2021-11-1  Chalcopyrite is a common copper sulfide mineral, which is generally recovered via flotation. Pyrite is a common iron sulfide mineral and is often associated with chalcopyrite. The natural floatabilities of pyrite and chalcopyrite are similar, which makes separating them via flotation difficult under weakly alkaline environment.
