Copper is extracted from an ore through various methods depending on the nature of the ore of which it is being extracted from For example sulphide ores such as chalcopyrite the commonest ore of copper are converted to copper in a different way than those from silicate carbonate or sulphate ores The most common ore used in the copper extraction is Chalcopyrite CuFeS 2 also recognized as Copper Pyrites and other such sulfides The proportion of copper in the real ore is too limited for straightforward copper extraction to be feasible The concentration of ore is required and the Froth Flotation method is used for this process

The copper is extracted from copper ore by a 7 step process First the ore chalcopyrite in this case is crushed Second a solution is added to the powered rock that makes the copper water repellant and the solution frothy Answer 1 of 2 Copper is extracted from various sulfide ores The most common are bornite and chalcopyrite the others include tetrahedrite native copper covellite chalcotite and some even more uncommon Copper can be theoretically extracted also from secondary copper minerals like malachit

Answer Chalcopyrite is a copper iron sulfide with chemical formula CuFeS2 It is a common ore of copper Pure chalcopyrite contains 346 copper and 349 sulfur and 305 iron It is less desirable than the much rarer covellite CuS which contains 66 copper Chalcopyrite About 80 of all copper extracted comes from sulphide ores A typical ore contains only 05 to 20 copper It is a measure of the value of copper that it is worth extracting it from such small concentrations The ore is a mixture of minerals and rock called gangue The most common copper
