Sulfide Ores - an overview | ScienceDirect Topics
Froth flotation entails attaching fine Cu-sulfide mineral particles to bubbles and floating them out of a water–ore mixture. The flotation is made selective by using reagents, which make the Cu-sulfide minerals water-repellant (hydrophobic) while leaving the other minerals wetted (hydrophilic). Typical Cu sulfide recoveries to concentrate are ...
