Bornite - Wikipedia

Bornite is an important copper ore mineral and occurs widely in porphyry copper deposits along with the more common chalcopyrite. Chalcopyrite and bornite are both typically replaced by chalcocite and covellite in the supergene enrichment zone of copper deposits. Bornite is also found as disseminations in mafic igneous rocks, in contact ...

Chalcocite - an overview ScienceDirect Topics

Copper is most commonly present in the earth's crust as copper–iron–sulfide and copper sulfide minerals, for example, chalcopyrite (CuFeS 2), bornite (Cu 5 FeS 4), and chalcocite (Cu 2 S). The concentrations of these minerals in an ore body are low. Typical copper ores contain from 0.5% Cu (open-pit mines) to 1−2% Cu (underground mines).

Formula: Cu 2 S Monoclinic Description: Chalcocite 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 is distinguished with difficulty from digenite (Cu 9 S 5) and djurleite (Cu 31 S 16), both of which may form by the leaching of ...
