Abstract

The cathodic reduction of natural samples of high-purity galena has been studied in both acidic and alkaline solutions. The products of the reaction are lead metal and, depending on the pH value, the various forms of sulphide ion. Linear-sweep voltammetric measurements in solutions of various pH values have been used to obtain current-potential data from which possible mechanisms for the reaction have been derived. Results are also presented that show that the cathodic reduction of anodically produced sulphur is possible, but that the rate of reduction is strongly dependent upon the amount of sulphur present and its history.
