Title:
DEVICES AND METHODS OF COPPER RECOVERY
Document Type and Number:
WIPO Patent Application WO2008039478
Kind Code:
B1
Abstract:
Contemplated configurations and methods allow for effective removal of copper from aqueous media by selectively concentrating copper in a first stage, wherein competing metal ions are subjected to a redox reaction to thereby increase selective concentration. Copper is then plated in a flow through electrode from a relatively concentrated copper solution that is depleted from competing non-copper metals. In preferred aspects, the first stage provides a copper-depleted effluent that includes zinc and/or manganese for further recovery.
