The Common Gold Mining Process – Gravity Separation Method .

Gravity separation method is to separate the minerals according to their relative density (usually called specific gravity). The mineral particles with different densities are subject to hydrodynamic and mechanical forces in the moving medium (water, air and heavy liquid), resulting in suitable conditions for loose layering and separation, thus separating ore particles with different densities

Heavy Liquid Testing Procedure

The general procedure is as follows. The sample is placed in the liquid of lowest specific gravity and is split into two fractions. The float fraction is set aside to be weighed and assayed. The sinks fraction is washed in a suitable solvent, dried and placed in the liquid of a higher specific gravity. This process is continued in steps of suitable S.G. differences until a small final sinks .
