Chalcocite - an overview | ScienceDirect Topics

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 3 as oxidizing agent and ethylene glycol (EG) as organic solvent).

Bornite - Wikipedia

The copper-lead ores consist of bornite (Bn) and chalcopyrite (Cp) which are both being replaced by twin lamellae textures of chalcocite (Cc) and exsolution of covellite (Cv) after bornite and chalcocite, while covellite veins have been terminated by pyrite (Py).

The sulfide bornite [Cu 5 FeS 4] is also an important copper ore (close to 65% by mass), especially in the copper porphyry deposits. It is Orthorhombic but commonly is massive and/or granular in habit. It does not display the brassy color of pyrite or chalcopyrite until tarnished but is a mottled brown/black/purple to copper-red but often is mixed with chalcopyrite. It easily tarnishes upon ...

copper flotation parameters of chalcocite ore

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).

extraction of copper from chalcopyrite,

The mining of chalcocite has taken place for centuries and is one of the most profitable ores due to its high copper content, which is nearly 80% by weight. Chalcocite has been known to form pseudomorphs of the minerals chalcopyrite, pyrite, enargite, bornite, covellite, millerite, galena and sphalerite.

Chalcopyrite Properties. Chalcopyrite is also known as Peacock Ore because of its lovely iridescent green, blue, pink, purple, and gold colors that resemble the feathers of a peacock. The colors of Chalcopyrite come from the oxidation of copper and iron in the crystal. It's a common mineral that can be found in most sulfide deposits.

Peacock Ore, Bornite Or Chalcopyrite, Peacock Ore

Bornite commonly occurs with other copper sulphide minerals such as chalcocite and weathers, or "oxidizes", to malachite. Chalcopyrite is the most common ore mineral for copper. Chalco comes from the Greek word chalko, meaning copper. Chalcopyrite is commonly found in sulphide deposits in most ore-forming environments.
