Aluminum smelting pot-cell

摘要: The aluminum smelting from alumina in the Hall-Heroult cells can be dramatically improved by using one or a combination of following features together alternative to Bayer as feedstock: Al +++ alumina, sawtooth shaped electrodes, and lower temperatures. Laboratory experiments have shown that higher rates dissolution molten fluoride baths combined with voltage drops design electrodes allow operation at even current density, thus increasing overall productivity efficiency cells.
