Abstract:

Cyaniding gold mud in wet smelting of impurity elements in fluctuation will easily give rise to by-products of smelting of precious metals from copper slag to be excessive，it will affect the recovery of gold refining and directly relate to the economic efficiency of enterprises.In order to improve the recovery of precious metals and increase economic benefits of enterprises，we use the between difference gold，silver and other base metal potential to achieve the objective of separation of gold，silver and base metals through the antioxidant adjustment system potential.From copper in precious metals slag further extraction process is accused of potential chlorinated technology isolated copper-waste liquid containing impurities replacement copper-gold and silver residue further impurity gives silver residue left gold-casting anode place silver electrolytic recovery of silver，with gold grade to deal with high copper slag can finally achieve the separation of gold，silver and bronze to improve the recovery of gold smelting.

Key words: Copper smelting slag, Control potential chlorinated method, Antioxidant, Wet process, Recovery
