Bornite is an important copper ore mineral and occurs widely in porphyry copper deposits along with the 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.

Extraction Of Copper From Chalcopyrite

Extraction Of Copper From Chalcopyrite

About 3 4 th of Copper (Cu) produced in the world has come from Chalcopyrite (CuFeS 2) but it is the lowest standard ore of Copper. The method used to extract copper from its ores depends on the nature of the ore. Sulphide ores such as chalcopyrite are converted to copper by a different method from silicate carbonate or sulphate ores.

Chalcocite forms from the alteration of other minerals, especially other copper sulfides such as Bornite, Covellite, and Chalcopyrite, and may also form pseudomorph s after these minerals. It often forms in association with Chrysocolla, with the Chrysocolla forming as an alteration around the Chalcocite.

Mar 29, 2016 Chalcopyrite is a copper iron sulfide mineral, and its chemical formula is CuFeS2. This mineral is naturally presented in a variety of ores from huge masses to irregular veins and it is considered as the most important copper ore. Chalcopyrite oxidizes to several types of oxides, hydroxides, and sulfates when it is exposed to the air.
