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.Get A Quote

History of the Bayer Process Bayer process was invented by Austrian chemist, Carl Josef Bayer in 1887, while working in Saint Petersburg, Russia for developing a method to supply alumina to the textile industry. The Bayer process started gaining importance after the invention of Hall-Heroult aluminium process.
Anodes are used to conduct electricity into the smelting cellspots in the pot room. Anodes are consumed in the smelting process and the remaining portions known as butts are recycled. Anode Bake. Anodes are attached to rods and suspended into the electrolytic cells in the pot room where they are slowly consumed in the aluminium smelting process.
