3. Types of separation or concentration of an ore - YaClass
The concentration of the crushed ore is done mainly by the following methods: 1. Hydraulic (Gravity Separation) method: Principle: The difference in the density or specific gravity of the ore and gangue is the main principle behind this method. Oxide ores are purified by this method.

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.
