Aug 07, 2012· 2) As to the statement that 'chalcocite is easily leached' testwork was done on different purified and milled copper sulphides, using the empirical conditions obtaining in Nchanga leach circuits, to quantify leaching characteristics. About 15% chalcocite leached compared to only about 5% chalcopyrite. Delete

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.

Pulp Densities. Pulp densities indicate by means of a tabulation the percentages of solids (or liquid-to-solid ratio) in a sample of pulp. This figure is valuable in two ways—directly, because for each unit process and operation in milling the optimum pulp density must be established and maintained, and indirectly, because certain important tonnage calculations are based on pulp density.

May 02, 2019· 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

Energetically speaking, Chalcopyrite's vibrational action is said to be stronger than that of Bornite. 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.

Roughly 90 percent of the copper value occurred primarily as chalcocite (Cu2S), with minor quantities of cuprite (Cu2O), covellite (CuS), chalcopyrite (CuFeS2) and bornite (Cu5FeS4). The remaining 10 percent was present as native copper. The major gangue mineral was quartz but there were significant quantities of kaolinite and sericite as well.

A typical concentrate of chalcocite can grade between 37% and 40% copper in sulfide, making them relatively cheap to smelt compared to chalcopyrite concentrates. Some supergene sulfide deposits can be leached using a bacterial oxidation heap leach process to oxidize the sulfides to sulfuric acid, which also allows for simultaneous leaching with ...

Chalcocite forms from the alteration of other minerals, especially other copper sulfides such as Bornite, Covellite, and Chalcopyrite, and may also form pseudomorphs after these minerals. It often forms in association with Chrysocolla, with the Chrysocolla forming as an alteration around the Chalcocite.Chalcocite is named after the Greek word chalcos, which means "copper" in Greek, in …

The chalcocite zone contains very rich (up to 15% Cu) chalcocite mineralisation, with some primary ore intrusion. The primary ore is chalcopyrite mineralisation in a range of rock types. Both pyrite and magnetite are dispersed through the three ore types, to varying amounts. The pyrite contains the majority of …

Before studying the separation of chalcopyrite and chalcocite from pyrite, the floatability of single copper minerals in the absence of pyrite was investigated. In order to simulate normal flotation circuits in plants, in this study, chalcopyrite and chalcocite recovery were maximized in rougher flotation by using stainless steel media in ...

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 ...

which belong to the sulfidic ores such as chalcopyrite, bornite, covellite, digenite and chalcocite.
