ABSTRACT
Enargite (Cu3AsS4) is a representative copper-arsenic sulphide mineral. It occurs locally in some ore deposits, especially epithermal high sulphidation deposits (Arribas, 1995) and porphyry copper systems (Lattanzi et al., 2008). Although enargite is also valuable as a copper resource, the arsenic in the mineral makes it environmentally toxic through emissions associated with smelting (Dutré and Vandecasteele, 1995).
