A Review on Alternative Gold Recovery Reagents to Cyanide

Gravity concentration process separates the part of ore body that contains gold with higher specific gravity than the host rocks. The effectiveness of gravity concentration arise from the high difference in the specific den-sity between gold, with a density of 19.3 g/cm3, and typical ore which has a density of about 2.6 g/cm3.All grav-
