Aluminium Smelting | The Australian Aluminium Council
Anodes are used to conduct electricity into the smelting cells/pots in the pot room. Anodes are consumed in the smelting process and the remaining portions (known as butts) are recycled. Anode Bake. Anodes are attached to rods and suspended into the electrolytic cells in the pot room where they are slowly consumed in the aluminium smelting process.
