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.
