Bauxite, the principal ore used for aluminum smelting, is named after Les Baux, Provence, the village where the first deposits were discovered. Bauxite contains hydrated alumina equivalent to as much as 40–60% Al 2 O 3, and is free of the other siliceous materials leached out over time. However it still contains 10–30% iron oxide, and some silica and other impurities, making it unsuitable for direct .
