electrowinning gold process

Process of Electrowinning of Gold

The process of electrowinning of gold has the following five advantages: faster electrolysis, lower tailings grade, safe and reliable operation process, high degree of system automation, and good economic benefits. Therefore, it is widely used in gold processing plants.

Kemix Electrowinning

Electrowinning is a process used to recover metals (eg. gold and silver) from concentrated solutions by applying a voltage across electrodes immersed in a concentrated solution. The positive terminal from the rectifier is connected to the anode where the oxidation reactions occur and electrons are generated.

Electrowinning and Smelting Resource Book

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. The process of electrowinning simply involves passing an electric current through the electrolyte (eluate).

Electrowinning Metallurgist & Mineral Processing Engineer

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. The cathodic reaction is: Cu++ + 2e

Electrowinning an overview ScienceDirect Topics

Michael L. Free, Michael Moats, in Treatise on Process Metallurgy: Industrial Processes, 2014. 2.7.3.3.1.1 Electrowinning. Electrowinning is the process of “winning” metal from solution using an applied voltage. Gold electrowinning is usually performed in relatively small vessels or cells that are about 1 m long and contain less than 1 m 3 of solution.

Electrowinning gold processing Rigaku Global Website

After the gold is leached out of the ore, it is typically absorbed onto activated carbon in processes such as Carbon-in-Pulp (CIP), Carbon-in-Leach (CIL), or Carbon Column (CC). Once absorbed, the gold is stripped from the Carbon and the impregnated stripping solution fed into the electrowinning process where the gold is recovered by electrolysis.
