A closed-loop electrogenerative recycling process for recovery of silver from a diluted cyanide solution.

A closed-loop process for the complete recovery of silver from a diluted silver cyanide solution has been constructed based on an electrogenerative process. It was shown that the reduction of silver was a mass transport controlled process. Under optimal experimental conditions, 100% of silver was recovered from 500 mg L and 100 mg L silver cyanide solutions by using a reticulated vitreous electrode (RVC) as the cathode.
