Solution chemistry of sulphide mineral flotation in

2016 7 26&ensp·&enspThe use of low quality water in sulphide minerals flotation plants has been studied widely. However, implementation of the strategy of low fresh water consumption and low process affected water disposal in sulphide flotation requiresprehensive understanding of the impacts of solution chemistry on sulphide minerals flotation.
