Introduction to Mineral Processing Chevron Phillips Chemical

Froth flotation is considered to be the most widely used method for ore beneficiation. In ore beneficiation, flotation is a process in which valuable minerals are separated from worthless material or other valuable minerals by inducing them to gather in and on the surface of a froth layer.

Pyrite flotation in the presence of galena. Study on

pyrite decreased in comparison to flotation of individual mineral particles. The zeta potential of galena changed significantly, while that of pyrite increased when two minerals were mixed together. Therefore, interaction of galena with pyrite in flotation significantly affected the flotation recovery of galena.

The role of sodium sulfide in the flotation of pyrite

Flotation tests and Cryo XPS analyses in this study indicate that pyrite may be depressed in copper flotation with the addition of lime despite copper activation occurring on pyrite surface. The hydrophilic calcium and iron oxidation species may form on pyrite surface and be responsible for pyrite depression.
