The process is carried out in a long series of electrolytic cells carrying direct current. The alumina is dissolved in a molten bath of cryolite (an electrolyte) and aluminum fluoride (which increases the conductivity of the electrolyte). These chemicals are assumed to be recovered with little or no loss, and therefore negligible inputs of these materials are assumed for this LCI. Carbon anodes carry the current to the solution, and on to the next cell. The anodes are consumed during the reaction at a rate of approximately 500 kg of material per 1,000 kg of aluminum produced. The principal products of the reaction are carbon dioxide, which is released as a gas, and elemental aluminum, which settles to the bottom of the cell and is periodically drained off.Important note: although most of the data in the US LCI database has undergone some sort of review, the database as a whole has not yet undergone a formal validation process.
