aluminum processing, preparation of the ore for use in various products.. Aluminum, or aluminium (Al), is a silvery white metal with a melting point of 660 °C (1,220 °F) and a density of 2.7 grams per cubic cm. The most abundant metallic element, it constitutes 8.1 percent of Earth's crust. In nature it occurs chemically combined with oxygen and other elements.

Although aluminum is the most abundant metal in the earth's crust, it is never found free in nature.All of the earth's aluminum has combined with other elements to form compounds. Two of the most common compounds are alum, such as potassium aluminum sulfate (KAl(SO 4) 2 ·12H 2 O), and aluminum oxide (Al 2 O 3).About 8.2% of the earth's crust is composed of aluminum.

Aluminum is a reactive metal and it is hard to extract it from its ore, aluminum oxide (Al 2 O 3). Aluminum is among the most difficult metals on earth to refine, the reason is that aluminum is oxidized very rapidly and that its oxide is an extremely stable compound that, unlike rust on iron, does not flake off.
