Abstract
A method for producing metal by electrolysis in a molten salt bath containing superimposed electrodes, at least one of which is a bipolar electrode. The arrangement of the electrodes creates interelectrode spaces between them. Bath is swept through these interelectrode spaces. This method is improved by providing circulation of the bath from one interelectrode space to the next at a location inwards of the outer peripheries of the electrodes. This can be accomplished e.g. by boring holes through the electrodes. It can also be accomplished by breaking the electrodes into individual, mutually separated stacks of electrodes, the circulation of the improvement then occurring e.g. in the space between the stacks.
