01/01/2018· 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). This method is applied in Zambia, the

Hydrometallurgy is an alternative method for copper extraction from chalcopyrite, which can be applied to low grade copper ores due to the lower operating costs.2 Many works have been reported for hydrometallurgical leaching of chalcopyrite. The most often used lixiviants are acidic chloride media, acidic sulfate media and basic ammonia solutions, together with various oxidizing agents.3–7
