While sulfide minerals generally are easy to recover by flotation, surface oxidation can have a significant impact on both the recovery and selectivity. The extent of this impact depended upon the mineral type for oxidised Nkomati sulfides (chalcopyrite < pentlandite similar to pyrrhotite). The floatability of these oxidised sulfides has been shown to be restored by sulfidisation with varying degrees of success (chateopyrite
