Electrolytic processes for gold and other precious metals ...

Electrolytic Methods Used in Refining Processes of Gold and Other Precious Metals. Electrolysis is an electro-chemical process where an electrical current stream is flowing between two electrodes and through an electrolyte.This process involves the transfer of metal ions through the ionised electrolyte solution, depositing positive ions on the cathode and negative ions on the anode.
