Aluminum Smelting | HowStuffWorks

How Aluminum Works. The steps in aluminum smelting are described below: Alumina is dissolved in molten cryolite at 1,000 degrees C (1,832 degrees F). This may seem like an extraordinarily high temperature until you realize that the melting point of pure alumina is 2,054 degrees C (3,729 degrees F).
