摘要
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).
