Title (EN) ELECTROLYTIC PRODUCTION OF REACTIVE METALS
(FR) PRODUCTION ÉLECTROLYTIQUE DE MÉTAUX RÉACTIFS
Abstract:
(EN) A method of and system for electrolytic production of reactive metals is presented. The method includes providing a molten oxide electrolytic cell including a container, an anode, and a current collector and disposing a molten oxide electrolyte within the container and in ion conducting contact with the anode and the current collector. The electrolyte includes a mixture of at least one alkaline earth oxide and at least one rare earth oxide. The method also includes providing a metal oxide feedstock including at least one target metal species into the molten oxide electrolyte and applying a current between the anode and the current collector, thereby reducing the target metal species to form at least one molten target metal in the container.
(FR) La présente invention concerne un procédé et un système de production électrolytique de métaux réactifs. Le procédé comprend la fourniture d’une cellule électrolytique d’oxyde fondu comprenant un récipient, une anode et un collecteur de courant et la disposition d’un électrolyte d’oxyde fondu à l’intérieur du récipient et en contact conducteur d’ions avec l’anode et le collecteur de courant. L’électrolyte comprend un mélange d’au moins un oxyde de métal alcalino-terreux et d’au moins un oxyde de terre rare. Le procédé comprend en outre la fourniture d’une matière première d’oxyde métallique comprenant au moins une espèce métallique cible dans l’électrolyte d’oxyde fondu et l’application d’un courant entre l’anode et le collecteur de courant, de façon à réduire l’espèce métallique cible pour former au moins un métal cible fondu dans le récipient.
