Gold Electrolysis Process & Gold Recovery

2015-1-7  Because of if gold lost heat, gold will adhere with the crucible. If you use electric crucible or ceramic crucible, when gold was melt pour into the block. A high percentage of gold is round and glossy. This pure of gold is 98.2% If you want gold cleaner, you can boil with nitric acid about 10-20 minutes.

Gold Recovery from Scrap Electronic Solders by Fused

2015-12-28  A process was developed for recovering gold and refining Sn-Pb solders from scrap solder discarded by the electronics industry. During assembly of electronic systems, gold and other contaminant metals are introduced into solder baths which are periodically discarded. Contaminated solder can be treated by electrorefining in a molten-chloride system, yielding refined solder at the cathode and a
