Title
(EN) METHOD, APPARATUS AND MEANS FOR PRODUCTION OF METALS IN A MOLTEN SALT ELECTROLYTE
(FR) PROCÉDÉ ET APPAREIL DE PRODUCTION DE Ti DANS UN ÉLECTROLYTE À SEL FONDU
Abstract
(EN)
This invention describes a method of producing a metal, M1, in an electrolytic cell consisting of a molten electrolyte, MzY - MzO, at least one anode and at least one cathode, characterised in that the passage of current between said anode(s) and cathode(s) through said electrolyte, produces a metal, M1, from a raw material, M1X, containing a non-metallic species, X, under conditions such that the potential at the cathode causes the reduction of the Mz cation and the formation of M2 at activities less than one, and the potential at the cathode is insufficient to cause formation of Mz metal as a discrete solid or liquid phase, and the Mz so produced reduces the raw material, M1X, at the cathode, to M1.
(FR)
La présente invention concerne un procédé de production d'un métal, M1, dans une cellule électrolytique consistant en un électrolyte fondu, MzY - MzO, au moins une anode et au moins une cathode, caractérisé par le fait que le passage du courant entre ladite ou lesdites anodes et ladite ou lesdites cathodes à travers ledit électrolyte produit un métal, M1, à partir d'une matière brute, M1X, contenant une espèce non métallique, X, dans des conditions telles que le potentiel à la cathode provoque la réduction du cation Mz et la formation de M2 à des activités inférieures à un et que le potentiel à la cathode est insuffisant pour provoquer la formation du métal Mz en tant que phase liquide ou solide discrète, et le Mz ainsi produit réduit la matière brute, M1X, au niveau de la cathode, en M1.
