Abstract (en)

[origin: EP1785509A1] A process for production of a metal includes a step of filling a metal chloride in an electrolysis vessel having positive and negative electrodes, a step of heating and fusing the metal chloride to make an electrolytic bath, and a step of electrolyzing the electrolytic bath to deposit metal on the negative electrode in a solid state. In addition, in an apparatus for production of a metal in which a metal chloride is filled in an electrolysis vessel having positive and negative electrodes, the metal chloride is heated and molten to make an electrolytic bath and the electrolytic bath is electrolyzed to deposit the metal on the negative electrode in a solid state, the electrolytic bath is divided into an electrolysis chamber and a dissolution chamber by a dividing wall, the positive electrode is arranged in the electrolysis chamber, the negative electrode is arranged to enable orbital movement in a circle through the electrolysis chamber and dissolution chamber, and the metal deposited on the negative electrode in the electrolysis chamber is separated and recovered in the dissolution chamber.
