The principal ore of aluminum is bauxite, a complex mixture of a number of aluminum hydroxides and hydrous aluminum oxides. The most common aluminumbearing minerals in bauxite are gibbsite (AlOH3), boehmite (AlO(OH)), and diaspore (AlO(OH)). In the Arkansas deposits, diaspore has not been reported.
10 Uses for Chalk. Here are some tips for multitasking with the powdery staple. 1. File Right. Rubbing chalk onto a metal file makes its teeth easier to clean by reducing their tendency to clog with soft metals. 2. Degrease a Collar. Rub the spot with white chalk, let it sit, then dust it off.
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 .
