A cell for the electrowinning of aluminium has a cell bottom that comprises: a series of carbon cathode blocks (25) having an aluminium-wettable upper surface (22); aluminium-wettable openly porous plates (21) which are placed on the upper surfaces (22) of the carbon cathode blocks (25) and which are filled with molten aluminium to form an aluminium-wetted drained active cathode surface (20) above the upper surfaces (22) of the carbon cathode blocks (25); and a recess (35) formed in a reservoir body 30 and located at a level below the upper surfaces (22) of the carbon cathode blocks (25) and which during use collects molten aluminium (60) drained from the aluminium-wettable drained active cathode surface (20). Openly porous plates (21) on the upper surfaces (22) of the carbon cathode blocks (25) extend over at least part of the recess (35) such that part of the aluminium-wetted drained active cathode surface (20) is located over the aluminium collection recess (35).

L'invention concerne une enceinte d'électro-extraction d'aluminium. Cette enceinte comprend une série de blocs (25) cathodiques à base de carbone présentant une surface (22) supérieure mouillable à l'aluminium, des plaques (21) à pores ouverts mouillables à l'aluminium qui sont installées sur les surfaces (22) supérieures des blocs (25) cathodiques de carbone et sont remplies d'aluminium fondu de manière à constituer une surface (20) cathodique active drainée, mouillée à l'aluminium, au dessus des surfaces (22) supérieures des blocs (25) cathodiques de carbone, et un évidement (35) formé dans un corps (30) de réservoir et placé à un niveau situé en dessous des surfaces (22) supérieures des blocs (25) cathodiques de carbone et qui, lorsque l'enceinte est opérationnelle, collecte l'aluminium drainé à partir de la surface (20) cathodique active drainée mouillable à l'aluminium. Les plaques (21) à pores ouverts installées sur les surfaces (22) supérieures des blocs (25) cathodiques de carbone recouvrent au moins une partie de l'évidement (35), de sorte qu'une partie de la surface (20) cathodique active drainée mouillée à l'aluminium est placée au dessus de l'évidement (35) de collecte d'aluminium.
