Why the Extraction of Copper from Chalcopyrite is so,

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. 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,

The commonest ore used in the extraction of copper is Chalcopyrite (CuFeS 2) also known as Copper Pyrites and other such sulphides. The percentage of copper in the actual ore is too low for direct extraction of copper to be viable. The concentration of ore is required and it is done by the Froth Flotation method.

Abstract Three oxidants, hypochlorous acid, chlorate and nitrate, were assessed for their ability to oxidise chalcopyrite (CuFeS2). Hypochlorous acid was the most aggressive oxidant trialled, with copper extraction reaching a plateau after 1–5 h. Extraction in this system was complete at room temperature when reagent concentrations of 0.3–0.4 M were supplied.
