Chalcocite - Wikipedia
WEBChalcocite (/ ˈ k æ l k ə ˌ s aɪ t /), copper(I) sulfide (Cu 2 S), is an important copper ore mineral. It is opaque and dark gray to black, with a metallic luster. It has a hardness of 2.5–3 on the Mohs scale. It is a sulfide with a monoclinic crystal system. The term chalcocite from the Greek khalkos, meaning "copper".

WEBChalcocite is formed either as a primary vein mineral or, more typically, in supergene deposits where it forms as a result of the redeposition of copper from the breakdown of minerals such as chalcopyrite or bornite.
Chalcocite - Details and Facts
WEBChalcocite is a copper sulfide mineral that has a dark gray to black color and a metallic luster. Its chemical formula is Cu2S, and it has a hardness of 2.5-3 on the Mohs scale. Chalcocite is often found in hydrothermal veins and is associated with other copper sulfide minerals such as chalcopyrite and bornite.
