  • Method and apparatus for the electrolytic extraction of metals from a solution containing metal ions
    Patent number: 5372683
    Abstract: For the electrolytic extraction of metal from a solution containing metal ions and situated in a first cell, metal is cathodically deposited by means of an anode on an electrically conductive endless band immersed partially into the solution, and is redissolved anodically in the electrolyte of an adjacent second cell by partial immersion of the circulating endless band; the metal dissolved in the second cell is again deposited in high purity on a cathode.
    Type: Grant
    Filed: November 25, 1991
    Date of Patent: December 13, 1994
    Assignee: W. C. Heraeus GmbH
    Inventors: Jochen-Werner Kuhn-von Burgsdorff, Ulrich Stroder
  • Method for obtaining neodymium or neodymium-iron alloy by electrolysis of melts containing neodymium compounds
    Patent number: 5346608
    Abstract: Neodymium and neodymium-iron alloys are obtained by electrolysis of a neodymium salt melt using magnetite as the anode material. The cathode is non-consumable or is made of iron to be consumed and form a neodymium-iron alloy. The electrolysis is preferably carried out under a protective atmosphere.

    Assignees: Heraeus Elektrochemie GmbH, Moltech Invent SA
    Inventors: Ulrich Stroder, Jean-Jacques Duruz, Jean-Louis Jorda
  • Laminated electrode the use thereof
    Patent number: 4765874
    Abstract: Laminated electrodes and a method for their preparation are described, these electrodes being composed of electrically conductive plastic having catalytic particles, composed of a catalyst deposited on supporting particles, pressed partially into the plastic. They can be used as oxygen anodes, for example in the electrolytic recovery of metal from aqueous solutions.
