  • How aluminium is produced

    The next stage in the production chain is the processing of bauxite into alumina, or aluminium oxide Al 2 O 3, a white powder. The most common process for making alumina from bauxite is the Bayer process, which was first discovered over 100 years ago but is still in wide use today. About 90% of alumina refineries in the world use the Bayer process. It's very efficient but it can only be ...
