Abstract/Summary Mineral processing operations, in particular flotation, need substantial amount of water to carry out their activities. However, many of these operations are located in places where water is in short supply or economic developments are putting water supplies under pressure. Using low quality water for flotation is increasingly common in mineral processing plants around the world which has implication on performance of both valuable and gangue minerals. Therefore, understanding the effect of different ions present in water on the various flotation sub-processes in both froth and pulp zones is necessary to manage low quality water and to achieve desired separation efficiencies. Researchers have shown that copper sulfide minerals, such as, chalcocite and chalcopyrite float well, both in salty water and seawater. On the other hand, there is evidence that flotation of chalcopyrite reduces in the presence of aluminium and iron species in solution. It has also been shown that multi-valence ions such as Al3+ and Ca2+ are more influential on froth stability than single valence ions such as Na+. This paper reviews previous work conducted in this area and highlights the interactions and implication of using low quality water in sulfide mineral flotation.
