Abstract

See full text

A method and ionic liquid for the electrorecovery of metal from a metal salt including at least one metal ion. The method includes the steps of dissolving the metal salt in an ionic liquid, the ionic liquid including an ionic liquid cation and an ionic liquid anion; whereby the metal ion of the metal salt forms a metal complex in solution with at least the ionic liquid cation; and subjecting the metal complex to an electrical potential between a cathode and anode to recover metal at the cathode. The ionic liquid includes an ionic liquid cation and an ionic liquid anion, wherein the ionic liquid cation has an affinity for the metal ion which is at least about equal to that of the ionic liquid anion for the metal ion.
