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.

2016-6-10 Until now, flotation has not been successful to recover nickel from laterite ores. • Fine grinding should be used to liberate nickel-containing particles in laterite ores. • Reactor–separator cell with more probability of particle–bubble attachment can help. • Selective flocculation can help to enhance flotation performance of ...

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 ...

2021-10-18 Pyrite particles, having framboidal/altered texture, are known to significantly affect pulp chemistry and adversely affect flotation performance. Therefore, the main objectives of this study were to demonstrate influence of pyrite mineralogy on the flotation of copper (sulphidic) ores and develop alternative conditions to improve the performance.

Started in 2009, the nickel sulphide processing plant has undergone constant modifications, aiming to adapt to the changes in the ore. Main modifications included autogenous grinding converted to semi-autogenous, as well as the installation of a desliming stage aiming to remove ultrafine minerals which reduced the nickel recovery in flotation.

2020-4-8 “For instance, there’s a big debate in the nickel market about where nickel’s going to come from for future electric vehicles. There are two main types of nickel resources: sulphides and laterites (oxides). Flotation can be used to concentrate sulphide nickels up to 30%, whereas laterites cannot be preconcentrated.
