Bauxite — Wikipedia Republished // WIKI 2

The first step in producing aluminium is mining its ore – bauxite.Bauxite is the primary ore from which aluminium metal is extracted.Australia has the second largest reserves of bauxite in the world and is currently the leading producer with five mines supplying around 23 per cent of global production.

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.
