PROCESS FOR ELECTROREFINING OF GOLD BY NON-AQUEOUS ELECTROLYSIS

摘要

The present invention relates to a method to electrolyze and refine gold through non-aqueous electrolysis, capable of manufacturing high purity gold by setting gold, containing impurities or gold alloy scrap as an anode; and electrochemically dissolving the same in a non-aqueous solution forming an electrolytic cell having conductivity while at the same time returning the same to a cathode. In order to improve an efficiency of electrolysis, the present invention improves an electrolyte and an electrolysis condition. As such, the present invention is capable of directly refining gold through electrolysis at low temperatures when refining low purity gold; consecutively refining the gold by changing the low purity gold or gold alloy scrap; and minimizing energy consumption.
