Bauxite is the major alumina (Al 2 O 3 ) bearing ore used in the aluminum manufacturing industries. The bauxite containing less than 50% Al 2 O 3 is called low-grade bauxite ore which is commonly used for the alumina -based abrasives and refractories productions.

Bauxite (Fig. 1.33) is formed by surface weathering of clay rocks around the tropical region and composer of aluminum oxide (Al(OH) 3).It contains 15%–25% aluminum and only ore used for commercial extraction for aluminum. The bauxite occurs as near-surface layers and usually mixed with clay minerals, iron oxide, and titanium dioxide.
