Because of the large proportion of gold, gravity separation process is the most common method of recovering gold, and is often used in combination with other gold separation methods to treat all kinds of gold ores, especially the alluvial gold mine. Gravity separation process mainly uses the different gravity of gold and other minerals to

gold processing, preparation of the ore for use in various products. For thousands of years the word gold has connoted something of beauty or value. These images are derived from two properties of gold, its colour and its chemical stability. The colour of gold is due to the electronic structure of the gold atom, which absorbs electromagnetic radiation with wavelengths less than 5600 angstroms

Because of the activation of the gold element, gold occurs in monomeric form in gold with great density. As for this kind of placer gold mining equipment or gold miner equipment, gravity separation equipment is most efficient and economical gold mining or mining equipment.

The difference between the specific gravity of gold (19.0) and the low specific gravity of the gangue (2.7) makes gravity concentration the primary means of recovery free gold particles. In general, gravity separation has some advantages over flotation and leaching, it needs significant lower capital investment, less power and low handling costs.

Gravity methods use the difference in the density of minerals as the concentrating agent. In heavy-media separation (also called sink-and-float separation), the medium used is a suspension in water of a finely ground heavy mineral (such as magnetite or arsenopyrite) or technical product (such as ferrosilicon).
