201611 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.

Gravity Separation  an overview ScienceDirect Topics
The separation distance between particles decreases as the concentration criterion decrease and thus separation should become more difficult with decreasing concentration criterion. If the particles don’t reach their terminal velocities then the separation distance between particles is reduced.
