Bauxite - an overview | ScienceDirect Topics

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.
