How aluminium is produced
Second, bauxites are processed into alumina or aluminium oxide, and finally in stage three, pure aluminium is produced using electrolytic reduction, a process in which aluminium oxide is broken down into its components using electric current. About 4-5 tonnes of bauxites get processed into 2 tonnes of alumina from which about 1 tonne of aluminium can be made.

High Purity Alumina stocks on the ASX: The .
Traditionally high purity alumina is produced from aluminium metal; however, new technologies have produced it from aluminous clay (kaolin). "If you think about where aluminium metal comes from – it comes from the bauxite process where they've already made an alumina. But, they can't use it because there is so much sodium locked into the crystal structure. HPA producers have to use the ...
