Abstract

Une methode d'extraction electrolytique de gallium ou de gallium avec un concentre de vanadium a partir de solutions alcalines de production d'alumine consiste a effectuer l'electrolyse sur des electrodes solides avec un courant cathodique de 3,4 a 4,5 V a une temperature de 28 a 37 C et en presence d'un metal qui est introduit d'abord dans les solutions initiales en exces dans des proportions de 1 a 10 par rapport au gallium et qui, lorsqu'il est soumis avec le gallium a la reduction electrolytique, forme un alliage non susceptible de passivation dans les conditions de l'electrolyse.
