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 ...

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.
How Aluminum Works. Then workers loosen the soil with explosives, which bring the ore to the surface. Giant shovels then scoop up the bauxiterich soil and dump it into trucks, which carry the ore to a processing plant. France was the first site of largescale bauxite mining. In the United States, Arkansas was a major supplier of bauxite before,...
