The electrowinning of copper is an electrolytic process that uses electricity to recover dissolved copper from solution as copper plate, also known as 'cathode'. Cu 2+(aq) + 2e - -->Cu (s) (E 0 = +0.34V) Copper easily dissolves in acids including sulphuric, nitric and hydrochloric.
Experimental copper electrowinning was carried out in a continuous solvent extraction/electrowinning pilot plant containing about 37,000 liters of electrowinning electrolyte solution. The temperature of the copper electrowinning solution was kept at 45° C. (+/−1° C.) by means of an electric heater.
Solvent extraction followed by electrowinning (SX–EW) is an economical option for the processing of low-grade and oxidized copper ore. Phenomenological models were developed to simulate the copper SX and the EW processes. The two models were linked together to make a SX–EW simulator.
