Abstract (en)
[origin: ES8602967A1] Electrolytic winning of metal from a bath contg. the metal halides is carried out by passing a first current I, between a central anode and a surrounding cathode shaped in the form of a basket until the basket is 1/3-2/3 full of deposited metal and at the same time a second current I, is passed between the basket and an auxillary cathode(s) placed outside the basket to deposit metal on the cathode. The halide is regularly fed into the bath between anode and basket and basket and auxiliary cathode. The amt. of metal is 1-7 wt.%. The auxiliary cathode is periodically extracted and replaced with another.

Abstract (fr)
L'invention concerne un procédé et une cellule d'électrolyse pour l'obtention d'un métal par électrolyse d'halogénures en bain de sels fondus. Elle consiste à utiliser une cathode en forme de panier (14), à faire passer simultanément un courant I1 entre cette cathode et l'anode (10) de manière à effectuer un premier dépôt de métal brut dans la panier et un courant I2 entre ledit panier et des cathodes complémentaires (29, 23) pour déposer sur celleci le métal final. La cellule comprend un ensemble anodique central (10), un panier cathodique tubulaire (14) entourant l'anode et une série de cathodes (29, 23) entourant ce panier, disposition qui peut être inversée par rapport au panier. L'invention trouve son application dans la fabrication en continu d'un métal réfractaire de bonne qualité avec un rendement matière et électrique convenable.
