Copper Ores Chalcopyrite Bornite Chalcocite Triturador De Martillo

Sulphide ores such as chalcopyrite are converted to copper by a different method from silicate, carbonate or sulphate ores. 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,

Following are the list of minerals that serve as copper ores in the copper mining process: Name Formula % Copper when pure Chalcopyrite: CuFeS 2: 34.5: Chalcocite: Cu 2 S: 79.8: Covellite: CuS: 66.5: Bornite: 2Cu 2 S·CuS·FeS: 63.3: Tetrahedrite: Cu 3 SbS 3 + x(Fe,Zn) 6 Sb 2 S 9: 32–45: Digenite: Cu 9 S 5: 78.1: Malachite: CuCO 3,

02-01-2022· Bornite is an important copper ore mineral and is often found in porphyry copper deposits along with the more common chalcopyrite. Chalcopyrite and bornite are generally replaced by chalcocite and covellite in the supergenic enrichment area of copper deposits. Is Chalcopyrite The Same As Peacock Mineral?

Copper concentrate is mixed with iron and a fusible salt or fusible salt mixture which is molten at the roasting temperature. The mixture is roasted in a non-oxidizing atmosphere at a temperature below 475*C (preferably between 350*C-390*C) to produce a product containing free copper and pyrrhotite. The salt acts as a solvent for the reaction and enables copper to be recovered

04-03-2019· Bornite is frequently compact, granular, or massive and alters readily to chalcocite and other copper minerals upon weathering. It forms mainly in hydrothermal copper ore deposits with minerals such as chalcopyrite , pyrite marcasite , and quartz .

The copper is naturally present in a broad variety of copper bearing sulfide minerals, mainly primary sulfides (i.e. Chalcopyrite and Bornite) and secondary sulfides (i.e. Chalcocite and Covellite). Figure 1 shows the main copper ore bodies world-wide.

28-04-2019· Dec 13, 2019· Extraction of copper from sufidic ores, either by pyrometallurgy or hydrometallurgy, has various limitations. 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

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 metamorphic skarn deposits, in pegmatites and in sedimentary cupriferous shales.

SULPHIDE COPPER ORES. The prin cipal sulphide copper ores of the United States are chalcocite or copper glance (Cu,S), con taining 79.8 per cent of metallic copper ; enargite (CuaAsS,), 48.3 per cent; covellite (CuS), 66.4 per cent; chalcopyrite or copper pyrites (CuFeS,), 34.5 per cent; bornite or peacock ore (CtuFeS4), 50 to 70 per cent.

13-06-2016· When chalcocite is leached with ferric sulphate one-half of the copper dissolves rapidly leaving a residue approximating CuS which dissolves much slower; with bornite the copper is attacked preferentially to the iron; while with chalcopyrite the mineral dissolves as chalcopyrite; that is, at any stage in the dissolution (up to an extraction of approximately 45

Bornite is easily recognized because it tarnishes to iridescent shades of blue, purple, red, green and yellow. It is commonly called "peacock ore" or "purple copper ore" after these iridescent colors. Upon surface exposure, bornite will weather to chalcocite or other copper minerals. Bornite is a popular and fast-selling mineral specimen at,

09-06-2020· A thermodynamic and kinetic model is proposed to explain the formation of bornite, chalcopyrite, and magnetite during partial roasting of enargite-containing copper concentrates. The proposed mechanism involves solid–solid–gas and solid–gas reactions between chalcocite, pyrrhotite, gaseous sulfur, and oxygen. Bornite formation could be explained through a
