Metal Recovery From Lead Containing Electrolytes
Last updated:
Abstract:
Valuable metals, and especially copper and silver, are recovered from a lead containing electrolyte in a process in which the electrolyte is fed into an electrochemical polishing reactor that has a high-surface area cathode at which the electrode potential is controlled to so preferentially reduce copper and silver and to form a pre-treated lead-enriched electrolyte that can then be subjected electrochemical lead recovery.
