Sulfides froth flotation reagents

This froth flotation method is used to treat quartz sulfide ores or goldsilverbearing pyrite and pyrrhotite containing gold telluride pyrrhotite chalcopyrite and other sulfide minerals The floatable gold telluride in the ores is first produced as a concentrate and then roasted and cyanided to expose gold and silver ores in sulfides and tellurides
