Gravity concentration separates minerals based on differences in specific gravity. Specific gravity is the weight of the same volume of material compared to water, where the specific gravity of water equals 1. The specific gravity of gold is 19.3, so it is 19.3 times as dense as water. When separating free gold from a typical quartz deposit, gravity concentration must separate based on specific gravities of 19.3 and
