- Chalcocite - Wikipedia
Chalcocite ( ˈkælkəˌsaɪt ), [6][7] copper (I) sulfide (Cu 2 S), is an important copper ore mineral It is opaque and dark gray to black, with a metallic luster
- Chalcocite: Mineral information, data and localities.
Chalcocite easily converts to djurleite under the electron beam through the rearrangement of Cu atoms (Pósfai and Buseck, 1994) Small amounts of the Cu2S phase may deposit from supersaturated volcanic gas, as shown in an experiment (Africano et al , 2002; 300-700oC deposition range for this particular experiment) Compare UM2003-43-S:CuFePdPt
- Chalcocite Mineral Data
Secondary mineral in or near the oxidized zone of copper sulfide deposits Cornwall, England and Butte, Montana Link to MinDat org Location Data From the Greek, meaning chalkos, "copper" Comments: Chalcocite crystals in this specimen vary in size up to 1 2 cm across Location: Bristol nr Hartford, Connecticut, USA Scale: 7 6 x 4 cm
- Chalcocite | Copper Ore, Sulfide Ore, Ore Mining | Britannica
Chalcocite (Cu 2 S) belongs to a group of sulfide minerals formed at relatively low temperatures (see also argentite) Chalcocite alters to native copper and other copper ores

The chalcocite blanket represents a real gold mine, or should that be copper mine, to the copper prospectors Fine crystals of chalcocite are quite uncommon and are much sought after
- Chalcocite: Meaning, Properties, and Uses - Wisdom Of The Spirit
What Is Chalcocite? Chalcocite (pronounced KAL-koh-site) is a copper sulfide mineral with the chemical formula Cu₂S It’s one of the most important ores of copper, prized for its high copper content (nearly 80% by weight)
- Chalcocite - Details and Facts - allmineralsrock
Chalcocite 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
- Chalcocite Cu2S - Handbook of Mineralogy
Occurrence: An uncommon primary hydrothermal mineral but important as a secondary mineral Found in or below the zone of oxidation in hydrothermal veins and in large low-grade porphyry copper orebodies Pyrite, chalcopyrite, covellite, bornite, molybdenite, many other sulfides and their alteration products
