Extraction of Gold using the Electrowinning Process. Elecrowinning is in the meantime a frequently used process whereby gold is extracted without the use of toxic substances. This method uses an electrochemical approach. Here advantage is taken during the extraction of other precious metals such as f.e. copper or zinc where also small ...

Basically the process is supported by two facts, gold is soluble in dilute solutions of cyanide, and second, the pregnant solution can be processed successfully by using zinc powder or activated carbon and electrowinning. In other words, the process involves several steps from crushing until obtaining a Dore bar.

From the extraction efficiencies, it seems as if the conditions for the most effective gold elution were also the conditions for the most effective gold electrowinning. However, in comparing the results of Experiments 2, 3 and 4, in which the gold inlet concentrations were more or less identical, it becomes evident that the electrowinning ...
