Effect Of Oxide Ores On Flotation Of Copper Sulphide Minerals

Oct 27, 2020 Almost all copper sulphide ores contain iron bearing sulfides, so in a sense, the flotation of copper sulfide is essentially the separation of copper sulfide from iron sulfide. The common iron sulfide minerals in copper ore are pyrite and pyrrhotite. Chalcopyrite a kind of copper oxide ore.
