Gold Ore Gravity Concentration by sluice Henan

2021-3-21  Gravity concentration is a process to concentrate the gold mineral of interest using the difference of specific gravity of gold and gangue minerals. The specific gravity of gold is 19.5 and the specific gravity of quartz (the common gangue mineral associated with gold) is 2.65 (i.e., gravity concentration works because gold is heavy, and quartz is light).

Gravity Concentration - an overview ScienceDirect

In the various gold rushes of the nineteenth century, many prospectors used gold panning as a means to make their fortune—another ancient method of gravity concentration. Gravity concentration, or density-based separation methods, declined in importance in the first half of the twentieth century due to the development of froth flotation, which allowed for the selective treatment of low-grade complex ores.
