Electrorefining - an overview ScienceDirect Topics

Metals such as gold and platinum, which are insoluble in nitric acid, do not dissolve and report to the anode mud. The production in the anode compartment of a gold-bearing slime, which can cause passivation of the silver anodes, must be periodically removed, creating materials-handling challenges. The anode compartment must be isolated from the cathode compartment by a membrane or porous

Innovations in precious metal recovery

Electrorefining of the gold recovered may also be done in the cell. The system applies to silver as well, and may be adaptable to base and platinum group metals. It could also be used in environmental applications, to remove undesirable metals present in aqueous solution at very low concentration. The work to be discussed forms part of recently filed patent applications. Subsequent and future ...
