Gravity concentration processes rely on the principal that gold contained within an ore body is higher in specific gravity than the host rocks that contain the gold. Elemental gold has a specific gravity of 19.3, and typical ore has a specific gravity of about 2.6. All gravity concentration devices create movement between the gold and host rock particles in

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 gold concentration separator, or centrifugal concentrator, is a new type of gravity concentration equipment for concentrating gold and other high density minerals. It is used for roughing separation to recover most of the useful minerals. It can be used not only for placer gold mining, but also for hard rock mining to recover the natural gold.
