    Abstract. In this work, the E h pCl diagram of the CuCl H 2 O system was established, and the kinetics of copper dissolution in cupric chloride solution were studied with an emphasis on possible difficulties that may occur during copper electrowinning. The results were used to guide an investigation of copper electrowinning from cupric chloride solution.
