The Common Gold Mining Process – Gravity Separation Method

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

Gravity Separation - an overview ScienceDirect Topics

Gravity separation has been applied to process chrome slag by steel researchers in India. Heavy media separation (Choudhury et al., 1996) and crushing and jigging (Khan et al., 2001) are the principal techniques used. The slag is subjected to 2-stage crushing to reduce the size to −10 mm and then screened into −10 +1 mm and −1 mm fractions.

The Common Gold Mining Process – Gravity Separation Method

In the sand gold deposits, the gold usually exists in the form of monomer natural gold, and its particle size is generally more than 16t/m 3, which has a big difference with gangue density, so gravity separation method is the most effective and economic gold mining process. However, gravity separation method is rarely used alone in the lode gold mining. Generally, adopting the jigging
