Flow Chart Of Hall Heroult Process

2019-6-21Hall-Heroult Cell for the Production of Aluminium Key Concepts. Pure alumina, Al 2 O 3, is extracted from the mineral bauxite using hot concentrated sodium hydroxide solution in the Bayer Process. Amphoteric alumina dissolves in the sodium hydroxide while other substances present such as iron oxides and silicates do not dissolve.
