide ore combination processes and in a variety of recycling processes as an auxiliary method.

Gravity separation is the separation of two or more minerals of different specific gravity by their relative movement in response to the force of gravity and one or more other forces (such as centrifugal, drag or buoyant forces). The resistance to motion, known as drag force, by a medium such as heavy media, water or even air, is one such force.
