The Common Gold Mining Process Gravity Separation

2019-12-4  Gold 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.
