Copper can be extracted from various types of ores, most of which belong to the sulfidic ores such as chalcopyrite, bornite, covellite, digenite and chalcocite. Chalcopyrite is the most common copper bearing mineral and accounts for approxi mately 70% of the copper deposits in the world.1 At present,
Chalcocite is an important copper mineral ore. It has been mined for centuries and is one of the most profitable copper ores. The reasons for this is its high copper content and the ease at which copper can be separated from sulfur.

Copper is a chalcophile element forming several minerals, including chalcopyrite, chalcocite, covellite, Bornite, tetrahedrite, Digenite, and malachite, Azurite, cuprite, chrysocolla, tennantite and dioptase but is more widely dispersed at trace levels in mica , pyroxene and amphibole, thus showing a greater affinity for mafic than for felsic igneous rocks.
Copper is most commonly present in the earth39;s crust as copperironsulfide and copper sulfide minerals, for example, chalcopyrite , bornite , and chalcocite . The concentrations of these minerals in an ore body are low. Typical copper ores contain from 0.5% Cu to 12% Cu .
chalcopyrite and other copper sulfides are completely if covellite chalcocite ores contain bornite, this mineral also appears in slags List Of Copper Ores following are the list of minerals that serve as copper ores in the copper mining process: name, formula, copper when pure. min chalcopyrite.jpg.
