Chapter 2 Production And Processing Of Aluminum
Chapter 2. Production and Processing of Aluminum 2.1 Extraction of Aluminum The extraction of aluminum from its ore and subsequent processing into finished prod-ucts takes place in a series of successive operations, each largely independent of the other. Generally the various processes are carried out at different plant sites. A summary of

How Aluminium Is Produced
Slabs are usually then rolled into thin sheets that are then used in the manufacture of foil, beverage cans or automobile body panels. 7 metre long aluminium billets are used to make extrusions - this is when the billet is pushed through a hole of the required shape. Extrusion is the process used for making the vast majority of aluminium products.
Extraction Of Aluminium Aluminium Ore Hallheroults
The ore is then concentrated by chemical process. Bauxite is the name given to aluminium ore. To generate aluminium oxide, bauxite is purified, a white powder form which aluminium can be extracted. Aluminium oxide has a very high melting point of more than 2000 C so melting it would be costly.

been from ore first discovered by the Remans.3 At Rio Tinto, the Remans mined the upper, ox-idized, part of the ore and collected the copper-Iaden solutions produced by water slowly seep-ing down through the suIfide ore bodies. When the Moors conquered this part of Spain during the Middle Ages, the oxide ores had largely been exhausted.

Roll forming is a fairly common method of aluminum processing, which, as it proceeds, makes aluminum more ductile and less brittle. This method is used to make both very thin products, such as aluminum sheets, aluminum plates, aluminum coils, aluminum strips, and hollow products, such as aluminum pipes and aluminum tubing.
