Bauxite geology.arkansas.gov

In the bauxite refining process, the aluminum bearing minerals in bauxite are converted in a multiple step process to alumina (Al2O3). Alumina can be smelted to form metallic aluminum or it can be used as the source of many other products, including refractory materials used to line high temperature rotary kilns and metallurgical furnaces.

Bauxite mining in the United States

Bauxite forms by the weathering of aluminum rich and silica poor rocks in hot, humid, climates, at places with good drainage. Under the proper conditions, weathering disintegrates the aluminium silicate minerals, and dissolves and removes the silica, creating bauxite. The mined US bauxite deposits have all been in the southeastern United States.
