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.
The Dense medium separation (DMS) or heavy medium separation (HMS), or Sink-Float gravimetric separation, also known within the field of the scrap treatment as Flotation, is a process used to separate materials that have different specific weight.
