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: 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.
