Gravity Concentration in Artisanal Gold Mining

These methods often do not provide high gold recoveries, particularly with respect to fine gold particles. For centuries, gravity methods were gold miners'' preferred separation method as there is a large difference between the specific gravity (sg) of gold (sg ≈ 19.3) and common silicate gangue minerals (sg ≈ 2.7) such as quartz sand.
