Gold Extraction / Mining |

Extraction of Gold by the Amalgam Process. The amalgam process is the oldest technical method of extracting gold and was used in antiquity. With the amalgam process the gold bearing rock is likewise crushed to fine sand. Afterwards mercury is added to the rock dust. Gold has the property that enables it to join to the surface of the mercury.

Extraction of Gold

The process is applicable directly to gold bearing sand, and to goldbearing rocks after crushing. The crushing is effected by stonecrushers, rollingmills, and stampmills. The washing is carried out either by subjecting the material to the prolonged action of flowing water, or by mechanical agitation with water in deep iron pans or " cradles."
