Abstract
An exchangeable separator is horizontally located within a three-layer refining cell for the electrolytic purification of aluminum. This separator is freely movable in the vertical direction within a movement space (h) defined by a refractory frame. The porosity of the separator is at least 30%, preferably at least 50%, so that the electrolyte and metal can pass through the separator without any significant additional loss of potential. In industrial refining cells, the separator appropriately has a thickness of 0.5 to 2 cm and a disc-shaped design, the vertical movement space (h) being 0.5 to 1 cm. The level changes produced during the operation of the cell can be compensated for in this free movement space.
