Gold Extraction Recovery Processes - 911 Metallurgist

Gravity concentrator has two main characteristics, coarse gold particles can be recovered and the operative cost is low. 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.
