Concentration of Ores: Hydraulic Washing, Froth Flotation ...

Another method of concentration of ores is the Froth Flotation Method. This is the process for concentration of primarily sulphide ores. It has the advantage over gravity separation because it can collect even the extremely fine particles of minerals. The process uses the difference in the wetting characteristics of minerals and gangue.

Gravity separation dates back to at least 3000 BC when Egyptians used the technique for separation of gold. It is necessary to determine the suitability of a gravity concentration process before it is employed for concentration of an ore. The concentration criterion is commonly used for this purpose, designated in the following equation (where ...

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.
