Abstract

L'invention concerne un procédé pour produire un métal, un métalloïde ou un alliage à partir d'un oxyde métallique, d'un oxyde de métalloïde ou d'un mélange d'oxydes d'éléments d'alliages formant une électrode de travail, par électrolyse dans un sel fusionné ou un mélange de sel en présence d'une contre-électrode. Ledit procédé comprend l'application d'une pluralité de cycles d'électrolyse sur une électrode de travail, au moins une partie du cycle d'électrolyse est effectuée sur un potentiel cathodique par rapport à la contre-électrode dans des conditions permettant d'éliminer l'oxygène du métal, du métalloïde ou de l'oxyde mélangé ; au moins une autre partie du cycle de l'électrolyse est effectué à une tension anodique par rapport à la contre-électrode, de sorte que l'ionisation des impuretés métalliques de l'oxyde soit effectuée au lieu de l'élimination de l'oxygène et lesdites impuretés sont éliminées dans l'électrolyte.
