Abstract

An aluminium smelting cell comprising a floor defining a cathode surface (4) which is substantially horizontal in the longitudinal direction of an overlying anode (1), shaped structures (2,3) projecting from the cathode surface (4) and having exposed surfaces of aluminium wetted material, the shaped structures being positioned to cause preferential contouring of the anode (1), particularly at its longitudinal edges (5,6) to allow for improved bubble release and to minimize cell resistivity.
