Aluminium visually resembles silver, both in its color and in its great ability to reflect light. It is soft, non-magnetic and ductile. It has one stable isotope, 27 Al; this isotope is very common, making aluminium the twelfth most common element in the Universe. The radioactivity of 26 Al is used in radiodating .

Aluminum Manufacturing Industry Description and Practices The production of aluminum begins with the mining and beneficiation of bauxite. At the mine (most of which are of the surface type) bauxite ore is removed to a crusher following which the crushed ore is screened and stockpiled ready for delivery to an alumina plant.

ALUMINA PRODUCTION. Bauxite is crushed, dried and ground in special mills where it is mixed with a small amount of water. This process produces a thick paste that is collected in special containers and heated with steam to remove most of the silicon present in bauxites. The ore is loaded into autoclaves and treated with lime–caustic soda.

The aluminium production process can be broken down into three stages; first bauxites, which contain aluminium, are extracted from the ground. Second, bauxites are processed into alumina or aluminium oxide, and finally in stage three, pure aluminium is produced using electrolytic reduction, a process in which aluminium oxide is broken down into its components using electric current.

Production. Aluminum does not exist in a pure state in nature. The production of primary aluminum metal begins with bauxite ore, which is composed of hydrated aluminum oxide (40% to 60%) mixed with silica and iron oxide. It takes approximately 4 to 5 tonnes of bauxite ore to produce 2 tonnes of alumina.
