Bauxite is a sedimentary rock composed mainly of aluminum-bearing minerals. It is the primary ore from which aluminum is extracted economically.
It typically consists of various aluminum hydroxide minerals, along with iron oxides, silica, and other impurities. It ranges in color from reddish-brown to white, depending on the iron content and other mineral impurities. Bauxite forms through weathering and leaching of aluminum-rich rocks in tropical and subtropical regions, often under high rainfall conditions.
