Copper Ore Chalcocite Bornite
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.

copper ore chalcocite bornite Manufacture of copper About 80% of the worlds primary copper comes from ores in which copper is present as a sulfide mineral for example chalcopyrite (CuFeS 2) (the most abundant copper ore) bornite (Cu 5 FeS 4) and chalcocite (Cu …
Chalcocite - an overview | ScienceDirect Topics
Copper is most commonly present in the earths crust as coppereironesulfide and copper sulfide minerals, such as chalcopyrite (CuFeS 2) and chalcocite (Cu2 S). The concentration of these minerals in an ore body is low. Typical copper ores contain from 0.5% Cu to 1 or 2% Cu.

Natural Chalcopyrite is described as a brassy yellow or gold tarnishing to multicolor, a copper ore mixed with iron looks very much like Pyrite, the 2nd part of the name. The first part of the name, Chalco, comes from the Greek word for brass.
Chalcocite: The mineral Chalcocite information and pictures
Chalcocite forms from the alteration of other minerals, especially other copper sulfides such as Bornite, Covellite, and Chalcopyrite, and may also form pseudomorph s after these minerals. It often forms in association with Chrysocolla, with the Chrysocolla forming as an alteration around the Chalcocite.

CHALCOCITE (Copper Sulfide)
Chalcocite is an important copper mineral ore. It has been mined for centuries and is one of the most profitable copper ores. The reasons for this is its high copper content (67% atomic ratio and nearly 80% by weight) and the ease at which copper can be separated from sulfur. It is not however the primary ore of copper due to its scarcity.

Chalcopyrite - Wikipedia
Associated copper minerals include the sulfides bornite(Cu5FeS4), chalcocite(Cu2S), covellite(CuS), digenite(Cu9S5); carbonates such as malachiteand azurite, and rarely oxides such as cuprite(Cu2O). Is rarely found in association with native copper. Chalcopyrite is a conductor of electricity.

In this study, a solvometallurgical process for the extraction of copper from sulfidic ore minerals (chalcopyrite, bornite, chalcocite and digenite) was developed by using an organic lixiviant (FeCl 3as oxi- dizing agent and ethylene glycol (EG) as organic solvent).
Chalcocite - Wikipedia
Chalcocite (UK: / 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 1 ⁄ 2 - 3 on the Mohs scale.It is a sulfide with an orthorhombic crystal system.
