THE MINERAL CHALCOCITE. Uses: As a minor ore of copper and as mineral specimens.
Where is chalcocite found?
Chalcocite is sometimes found as a primary vein mineral in hydrothermal veins. However, most chalcocite occurs in the supergene enriched environment below the oxidation zone of copper deposits as a result of the leaching of copper from the oxidized minerals. It is also often found in sedimentary rocks.
How do you identify chalcocite?
Chalcocite (/ˈkælkəˌsaɪt/), 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 2.5–3 on the Mohs scale. It is a sulfide with a monoclinic crystal system.
Where is chalcocite found in the world?
Chalcocite is found nearly all over the world. A classic locality for chalcocite is Cornwall, England, and large, well-formed crystals have come from Australia. In China, and odd new form of the mineral has been found with iridescent root-like growths.

Is chalcocite magnetic?
However, for iron and copper, pyrite and chalcocite are nonmagnetic exceptions, due to physical and chemical considerations. The difference between ferromagnetic pyrrhotite and nonmagnetic pyrite probably is due to chemical orbital attributes.

Which is better chalcopyrite or chalcocite?
It is documented that chalcocite is more reactive than chalcopyrite. (1999) studied the oxidation of different copper minerals using zeta potential measurements, and found that the oxidation of these minerals follows the order: chalcocite > tennantite > enargite > bornite > covellite > chalcopyrite.
