Gravity Concentration

Gravity concentration process that exploits the differ-ences in densities of minerals to bring about a separ-ation is the oldest beneficiation method known to
mankind. Although with the advent of froth flotation, the relative importance of gravity concentration has declined in twentieth century, on an average higher tonnage of material is still treated by gravity concentration than flotation. It finds diverse applications in the treatment of coal, beach sands, iron, gold, diamonds platinum, barite, fluorspar, tin, tungsten ores etc. The gravity separation processes are comparatively cheaper and enviro-nment friendly.
