Aluminum is the third most abundant in Earth's crust after oxygen and silicon element and represents 7.3% of its mass.
Aluminum began to be produced commercially in the second half of the nineteenth century by which it can be still considered a young material, in comparative terms, considering that mankind has used copper, lead and tin for thousands of years. However, the production of aluminum today amount exceeds the sum of the remaining non-ferrous metals such as copper, lead and tin.
Aluminum is the metal whose consumption evolves more rapidly, which is due to the multiplicity and importance of its applications and its great ability to substitute other metals advantages. So much so that according to statistics, global consumption is doubling every ten years or less, since it grows at 10% annually.
· Bauxite: natural mineral containing aluminum, oxygen and hydrogen. It is the main source for the production of alumina. Most of the world production of bauxite-about 85% - is used as Insuma in alumina production. Alumina: It is a synthetic aluminum oxide derived from bauxite. Over 90% of the world production of alumina is used as a raw material for casting primary aluminum metal.
· Primary Aluminum: Aluminum is the metal as an end product which is obtained from alumina. The "primary" designation means that it is not produced from recycled materials. · Secondary Aluminum: Aluminum is also metal as an end product which is obtained from recycled waste material. Aluminium is 100% recyclable without any loss of its natural qualities. Recycling aluminum requires only 5% of the energy used to produce aluminum from primary natural inputs
