Effects of Galvanic Interaction on Collectorless Flotation

Galvanic interactions between sulfide minerals have significant effects on their electrochemistry and flotation behavior. The effects of galena and pyrite on their collectorless flotation behavior have been studied in this paper. The results showed that galvanic interaction between galena and pyrite would occur when they were mixed. In the
