Metal Recovery Processes

Commercial electrowinning in aqueous solutions often involves acid. The hydrogen ions in the acid as well as the counter ions (usually sulfate) provide most of the solution conductivity. The rate of electrowinning is determined by electrochemical kinetics as discussed in Chap. 4. The process of electrowinning is depicted in Fig. 7.2.
