The myth of gravity concentration to eliminate mercury use …
Gravity separation in conventional gold processing plants is used to remove relatively coarse gold particles before entering the flotation or cyanidation circuit. While testing a synthetic gold ore in the lab, Lins and Adamian (1993) demonstrated that gold grains up to 0.71 mm can be floated if the turbulence and the pulp density are low.

Gold Gravity Separation
Gold Gravity Separation. The gravity separations are simple and separate mineral particles of different specific gravity. As the density of gold mineral is much bigger than gangue mineral, for the gold mine which has gold particles people often use the gravity separation process. Gravity concentration is a proven process for mineral beneficiation.
