Due to scarcity of fresh water and stringent regulations on the quality of discharged water, more and more flotation plants have to use groundwater, sea water or recycle water with a high concentration of electrolytes. Although a number of studies have been conducted to investigate the effect of saline water (or salt solutions) on mineral flotation, effective ways to solve the problems encountered in mineral flotation plants using saline water are currently not available. This paper presents a review of published articles addressing the effect of saline water on the interfacial phenomena taking place in the flotation process, such as surface wettability, bubble-particle collision and attachment, mineral particle interactions and frothing. This review provides an overall picture of the current status of studies in this area and pinpoints directions of future research to address different problems associated with using saline water in mineral flotation.
