Oct 12, 2017 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.
Aug 20, 2020 When the smelting process is over, the gold is poured into bars for transport to the next process. In gold extraction, it may have to be refined before being put to use. Refining gold is simply the process of removing the impurities that the smelting process could not remove. There are many gold refining methods.
