Bornite is an important copper ore mineral found in many different types of copper deposit.
Peacock Ore, also known as Bornite, is a copper mineral mined in Mexico. Bornite is heavier than an equal volume of chalcopyrite ( 5.1 vs. 4.1) 30th Jan 2010 23:15 GMT Bob Southern.
It can, however, be leached under oxidizing conditions at elevated temperatures or by microbial leaching under low-potential conditions (Gericke, Govender, & Pinches, 2010).This has led to extensive study into leaching of chalcopyrite concentrates as an alternative to smelting. However, the two are often found together and many rocks are a mix of the two. It is Orthorhombic but commonly is massive and/or granular in habit. The sulfide bornite [Cu 5 FeS 4] is also an important copper ore (close to 65% by mass), especially in the copper porphyry deposits. Chalcopyrite is naturally bronze-ish, just like pyrite. Bornite commonly occurs with other copper sulphide minerals such as chalcocite and weathers, or “oxidizes”, to malachite. Leaching of the mixtures of bornite and chalcopyrite at mass ratios of 1:1, 1:3 and 3:1 are performed under various conditions to investigate the possible changes in leaching behaviour in relation to galvanic interactions. The formation of bornite (Cu5FeS4), an iron-deficient sulfide, and its correlation with the slow oxidation rate of chalcopyrite (CuFeS2) in acidic media under atmospheric conditions is demonstrated. Chalcopyrite is essentially unleached under the mild oxidizing conditions of heap leaching (very slow leach kinetics). Key Difference – Pyrite vs Chalcopyrite Pyrite and chalcopyrite are both sulfide minerals, but their chemical composition is different.
this being said, proper chalcopyrite would be a noticeable brassy color, and oftentimes proper untarnished bornite … However, the chalcopyrite you see that looks like bornite has been treated with acid (it is more common than bornite and is often sold as bornite, so be wary of scams). 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. Bornite-Chalcopyrite. The electrochemical dissolution process of chalcopyrite and bornite in acid bacteria culture medium was investigated by electrochemical measurements and X-ray photoelectron spectroscopy (XPS) analysis.
We report the replacement of chalcopyrite by bornite under hydrothermal conditions in solutions containing Cu(I) and hydrosulfide over the temperature range 200–320 °C at autogenous pressures.
