Plants processing chromite ore (FeCr204) typically produce tailings or tails, usually in the form of a slurry or slimes stream, containing valuable chromite fines. Recovery of the chromite fines in a cost-effective manner from such slurry or slimes streams is difficult, particularly in respect of -75pm chromite fines.

The desired grade of concentrate was not obtained even at a great sace in recovery. Testwork showed that chromite particles larger than 65-mesh did not respond satisfactorily to flotation. Although the chromite is liberated essentially when the ore is ground to 20-mesh, very poor selectivity resulted in flotation of 48-mesh material.
