Bauxite ore is the main source of aluminum and contains the aluminum minerals gibbsite, boehmite, and diaspore. Aluminum is used in the United States in packaging, transportation, and building. Because it is a mixture of minerals, bauxite itself is a rock, not a mineral. Bauxite is reddish-brown, white, tan, and tan-yellow.
Bauxite often coexists with iron oxides and hydroxides, anatase, kaolinite, chlorite and other clay minerals. Sometimes it also contains calcium, magnesium, sulfur and other minerals. Bauxite ore can be divided into high alkali bauxite, high titanium bauxite and high iron bauxite according to the impurities contained therein.
