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.

The most prevalent usage for activated alumina is as a desiccant. In this application, water contained in air sticks to the alumina surface as the air passes through the alumina pores. The water molecules become trapped and are filtered from the air. This process is reversible by heating the alumina to 390Â°F (200Â°C).
