<p>The present invention describes a process for the electrolytic recovery of a metal, such as copper, from a single halide solution, wherein the single halide solution includes a variable valence ion, such as managanese, which does not contaminate the cathodically recovered metal. The ratio of the halide to the variable valence ion is controlled such that the solution can reach an Eh close to but less than that at which evolution of halogen gas occurs. The electrolyte recovered from this process may be used subsequently for the electrochemical leaching of metals, such as gold.</p> |
