金属を生成する方法及び電解採取槽
Document Type and Number:
Japanese Patent JP2004526055
Kind Code:
A
Abstract:
The present invention relates to a method for production of molten aluminium by electrolysis of an aluminous ore, preferably alumina, in a molten salt mixture, preferably a sodium fluoride-aluminium fluoride-based electrolyte. The invention describes an electrolysis cell for said production of aluminium by use of essentially inert electrodes in a vertical an/or inclined position, where said cell design facilitates separation of aluminium and evolved oxygen gas by providing a gas separation chamber ( 14 ) arranged in communication with the electrolysis chamber ( 22 ), thus establishing an electrolyte flow between the electrolysis chamber ( 22 ) and the gas separation chamber ( 14 ).
