Aluminium
Bauxite is the most common aluminium ore. Bauxite occurs as a weathered cover or blanket, known as laterite or duricrust, over a variety of alumina-bearing rocks. It forms when large amounts of rainfall leach away the more mobile elements in the host rock leaving the relatively immobile aluminium with some silicon, iron and titanium. Because …
Bauxite Mining and Alumina Refining
The bauxite ore contains aluminum trihydrate (Al(OH) 3). Alumina refining produces alumina (Al 2 O 3) from the bauxite ore, by exploiting the reversible reaction of the Bayer process 1–3: The reaction is firstly driven in the sodium aluminate (NaAlO 2) direction by the addition of caustic soda (NaOH) to bauxite. Bauxite residues are then ...
Bauxite
In the bauxite refining process, the aluminum-bearing minerals in bauxite are converted in a multiple-step process to alumina (Al2O3). Alumina can be smelted to form metallic aluminum or it can be used as the source of many other products, including refractory materials used to line high-temperature rotary kilns and metallurgical furnaces.

Extraction of Aluminium (Aluminium Ore)
Bauxite ore (Al 2 O 3.xH 2 O) is the major source of aluminium till date which is a mixture of hydrated aluminium oxide. Aluminium can also be recovered from cryolite (Na 3 AlF 6) and alunite. It is also found in gemstones such as garnet, topaz and chrysoberyl. The chemical symbol of this metal is Al.
Conversion of Bauxite Ore to Aluminum Metal
Bauxite Ore Processing. Aluminum is found in varying amounts in nature as aluminosilicates (contains aluminum, silicon, and oxygen) in various types of clay. As the minerals are weathered they gradually breakdown into various forms of hydrated aluminum oxide, Al 2 O 3.xH 2 O, known as bauxite. The bauxite is purified by the Bayer Process. …
Bauxite in Jamaica
Bauxite is the ore from which aluminium is made. Jamaica contains some of the largest known deposits of bauxite in the world.
