Selective sulphidation and flotation of nickel from a

2013-12-1  Highlights High temperature experiments demonstrated that selective sulphidation is feasible. Sulphides were submicron in size but could be physically upgraded. Nickel sulphides responded to flotation and grades of 6–8% were achieved. Low nickel grade was due to fine particle entrainment. Low nickel recovery was due to issues with fine particle grinding and flotation.

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.

Effect of some process variables on flotability of sulfide

2002-6-1  The results showed that with nickel ores, sulfide flotation is strongly affected by process variables such as grinding media, water quality and oxidation. After using steel mill in grinding, nickel was floated selectively with xanthate in the beginning of flotation but gradually, also pyrrhotite started to float decreasing the selectivity of

Pentlandite oxidation in the flotation of a complex nickel

2011-1-1  ► Nickel recovery was low in the flotation of both fine and coarse fractions in saline water. ► Oxidation occurred on both fine and coarse pentlandite particles. ► NaHS added during grinding improved both pentlandite and serpentine mineral flotation and deteriorated pentlandite separation from serpentine. ► Na 2 S 2 O 4 added during grinding improved pentlandite flotation without affecting
