Aluminium smelting
Aluminium smelting is the process of extracting aluminium from its oxide, alumina, generally by the Hall-Héroult processAlumina is extracted from the ore bauxite by means of the Bayer process at an alumina refinery This is an electrolytic process, so an aluminium smelter uses huge amounts of electricity; smelters tend to be located close to large power stations, often hydro-electric ones ....

Aluminium oxide
Aluminium oxide (IUPAC name) or aluminum oxide (American English) is a chemical compound of aluminium and oxygen with the chemical formula Al 2 O 3It is the most commonly occurring of several aluminium oxides, and specifically identified as aluminium(III) oxideIt is commonly called alumina and may also be called aloxide, aloxite, or alundum depending on particular forms or applications...

How an Aluminum Smelter is Made
An aluminum smelter includes the potroom, one or more large buildings housing the electrolysis cells, plus a series of other sub-plants that: produces the rodded anodes for the cells, produces compressed air, delivers the alumina to the cells, treats the fluoride gases escaping from the crust, rectifies the alternate current to produce a suitable low voltage high amperage direct current for ....

How Aluminum is Produced
The smelting process required to produce aluminum from the alumina is continuous the potline is usually kept in production 24 hours a day year-round A smelter cannot easily be stopped and restarted If production is interrupted by a power supply failure of more than four hours, the metal in the pots will solidify, often requiring an expensive ....

Bayer Process
Alton T Tabereaux, Ray D Peterson, in Treatise on Process Metallurgy: Industrial Processes, 2014 2511 Impact of Different Bauxites on the Bayer Process The Bayer process is basically used for the extraction of aluminum hydrate from the bauxite ores with the mass ratio of alumina to silica (A/S) above 9 The sinter process is widely used to process the poor-grade diasporic bauxite ores ....

Energy needed to produce aluminum
After alumina is extracted from bauxite ore, further processing called 'smelting' is necessary to convert it into aluminum In this process, alumina is dissolved in a solution and a strong electric current is applied This process has generally remained unchanged since its invention in 1886...

Aluminium chloride
Aluminium chloride (AlCl 3), also known as aluminium trichloride, is the main compound of aluminium and chlorineIt is white, but samples are often contaminated with iron(III) chloride, giving it a yellow colorThe solid has a low melting and boiling point It is mainly produced and consumed in the production of aluminium metal, but large amounts are also used in other areas of the chemical ....

Aluminium life cycle
Using the Bayer process, alumina (aluminium oxide) is extracted from bauxite in a refinery The alumina is then used to produce the primary metal at a ratio of 2:1 (2 tonnes of alumina = 1 tonne of aluminium) 3 Primary production The aluminium atom in alumina is bonded to oxygen and needs to be broken by electrolysis to produce aluminium metal...
