Gravity Concentration Of Chromium Ores

  • 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 ):
