Bornite is an important copper ore mineral found in many different types of copper deposit. It is also known as peacock ore because of its iridescent purple-blue-green tarnish. Fresh bornite, however, is copper red. Bornite commonly occurs with other copper sulphide minerals such as chalcocite and weathers, or "oxidizes", to malachite. Originally included with kupferkies in 1725 by Johann Friedrich Henckel. Later assigned various multi-word Latin names by Johan Gottschalk Wallerius in 1747 and variously further translated including purple copper ore and variegated copper ore in 1802 by Rene Just Hay. Also called as buntkupfererz by Abraham Gottlieb Werner in 1791.

Origins of Chalcocite Defined by Copper Isotope Values

30-8-2017Copper in chalcocite that is associated with hypogene hydrothermal ores is derived from a magmatic hydrothermal fluid or is extracted from country rocks at high temperatures. Moreover, extensive studies showed that hypogene hydrothermal copper minerals such as chalcopyrite and bornite do not display appreciable fractionation (1) [7–11].

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).

Chalcocite, copper(I) sulfide (Cu 2 S), is an important copper ore mineral. 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.

Bornite is mined with chalcopyrite and other copper compounds as an ore of this metal. Return To the Mineral Collectors Information Page Please note that the author, Chris Ralph, retains all copyrights to this entire document and it may not be reproduced, quoted or copied without permission.

What's in an ore? There are many types of copper ore found throughout the world. Picture 4 shows the distribution of these deposits. About 80% of all copper extracted comes from sulphide ores. A typical ore contains only 0.5% to 2.0% copper. It is a measure of the value of copper that it is worth extracting it from such small concentrations.

The most valuable commercial accumulations of chalcocite are associated with the zones of oxidation of copper deposits, where chalcocite is found in association with bornite, chalcopyrite, and other sulfides (deposits at Bisbee, Ariz., and Butte, Mont., in the United States, at Braden and Chuquicamata in Chile, at Tsumeb in southwestern Africa
