Bornite Hungarian family) (1742–1791). Bornite Bornite, also known as peacock ore, is a sulfide mineral with chemical composition CuFeS that crystallizes in the orthorhombic system (pseudo-cubic). Bornite has a brown to copper-red color on fresh surfaces that tarnishes to various iridescent shades of blue to purple in places. Its striking iridescence gives it the nickname "peacock copper" or "peacock ore". Bornite is an important copper ore mineral and occurs widely in porphyry copper deposits along with the more common chalcopyrite. Chalcopyrite and bornite are both typically replaced by chalcocite and covellite in the supergene enrichment zone of copper deposits. Bornite is
Rampura Agucha to have occurred approximately 1 billion years ago. There are a few sulphides and oxide minerals that form within the ore that are a particular interest, the major one being sphalerite. Galena, pyrite, pyrrhotite, and marcasite commonly occur with the sphalerite along with some minor arsenopyrite and chalcopyrite. Gahnite and rutile are the most common oxide minerals that form within the ore, with rutile being the most abundant. Graphite is also a mineral that is commonly found within the ore and surrounding rock. Extracted deposits through drilling, blasting, and underground mining methods are loaded and taken to be processed while
