Flotation of Nickel-Copper Sulphide Ore: Optimisation of ...

The nickel-copper sulphide ore used in this study was supplied by Trojan Nickel Mine located in Bindura, Zimbabwe. From the X-ray diffraction analysis, the main phases present in the ore were pentlandite (49.4%), pyrrhotite (41.2%) and quartz (4.6%), Fig.1. The ore which was supplied in lumpy form was subjected to crushing and grinding.
