Production Process - Aluminium Bahrain

The aluminium metal is made of alumina which is composed from aluminium and oxygen. During the smelting process, aluminium and oxygen are separated to produce aluminium metal. To produce one tonne of aluminium, about two tonnes of alumina is required. Electrical energy is used in the smelting process to separate the aluminium metal from the oxygen.

How aluminium is produced

Alumina Production. 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.

Aluminium smelting - Wikipedia

Principle. Aluminium is produced by electrolytic reduction of aluminium oxide dissolved in molten cryolite . Al 3 + + 3 e − Al {\displaystyle {\ce {Al^3+ + 3e- -> Al}}} At the same time the carbon electrode is oxidised, initially to carbon monoxide. C + 1 2 O 2 CO {\displaystyle {\ce {C + 1/2O2 -> CO}}}

Aluminium oxide - Wikipedia

Alumina is used to manufacture tiles which are attached inside pulverized fuel lines and flue gas ducting on coal fired power stations to protect high wear areas. They are not suitable for areas with high impact forces as these tiles are brittle and susceptible to breakage.
