Copper extraction by wet chemical method - ScienceDirect

2018-1-1  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).

AN INDUSTRIAL COPPER SOLVENT EXTRACTION PROCESS

2010-7-14  The aim of copper solvent extraction is to concentrate and purify aqueous copper solutions. The process consists of extraction and stripping processes, both of which may contain parallel and series subprocesses. The process has two input flows, pregnant leach solution (PLS) and lean electrolyte (LE), and one recycling flow, the organic solution. In the extraction stage, the copper is extracted from PLS to barren organic (BO) solution. In the stripping stage, copper is stripped from the loaded organic (LO) to lean electrolyte (LE) solution. The result of stripping, i.e. rich electrolyte (RE), is blended and fed to the electrowinning process, where 99,99% pure copper cathodes are produced. A flow diagram of the process
