  • Patent number: 5015342
    Abstract: In a method for the production of a polyvalent metal, particularly titanium, by the cathodic dissolution of a halide of the metal in an electrolyte of alkali or alaline earth metal halides and the electro-extraction of the dissolved metal ions, the electro-extraction stage is carried out with the use of a composite electrode including an anode and a framework surrounding the anode and provided with metal partitions capable of anodic dissolution for confining within the framework a bath of alkali or alkaline earth metal halides which does not contain ions of the metal to be produced, and then applying a potential between the anode and the framework to cause the formation of an accumulation of alkali metal or alkaline earth metal by cathodic reduction, after which a potential is applied between the anode and the cathode to cause the deposition of the metal to be produced at the cathode and the simultaneous anodic dissolution of the partitions.
