Alumina Refining The Aluminum Association

Alumina Refining. Quick Read. 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–Héroult electrolytic ...

Alumina Refining The Aluminum Association

Alumina is properly called aluminum oxide, which is a chemical compound comprised of aluminum and oxygen molecules (Al 2 O 3). When refined from bauxite, alumina generally looks like a white powder similar to table salt or granular sugar. Aluminum oxide is typically referred to as alumina, but may also be called aloxide, aloxite or alundum, depending on the industry and the metal’s use.
