A process was developed for recovering gold and refining sn-pb solders from scrap solder discarded by the electronics industry. Contaminated solder can be treated by electrorefining in a molten- chloride system, yielding refined solder at the cathode and a high concentration of gold and other metal impurities at the anode. Subsequent recovery of gold from the anode bullion is by conventional fire refining.
