Abstract

A cell for the electrowinning of aluminium comprises a horizontal carbon cathode bottom (11) having an aluminium-wettable surface coating (25) and a series of plates (21) made of aluminium-wettable reticulated porous material, typically foams, filled with aluminium and placed flat on the aluminium-wettable surface coating (25). During use, a thin bottom layer of aluminium (22) wets the aluminium-wettable surface coating (25) on top of the cathode bottom (11) and a bottom part of the porous aluminium-filled plates (21). A top layer of aluminium (23) is formed above the porous aluminium-filled plates (21). The cell may be operated with metal anodes (10) possibly protected with a cerium oxyfluoride coating when operated above about 910°-930° C.
