The starting material for electrolytic smelting of aluminum is pure, anhydrous alumi-num oxide (Al 2 O 3) called alumina. In the Western World, the Bayer 1 process, invented in the 19th century, is by far the most important process used in the production of alumi-num oxide from bauxite. The process has been refined and improved since its inception.

Alum can be created through one of several chemical processes. One is by adding aluminum hydroxide Al(OH)3 to sulfuric acid H2SO4. The chemical reaction is: 2 Al(OH)3 + 3 H2SO4 → Al2(SO4)3 + 6H2O Translated to plain english, adding 2 molecules of aluminum hydroxide to 3 molecules of sulfuric acid results in 1 mole…
