How Aluminum is Produced

The key to the chemical reaction necessary to convert the alumina to metallic aluminum is the running of an electrical current through the cryolite/alumina mixture. The process requires the use of direct current (DC) not the alternating current (AC) used in homes. The immense amounts of power required to produce aluminum is the reason why
