Although iodide lixiviants have been reported to be highly effective at leaching Au from WPCBs, there remains an issue on how to recover Au from WPCB iodide leachates in an efficient and economically feasible manner. , Previous authors have reported the high yield (> 99 %) recovery of Au from WPCB iodide leachates by reductive precipitation under highly acidic (pH < 1.6) and alkaline conditions (pH > 13) induced by 0.1 M ascorbic acid and 0.1 M sodium hydroxide respectively. However, considering the complex metal compositions of WPCB iodide leachates, extensive co-precipitation of impurities is expected to occur, resulting in the need for further beneficiation. Moreover, strongly alkaline, and acidic precipitation reagents are highly corrosive and thus necessitate the use of expensive corrosion resistant equipment. , Hence, there is a need to develop a more efficient and less problematic process for Au recovery from WPCB iodide leachates. The present work uses a laboratory experiment to investigate the feasibility of Au recovery from WPCB iodide leachates using a novel membranebased electrowinning process.
