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 ...

To review, alumina starts as bauxite that is mined from the ground and then heated with various chemicals and purified to alumina. The yield from bauxite to Al2O3 is roughly 2:1. This powdered Al2O3 is further purified to aluminum, with another yield of roughly 2:1, so each pound of aluminum metal starts with 4 pounds of bauxite.
