concentration criterion gravity separation

Gravity Separation - ScienceDirect

2016-1-1  To determine the suitability of gravity separation processes to a particular ore type, a concentration criterion is commonly used. A concentration criterion (CC) can be defined as (16.1) Concentration Criterion = SG of heavy mineral − SG of fluid SG of light mineral − SG of fluid where SG = specific gravity (or density), and the fluid is typically water or air.
