May 25, 2017· Description Bauxite refers to the materials with the main ore of gibbsite, bodhmite, and diaspore. The application field of it has metal and nonmetal. Bauxite is the best material in making aluminum and the ingredient of refractory, grinding mater...
Aluminum is the most abundant metal in the earth’s crust and is a constituent of many minerals. However, the material which is highest in aluminum and most free from objectionable impurities is bauxite which, therefore, is practically the only source of the metal under present processes. Bauxite is the general name given to the hydrated oxides of aluminum.
Bauxite is primarily comprised of aluminum oxide compounds (alumina), silica, iron oxides and titanium dioxide. Approximately 70 percent of the world’s bauxite production is refined through the Bayer chemical process into alumina. Alumina is then refined into pure aluminum metal through the Hall–Héroult electrolytic process. Mining bauxite

Bauxite is the main source of the rare metal gallium. During the processing of bauxite to alumina in the Bayer process, gallium accumulates in the sodium hydroxide liquor. From this it can be extracted by a variety of methods. The most recent is the use of ion-exchange resin.
Bauxite deposition takes place more within tropical areas where temperature and rainfall are high. Bauxite reserves of Debrecen in Hungary, Ural in Russia, Arkansas and Georgia in U.S.A. suggest that during past geological periods it certainly had gone through warm and wet climate.
