    2014-5-8 · Loss in metal production is typical for all electrolytic processes and is, therefore, very difficult to avoid completely. The principal loss mechanism in aluminum electrolysis is recombination of the anodic and cathodic products, the so-called “back reaction,” where aluminum back-reacts with CO 2 to form alumina and carbon monoxide.
