FIELD: metallurgy.
SUBSTANCE: invention relates to a method for the purification of aluminum. Method includes supplying aluminum raw materials to the electrolyzer through the access channel to the electrolyzer, directing the electric current in the anode through the electrolyte and to the cathode, the anode is made elongated vertical, the cathode is made elongated vertical, the anode and cathode are made to pass into the electrolyte zone, so that inside the electrolyte zone the anode and cathode are placed with an anode-cathode overlap and anode-cathode distance; and obtaining some purified aluminum product from aluminum raw materials.
EFFECT: reduced energy consumption and increased productivity.
