Gold gravity separation makes use of gravity forces of materials with different density and difference of mineral granules to enrich gold from the ore. Gravity separation is widely used in gold enrichment for both placer gold ore and rock gold ore. Gravity separation can separate gold from the impurities because there is a big density
