Chalcocite (UK: /ˈkælkəˌsaɪt/[5]), copper(I) sulfide (Cu2S), is an important copper ore mineral. It is opaque and dark-gray to black with a metallic luster. It has a hardness of 2 1⁄2 - 3 on the Mohs scale. It is a sulfide with an orthorhombic crystal system. The term chalcocite comes from the alteration of the obsolete name chalcosine ...

1. Introduction After chalcopyrite, bornite (Cu 5 FeS 4) is among the most common Cu-sulfides.Bornite is a major Cu-carrier in many high-sulfidation epithermal deposits (White and Hedenquist, 1990), sedimentary-hosted copper deposits such as the Kupferschiefer of northern Europe (e.g., Piestrzynski and Sawlowicz, 1999) and some porphyry–Cu …
