Extraction of Aluminium (Aluminium Ore) Hall

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. Aluminium oxide in water does not dissolve, but in molten cryolite, it dissolves.

How is bauxite processed into 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

refining aluminum bauxite ore process line diagram

Alumina is produced from bauxite, an ore that is mined from topsoil in various tropical and subtropical regions. The Bayer process, discovered in 1887, is the primary process by which alumina is extracted from bauxite. To produce pure aluminum, alumina is smelted using the Hall–Héroult electrolytic process.

process from bauxite to aluminium

Mining and Refining Process World Aluminium. The Bayer Process is the most economic means of obtaining alumina from bauxite. Other processes for obtaining alumina from metal ores are also in use in some refineries, particularly in China and Russia, although these make up a relatively small percentage of global production.

GCSE CHEMISTRY Extraction of Aluminium

2017-3-27  Extraction of Metals. Extraction of Aluminium.. Aluminium ore is called bauxite. Bauxite contains aluminium oxide, water, iron oxide and other impurities. The purified dry ore, called alumina, is aluminium oxide Al 2 O 3.. The alumina must be molten for electrolysis to work, since the ions are not free to move in the solid state. Unfortunately, alumina has a high melting point (2040 °C)

Chapter 2. Production and Processing of Aluminum

1999-5-7  Bauxite occurs mainly in the tropics and in some Mediterranean countries. Today, the main mining locations are in Latin America, Australia, India, and Africa. Bauxite is a weathered rock containing two forms of hydrated aluminum oxide, either mostly a monohydrate AlO(OH) in caustic bauxite, or mostly a trihydrate Al(OH) 3 in lateric bauxite.

2004-3-9  Extraction of aluminium. Aluminium is extracted from it's ore by electrolysis. The electrolyte has to be molten ore, if a solution was used (as in the extraction of copper) hydrogen gas would be produced instead of the pure metal. The next problem lies in that aluminium ore, bauxite, has a very high melting point over 2000 degrees Celsius!
