Abstract: There is provided a method of charging an electrolyte bath containing aluminum oxide for the manufacture of aluminum by smelt electrolysis, with fresh supplies of aluminum oxide as the electrolyte is depleted thereof. A pre-determined store of aluminum oxide is constantly maintained on the crust covering the bath. This crust is then partially broken by raising and lowering the anode at predetermined intervals during the electrolysis to permit the oxide resting on the crust to enter the bath, thereby to increase the aluminium oxide content of said bath.
