Chapter 2. Production and Processing of Aluminum

The starting material for electrolytic smelting of aluminum is pure, anhydrous alumi-num oxide (Al 2 O 3) called alumina. In the Western World, the Bayer 1 process, invented in the 19th century, is by far the most important process used in the production of alumi-num oxide from bauxite. The process has been refined and improved since its inception.

Aluminum die cast parts are corrosion resistant, highly conductive, have a good stiffness and strength-to-weight ratio. The aluminum die casting process is based on rapid production that allows a high volume of die casting parts to be produced very quickly and …

Aluminium - Essential Chemical Industry

Aluminium can be easily recycled at low cost (using about 5% of the energy required for primary production) and approximately 60% of European consumption is recycled metal. It has even been estimated that two-thirds of all the aluminium manufactured since commercial production started in1886 is still in use today.

How aluminium is produced

The next stage in the production chain is the processing of bauxite into alumina, or aluminium oxide - Al 2 O 3, - a white powder.The most common process for making alumina from bauxite is the Bayer process, which was first discovered over 100 years ago but is still in wide use today.

Production process - European Aluminium

Molten aluminium is extracted from the alumina through an electrolytic process called smelting, which breaks the strong chemical bond of the aluminium and oxygen atoms using a powerful electric current. Once the liquid metal is collected it is transferred in the casthouse, where it is purified, alloyed to specification and then cast into ingots.
