Theoretical Production of Aluminum

Let’s consider the alumina reduction reaction:

Aluminum Reduction Reaction

This reaction involves the flow of 6 moles of electrons from the cathode to the anode to produce 2 moles of aluminum.

This means that, to produce 2 moles of aluminum atoms, which weight:

Aluminum Atomic Weight

are involved 6 moles of electrons, hence 6 Faradays of electrical charge:

Coulomb Faraday

Combining the (1) and (2) for each Coulomb of electrical charge flown into the electrolyte are produced:

Aluminum Coulomb

So, in 24 hours a cell with a line current of I amperes produces:

kilograms aluminum per day
