US4083921A - Purifying molybdenum flotation concentrates ...

Copper, iron, and lead impurities are removed from concentrates by mixing the feed concentrates with a nonvolatile chloride salt, heating the mixture to a temperature of from about 200° to 350° C for a time sufficient to activate the lead impurities in the concentrates so that they can be leached therefrom during the subsequent leach step, and leaching copper, iron, and ...

Molybdenite flotation from copper/molybdenum concentrates ...

Typically, rougher molybdenite and recovery from bulk copper/ concentrates involves the use of alkalisulfides, Nokes reagents, cyanides, oxidants, and/or thermal treatment to depress copper sulfide minerals. The bulk copper/ feed generally varies from 0.2% to 1.0% , and with traditional reagents the single-stage rougher recovery of molybdenite ...
