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.

The present application relates to methods for leaching and extraction of precious metals. For example, the present application relates to methods of leaching gold, palladium and/or platinum from a substance comprising gold, palladium and/or platinum (such as a gold-containing ore or a platinum group metal (PGM) concentrate) using an organic solvent that is water-miscible or partially water-miscible.

A method for producing metallic silver by electro-deposition, including electrolyzing an electrolyte solution containing Ce(NO.sub.3).sub.3 in an anode zone and an electrolyte solution containing AgNO.sub.3 in a cathode zone by using an electrolytic cell with a specific diaphragm, wherein the electrolyte solution in the anode zone is not allowed to enter the cathode zone. After the electrolyzing is complete, the metallic silver with a high purity is obtained at the cathode, and a Ce.sup.4+-containing solution is obtained in the anode zone.
