In order to increase the recovery of PGMs by flotation, it is necessary to optimise the liberation of the key minerals in which the platinum group elements (PGEs) are contained which include sulphides, arsenides, tellurides, and ferroalloys among others, while at the same time ensuring the optimal depression of gangue minerals. In order to …
Recover Chromite by Flotation
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.
