"Solvent extraction followed by electrowinning (SXEW) is an economical option for the processing of low grade and oxidized copper ore. Phenomenological models were developed to simulate the copper solvent extraction and the electrowinning processes. The two models were linked together to make a SX/EW simulator. The simulator is used to predict the operation of …

A combination of hydrometallurgical processes of high-pressure oxidative leaching (HPOL), solvent extraction (SX), and electrowinning (EW) were utilized to recover copper from mine tailings which contain about 0.3% Cu content. The HPOL process yielded a high copper leaching rate of 94.4% when water was used as a leaching medium.

attain the extraction desired. An SX-EW operation is an acid plant. It takes copper out of solution and replaces it with protons which make their way, via the organic extractant, back to the raffinate stream. In heap leach operations the acid is consumed during leaching. In a concentrate leach scenario, it may be more difficult to integrate the
