Metal Recovery Processes
In copper electrowinning, the difference between the cathodic (E o = 0.34 V) and anodic (E o = 1.23 V) potentials is approximately 0.9 V. The anodic overpotential is usually 0.2–1.0 V. ... The first applied potential option is a low voltage. A low voltage may be sufficient to deposit only the more noble metal. An optimum applied voltage will ...

SX EW Capital & Operating Cost of Solvent Extraction & Electrowinning
As a result each mixer settler is ½ the size of those in the 2×1 circuit and the total settler area is only 66.7% of that of the 2×1 circuit. The cost saving is estimated to be about 29% which gives a capital cost of $5.0 million. The electrowinning capital cost is the same for each plant and is based on a copper production of 27.2 tonnes/day.
