    Abstract: An electrochemical system for selective recovery of gold from electronic waste and mining streams includes a vessel configured for flow of fluid therethrough, a working electrode positioned in the vessel, where the working electrode comprises a redox-active metallopolymer, and a counter electrode spaced apart from the working electrode in the vessel. An electrochemical method for selective gold recovery includes selectively electrochemically adsorbing gold complexes from a leach solution onto a redox-active metallopolymer, and electrochemically releasing the gold complexes from the redox-active metallopolymer into a collection fluid.
