Abstract
An electrolytic reduction cell for the production of metal is provided, in which liquid metal is deposited at or adjacent an upper surface of a cathode. The electrolytic reduction cell includes an anode structure and a cathode located beneath the anode structure, wherein an upper portion of the cathode comprises an aggregate of particles sized and shaped such that in operation of the cell liquid metal is present in at least an upper part of the aggregate and a slurry of liquid metal and particles is established, the slurry comprising a substantially uniform dispersion of the particles in a continuous liquid phase of the liquid metal, the slurry having a viscosity sufficiently high such that under operating conditions of the cell the slurry is relatively immobile. Methods for the production of a metal by electrolysis in the electrolytic cell are also provided.
