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. free form state is referred to as the mineral corundum. In

Aluminum Smelting HowStuffWorks

­Transforming alumina aluminum oxide into aluminum represented a major milestone in the industrial revolution. Until modern smelting techniques evolved, only small quantities of aluminum could be obtained. Most ea­rly processes relied on displacing aluminum with more reactive metals, but the metal remained expensive and relatively elusive.
