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.
