    Solvent extraction for copper was first achieved commercially by use of weak ketoxime reagents which exhibited many limitations in terms of strength selectivity phase disengagement and in some cases stability. The more recently developed salicylaldoximes are very strong and highly selective and they possess very rapid kinetics.

    Copper Mining and Production Processes Explained

    Leaching offers an alternative to copper mining. First the ore is treated with dilute sulphuric acid. This trickles slowly down through the ore over a period of months dissolving copper to form a weak solution of copper sulphate. The copper is then recovered by electrolysis. This process is known as SX-EW solvent extractionelectrowinning.
