Copper is extracted in large amounts from the earth’s crust by mining of sulphide ores and also oxide ores. studies reveal about 80 of copper is produced by its extraction from sulphide ores. chalcopyrite is a certain kind of suphide ore that can be converted to copper by a different method from silicate carbonate or sulphate ores.

Any copperi oxide present will be converted into copperi sulfide during the smelting process because copper has a higher affinity for sulfur than it does for oxygen. for example: cu 2 o fes → cu 2 s feo. impurities form a slag which floats on the surface and is easily removed. one of the reactions to remove iron impurities is shown below:.

Treatment of mixed sulfide oxide ores of copper. there is no possibility of mining the sulfides and the oxides selectively at the new cornelia mine however the oxide and sulfide ores are sharply separated perhaps by an ancient water level so that the oxide ore may be mined and treated in a plant built for that purpose and the underlying sulfide ore may be left for treatment in anoth.
