Gravity Separation- Principle, Uses and Applications

Gravity separation, also known as gravity concentration in mineral processing, is a technique of separating valuable minerals from gangue, based on their specific weight differences. It is applied using water, particular liquids, or even air. The process of concentrating ores using gravity separation has many advantages.

Mineral Comminution and Separation Systems

An important difference of classification or gravity (or centrifugal) separation against solid-liquid or solid-gas separation, however, is that the particles should be dispersed individually in the former processes, while flocculation of particles is in favor of the latter separation processes.
