Copper Ore Chalcocite Bornite

Copper Ore Chalcocite Bornite. Bornite is a type of copper ore, known for its iridescence. Peacock ore is sold to amateur mineral collectors and tourists, and is usually marked as a variety of bornite. In fact, however, most peacock ores are acid treated chalcopyrite, which produces a strongly colored variegated bornite named after Ignatius von ...

Bornite - Wikipedia

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 also found as disseminations in mafic igneous rocks, in contact metamorphic skarn deposits, in pegmatites and in sedimentary cupriferous shales. It is i
