Flotation performance Factorial design abstract A major challenge in the processing of PGM-bearing UG2 ore is the fact that it is comprised largely of chromite (60–90% by volume). Chromite is generally not naturally floatable but significant quantities report to the concentrate by entrainment.

The chromite entrainment was significantly reduced (>30 % ...

deposits. Since UG-2 ore has a high chromite (FeO.Cr2O3) content, the reduction of the chromium oxide (Cr2O3) recovery in the final flotation concentrate is crucial to the smelting process, as the smelter furnace feed can operate effectively with an upper limit of about 2.5 % Cr2O3 (Hay and Roy, 2010).
