Abstract

In Sulfide ore flotation, fresh water is normally used as the flotation medium. Due to increasing scarcity of fresh water resources, understanding the effect of use of recycled water/seawater in sulfide ore flotation is essential for its sustainability. The emphasis of this study is to test the possibility of replacement of fresh water with seawater as the flotation medium in sulfide ore flotation. During experiments an increase of 18.9 % and 12.89 % in recovery of Pb and Cu respectively was observed in case of sea water as flotation medium compared to fresh water flotation. However a decrease of 8.55 % and 0.93% in grades of Pb and Cu were observed in case of sea water flotation. It was concluded that seawater can be successfully used in bulk flotation of galena and chalcopyrite from complex sulfide ore by varying the reagents dosages and other flotation variables.
