nickel sulphide grinding

A review of the effects of the grinding environment

2011-7-8  In a recent study (Greet et al., 2008a) with a nickel sulphide ore, a laboratory Magotteaux Mill® and a CSIRO on-line UV reagent monitoring system were used in grinding tests with different media types and xanthate additions to the mill. The total xanthate levels in the grinding pulp were analysed in situ as a function of grinding time.

Flotation of Nickel-Copper Sulphide Ore: Optimisation of

2020-1-8  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.
