  • Pyrometallurgical method used for the extraction of copper

    The copper is extracted from sulphide ore by pyrometallurgy which involves reduction of the concentrated ore at high temperature. This process is a dry process. In this process, the sulphide ore is concentrated by froth floatation process. In this process, the sulphide ore is not concentrated by leaching with dil sulphuric acid.

  • Copper extraction by wet chemical method

    Currently the extraction of copper is performed using a pyrometallurgical process that involves the use of electricity as well as coal, both of which are expensive. The use of fossil fuels in extraction produces carbon dioxide which contributes to global warming. The other method used is solvent extraction followed by electro-winning (SX-EW).

    10/3/2013· The method used to extract copper from its ores depends on the nature of the ore. Sulfide ores such as chalcopyrite (C u F e S 2) are converted to copper by a different method from silicate, carbonate or sulfate ores. Chalcopyrite (also known as copper pyrites) and similar sulfide ores are the commonest ores of copper.
