Abstract

Abstract Electrodissolution processes in hydrometallurgy have been reviewed in this report. While a considerable amount of basic definitive studies and laboratory scale development work has been carried out, particularly on metal and mineral sulphide slurries, commercial application of electro-dissolution has been restricted to electrorefining of metals and to cast matte anode electrolysis of nickel. It is concluded that considerable scope exists for the development of electrodissolution processes for slurries of mineral sulphides provided that satisfactory potential control can be achieved in the slurry. Electrooxidation processes producing the oxidant in a water soluble form may be the simplest way of obtaining potential control in these systems. This work was supported by the Chemicals and Minerals Requirements Board (Department of Industry).
