The first step in producing aluminium is mining its ore – occurs mainly in tropical and subtropical areas, like Africa, the West Indies, South America and Australia – there are some small deposits located in Europe. Australia is the largest producer of bauxite, with five mines supplying around 23 per cent of global production.

The Bayer process is the principal industrial means of refining bauxite to produce alumina (aluminium oxide) and was developed by Carl Josef Bayer. Bauxite, the most important ore of aluminium, contains only 30–60% aluminium oxide (Al 2 O 3), the rest being a mixture of silica, various iron oxides, and titanium dioxide.
