Gold Extraction & Recovery Processes

 · 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.

Processes

The specific gravity of gold is 19.3, so it is 19.3 times as dense as water. When separating free gold from a typical quartz deposit, gravity concentration must separate based on specific gravities of 19.3 and 2.6, for gold and quartz respectively.
