The Electrowinning Process: Part One :: Total Materia Article. An electrowinning unit has three main components: (1) an electrolytic cell, (2) a rectifier, and (3) a pump. The electrolytic cell and rectifier are shown in Figure 1. An electrolytic cell is a tank in which cathodes and anodes are typically arranged in alternating order (see Figure 2).

Electrowinning is defined as the cathodic deposition of metal, in this example copper, from a copper bearing solution by the passage of an electric current current using an insoluble anode.. For copper the electrowinning reaction reaction is: CuSO4 + H2O ⇒ Cu + ½O2 + H2SO4. The overall reaction is the combination of two electrochemical half reactions.

By pressurising the electrowinning cell, the gold-cyanide complex in electrowinning is destabilised and increases the electrowinning efficiency, lowering solution tenors returning back to the elution column and providing the optimal kinetics for rapid eluting of the precious metals off the loaded carbon.

Electrowinning is the recovery of metals, such as gold and silver, from solution by passing a current through the solution. Electrons from the current chemically reduce the gold and/or silver ions, to form a solid metal compound on the cathode. ... Oversize particles can choke pumps, block gravity units, rapidly wear out equipment, and reduce ...

A relatively high concentration of metal in solution also is needed for conventional electrowinning processes to operate efficiently. Electrowinning can recover 90 to 95% of the available metals, but it is known to operate efficiently only at high metal concentrations. This is especially true when flat plate cathodes are used.
