Aluminium production cell and assembly

In a cell for the production of aluminium by the electrolysis or a molten electrolyte, in particular the electrolysis of alumina dissolved in a fluoride-based molten cleatrolyte, comprising a plurality of anodes immersed in the molten electrolyte above a cell bottom whereon molten product aluminum is collected in a pool containing at least one body of aluminium-resistant material, the improvement wherein

• the anodes are as related with said at least one body formed by a grid assembly of side-by-side upright or inclined walls made of or coated with aluminium-resistant material, each said body being dimensioned to allow sludge and molten electrolyte to pass through to the cell bottom, the walls of said body. having top and bottom ends, said top ends being placed under the anode and said bottom ends standing on the cell bottom covered by the pool of molten aluminium, the bottom ends forming a base which is larger than the height of the walls, each said body being easily insertable onto the cell bottom, being easily removable from the cell and each said body being adapted to remain stable on the cell bottom during operation of the cell.
