Gravity separation and Ore Beneficiation – IspatGuru

Gravity separation is a physical process which consists of the separation of different mineral types in the ore from one another based on differences in their specific gravities using the force of gravity, which can be influenced by one or more of other forces such as centrifugal force, resistance to motion by a fluid (e.g. air, water) etc ...

Jigging

Jigs are continuous pulsating gravity concentration devices. Jigging for concentrating minerals is based exclusively on the differences in density of the particles. The elementary jig (Fig. 13.29) is an open tank filled with water.A thick bed of coarse heavy particles (ragging) is placed on a perforated horizontal jig screen.
