Gravity concentration is the separation of minerals based on differences in specific gravity. A gravity concentration process is designed to recover very high grades of valuable ore material into very small masses. The resurgence of gravity concentration in mining has come about due to its simplicity and low environmental impact.

Gravity separation is an industrial method of separating two components, either a suspension, or dry granular mixture where separating the components with gravity is sufficiently practical: i.e. the components of the mixture have different specific weight. All of the gravitational methods are common in the sense that they all use gravity as the dominant force.
Advances in Centrifugal Gravity Concentration
For example, acanthite and proustite, with specific gravities of 7.2 and 5.6 respectively, should be recoverable by gravity concentration methods. Since these minerals are present at higher concentrations (than typical gold ores) and that they may be locked with other sulfides, fluidized bed batch-type machines cannot produce the mass yields ...

A new method for gravity separation: Vibrating table ...
· 1. Introduction. In its simplest definition, gravity concentration is a class of methods which take advantage of the density differences among mineral particles,, .As a result, particles of which densities are different from each other have their own relative movement against the forces of the gravity depending on the factors such as viscosity of the environment, resistance to the motion in ...
Gravity concentration. 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 forces, magnetic forces, buoyant forces), one of which is resistance to motion (drag force) by a viscous medium such as ...
