What are the chemical or physical separation methods used

Physical separation usually involves the difference in mass between gold and most of the other associated minerals. Once the gold is physically separated from the host material and of a relatively similar size it can be separated using a rotary bowl spinning at high speed with water to fluidize the material, a shaking table or spirals.
