Bauxite is a soft limonite iron ore rock with portions of its iron composition replaced by aluminum. Bauxite forms when silica leaches out from laterite soil. Bauxite does not exhibit any particular composition instead it is just an assortment of clay minerals, aluminum hydroxides, and hydrous aluminum oxides.
Bauxite. Bauxite is the most important ore of aluminum which contains only 30–54% alumina, Al2O3; the rest is a mixture of silica, various iron oxides, and titanium dioxide along with trace amounts of zinc, phosphorous, nickel, vanadium etc., as indicated earlier.
The separation of the alumina from the impurities in the bauxite ore is usually accomplished by the Bayer Process. In this process the ground bauxite is leached with caustic soda (NaOH) to produce soluble sodium aluminate (NaAlO2), leaving the impurities in the insoluble residue.
