Gravity separation - Wikipedia

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.

Solids Processing Dry Separation Methods

Specific gravity separation While most engineers in industries that process dry materials know what a gravity separator (Figure 2) does, its work is difficult to define with precision. The statement “a separator classifies dry, free-flow-ing, granular mixtures by weight or bulk density or specific gravity” is accurate.
