Chalcocite - Wikipedia

Chalcocite (/ 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 an orthorhombic crystal system.. The term chalcocite comes from the alteration of the obsolete name chalcosine, from the Greek khalkos, meaning "copper".

copper (Cu) - David Darling

There are more than 140 naturally occurring copper compounds but only a few of them (chalcopyrite, chalcocite, cuprite, antlerite, azurite, bornite, and malachite) are important as ores from which copper is extracted. Most of them occur only in small quantities.

Well, ok, this is what I've found--some of the confusion lies in the fact that chemically speaking, Chalcopyrite and Bornite are sooooooo close, hold on nah, so I'm gonna go science on ya for a moment--Chalcopyrite is CuFeS 2 with Bornite being Cu 5 FeS 4 both are copper iron sulfides. Both apparently get sold as Peacock Ore with an acid bath.

Chalcopyrite: Mineral Uses and Properties

Associated ore minerals include pyrite, sphalerite, bornite, galena, and chalcocite. Chalcopyrite serves as the copper source for many secondary mineral deposits. Copper is removed from chalcopyrite by weathering or solution, transported a short distance, then redeposited as secondary sulfide, oxide, or carbonate minerals.

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).
