Nickel beneficiation process,process design for ...

15/09/2020  Nickel ore is mainly divided into copper-nickel sulfide ore and nickel oxide ore, and their beneficiation and processing methods are completely different. The most important method for beneficiation of copper-nickel sulfide ore is flotation, while magnetic separation and gravity separation are usually auxiliary beneficiation methods.

NICKEL AND COBALT ORES: FLOTATION - 911 Metallurgist

Developments in Flotation Flotation of Nickel Sul\de Minerals Collectorless Wotation It is known that chalcopyrite and pyrrhotite can be Soated without collectors at electrode potentials of #400 mV and #50 mV respectively, and pyrite does not Soat even at #700 mV. The underlying mechanism causing hy-drophobicity, although obscure, is attributed to sur-face oxidation, formation of elemental ...

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. The ore was ground to 70% passing 75 microns.
