| 摘要 |
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 aluminiu m by use of essentially inert electrodes in a vertical and/or inclined positio n, where said cell design facilitates separation of aluminium and evolved oxyge n gas by providing a gas separation chamber (14) arranged in communication wit h the electrolysis chamber (22), thus establishing an electrolyte flow between the electrolysis chamber (22) and the gas separation chamber (14).
