- copper flotation quality
Water quality affects the flotation recovery of minerals and their separation. Mining-process waters become saturated with soluble salts after contact with minerals (oxidation and dissolution) during crushing, classification and flotation. ... Similar results were obtained in the flotation of two copper ores; however, the grade of chalcopyrite ...

For preferential flotation, concentrate quality in the flotation of copper first is much better than that of lead flotation first, which needs a shorter conditioning time and helps to recover copper minerals rapidly, i.e., realizing copper recovery as soon as possible and reducing the separation effects on the coming lead recovery, where copper ...

However, the change in water quality may significantly affect flotation efficiency . The previous study showed that in copper flotation, pyrite recovery was high when freshwater was replaced by seawater partly due to the enhanced Cu(II)-activation of pyrite, making mineral separation even more difficult .

Abstract. Amorphous silica is an abundant gangue mineral in ore deposits, but its effect on mineral flotation is unknown. In this study, the effect of amorphous silica on pulp rheology and chalcopyrite flotation was investigated. It was found that the presence of amorphous silica increased the pulp viscosity more significantly than quartz ...

Surface oxidation of the sulfide minerals negatively affects the flotation performance, i.e., the selectivity and even the recoveries at heavy oxidation conditions. Oxidation may take place during the formation of the ore, during mining and stockpiling, and during the flotation process. Stockpiling of large amounts of ore is a common practice in …
