  • Surface properties of copper-sulfide minerals with sodium

    Sep 01, 2020· 1. Introduction. Copper-sulfide minerals, such as chalcocite (Cu 2 S), bornite (Cu 5 FeS 4), and chalcopyrite (CuFeS 2) are important copper resources from copper mines (Fullston et al., 1999).Flotation tends to be used to recover and concentrate these minerals. Flotation is a separation method that uses the surface wettability property (hydrophobicity and hydrophilicity).
