Patent number: 6911135Abstract: A method for separating a metal from a composition including the metal involves forming an electrolytic cell in which the anode comprises a composition including the metal. The electrolyte is an ionic liquid. A sufficient potential difference is applied between the anode and the cathode to cause the metal to transfer from the anode to the cathode deposited thereon.Type: GrantFiled: August 18, 2000Date of Patent: June 28, 2005Assignee: British Nuclear Fuels PLCInventors: Robert Charles Thied, Justine Elizabeth Hatter, Kenneth Richard Seddon, William Robert Pitner, David William Rooney, David Hebditch

Patent number: 6468495Abstract: A method of removing from a metal salt ionic species contained therein involves contacting the metal salt with an ionic liquid to dissolve the metal salt, the ionic species or both. At least in the case where both the metal salt and the ionic species are dissolved, the resultant ionic liquid composition is treated to separate the ionic species therefrom and subsequently processed to recover the metal salt.Type: GrantFiled: October 20, 2000Date of Patent: October 22, 2002Assignee: British Nuclear Fuels PLCInventors: Mark Fields, Robert Charles Thied, Kenneth Richard Seddon, William Robert Pitner, David William Rooney
