Aluminium Profile Manufacturing
Aluminium is a metal that is not found in nature in its pure state, being a component found in Bauxite. This ore was found by French physicist and mineralogist Pierre Berthier in 1821 in the town of Les Baux. It was given the name Bauxite as a mention of the town where it was found. At that time, aluminium was not yet known, as it was only separated from Bauxite in 1824 by the Danish physicist and chemist Hans Christian Oersted, through a chemical solution.
In 1854, the French chemist Henry Saint Claire Deville succeeded in obtaining aluminium by heating a solution of ammonium chloride and sodium.
Some time later, Deville's process was changed to an electrolytic process by Paul Louis Toussaint Heroult (Normandy-France) and Charles Martin Hall (Ohio - United States). Heroult and Hall, without knowing each other, they invented at the same time the procedure that marked the beginning of aluminium production.
Bauxite is found in abundance in the tropical and subtropical regions of the planet, in a rocky or granular formula with various shades depending on its composition.
Economic development is directly linked to the production of aluminium, where infrastructural factors are fundamental, such as hydraulic and energy resources and the capacity to recover the waste produced in the process of obtaining this metal. At the end of the 20th century, the main producers of aluminum were the United States, Canada, Australia, Brazil and Germany.
Currently, more than 13 million tons of aluminium are produced per year.
