Alumina Refining | The Aluminum Association

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.
