Title:
METHOD AND APPARATUS FOR PRODUCING METAL BY ELECTROLYSIS OF MOLTEN SALT
Document Type and Number:
WIPO Patent Application WO/2006/003864
Kind Code:
A1
Abstract:
A method for producing a metal, which comprises filling an electrolytic vessel having an anode and a cathode with a metal chloride, heating the metal chloride into a melt, to form an electrolytic bath, and subjecting the electrolytic bath to electrolysis, to thereby precipitate the metal on the cathode; and an apparatus for producing a metal by the electrolysis of a molten salt wherein an electrolytic vessel having an anode and a cathode is filled with a metal chloride, the metal chloride is heated into a melt to form an electrolytic bath, and the electrolytic bath is subjected to electrolysis, to thereby precipitate a metal in a solid state on the cathode, which comprises dividing the electrolytic bath by a partition into an electrolysis chamber and a dissolution chamber, placing an anode in the electrolysis chamber and arranging the cathode in such a manner that it can be circulated and revolved between the electrolysis chamber and the dissolution chamber, to thereby precipitate the metal on the cathode in the electrolysis chamber and release and recover the metal in the dissolution chamber.
