Bauxite Geoscience Australia

Bauxite is a heterogeneous, naturally occurring material of varying composition that is relatively rich in aluminium. The principal minerals in bauxite are gibbsite (Al 2 O 3.3H 2 O), boehmite (Al 2 O 3.H 2 O) and diaspore, which has the same composition as boehmite, but is denser and harder. Australia is the world's largest producer of bauxite

Bauxite mining in the United States Wikipedia

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.
