Frequently Asked Questions

How does electrowinning work?

In electrowinning, a current is passed from an inert anode through a liquid leach solution containing the metal so that the metal is extracted as it is deposited in an electroplating process onto the cathode.

What is electrowinning of copper?

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

What is electrowinning of gold?

Process of electrowinning of gold, also called electric extraction, is a process of recovering gold by desorption electrolysis of gold loaded carbon under high temperature and high pressure conditions. It is an important part in the gold cyanidation process.

What is electrowinning and smelting?

Electrowinning and smelting are the final stages of gold production. The concentrated gold solutions produced in the elution circuit (pregnant eluate and by the Sunrise Reactor, are passed through the electrowinning cells which converts the gold ions (charged gold particles) in the solution into solid gold.
