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.

Aluminium
Aluminium can be extracted (uneconomically) from some clays but the most common aluminium ore is a material called bauxite. First the aluminium ore needs to be mined, then the bauxite is refined into alumina (aluminium oxide). Large amounts of electricity are used to smelt the alumina into aluminium metal.
