Alumina Refining The Aluminum Association

Alumina is the common name given to aluminum oxide (Al 2 O 3). Alumina is produced from bauxite, an ore that is mined from topsoil in various tropical and subtropical regions. The Bayer process, discovered in 1887, is the primary process by which alumina is extracted from bauxite. To produce pure aluminum, alumina is smelted using the Hall
