Steps Of Extraction Of Copper From Chalcopyrite

We have copper is extracted from the ore chalcopyrite,extraction of copper from sudic ores, either by pyrometallurgy or hydrometallurgy, has various limitations.In this study, a solvometallurgical process for the extraction of copper from suldic ore minerals chalcopyrite, bornite, chalcocite and digenite was developed by using an organic lixiviant fecl 3 as oxi.

Extraction of copper from chalcopyrite

The object of the present invention is the method of extracting copper from chalcopyrite, which is based on the leaching of copper into the solution and subsequent extraction of copper from the above solution. There are a number of proposals on the use of specific intervals of the redox potential for leaching of chalcopyrite. International application PCT/GB97/00585 (WO 98/39491) in the name

Extraction Of Copper Mining, Concentration, Smelting

Copper Smelting means that the concentrated ore is heated strongly with silicon dioxide (silica), calcium carbonate (CaCO 3) and air in a furnace. The major steps in the extraction of copper are Copper in Chalcopyrite is reduced to copper sulphide. Just like in Blast Furnaces, calcium carbonate is added as a flux to create the slag.

Why the Extraction of Copper from Chalcopyrite is so

Sulphide ores such as chalcopyrite are converted to copper by a different method from silicate, carbonate or sulphate ores. So, extraction of Copper from it becomes very difficult & it is a lengthy process because- (i) It contains many impurities in such a high amount that the percentage of Copper in it becomes only 2-3%.
