Gravity separation.

Gravity separation is used for coal, metalliferous ores and industrial minerals. In the case of coal, the required product is the lighter mineral and the difference in relative density between the coal and the shale reject is comparatively small. In contrast, for galena, cassiterite or native gold the wanted minerals are the heavy ones and the differences in density between them and the gangue
