Aluminium Production Process

Aluminium production process

The aluminium production process starts with the mining of bauxites, an aluminium rich mineral in in the form of aluminium hydroxide. About 90% of global bauxite supply is found in tropical areas. ALUMINA PRODUCTION. Bauxite is crushed, dried and ground in special mills where it is mixed

Production process EUROPEAN ALUMINIUM

Pure aluminium oxide, called alumina, is extracted from bauxite via a process called refining, composed of two steps: a digestion process, using caustic soda, which allows the separation of aluminium hydroxide from the so-called “bauxite residue”, followed by a calcination step which removes the water content in the hydroxide.

How aluminium is produced

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.

Het productieproces van aluminium Comhan Aluminium

Aluminium wordt gewonnen uit bauxiet. Bauxiet is de benaming voor het erts waar ongeveer 30 tot 54% aluminiumoxide in zit. Omdat aluminium de sterke neiging heeft om zich te binden met zuurstof, vindt men in de natuur namelijk geen zuiver aluminium. Aluminium is alleen aanwezig in de vorm van een oxide, metaal gebonden aan zuurstof.
