(1) Chalcopyrite (CuFeS2) Chalcopyrite (including Cu 34.57%) is the most common copper mineral in China's copper mines, has good buoyancy. Chalcopyrite is not easily oxidized, and it can maintain natural floatability for a long time in neutral and weakly alkaline pulps. However, in a strongly alkaline (pH>10) slurry, since the surface is eroded by OH-, a …
