Minerals Special Issue : Gravity Concentration

Gravity concentration is at present the main concentration process in the mineral industry in terms of tons processed. The size that can be processed ranges from very coarse materials, coarser than 100 mm, concentrated through heavy media vessels or ROM jigs, to very fine particles, about 10 microns, concentrated through centrifugal processes.

Mineral processing - Wikipedia

It is necessary to determine the suitability of a gravity concentration process before it is employed for concentration of an ore. The concentration criterion is commonly used for this purpose, designated C C {\displaystyle CC} in the following equation (where S G {\displaystyle SG} represents specific gravity ):
