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.
The stage of cathodic dissolution of the halide is carried out separately from the extraction stage with the use of composite electrode similar to that used in the extraction stage.
