Bauxite definition: Bauxite is a clay-like substance from which aluminium is obtained . | Meaning, pronunciation, translations and examples
Bauxite occurs also near Ballintoy. After being dried at loo° C., Antrim bauxite contains from 33 to 60% of alumina, from 2 to 30% of ferric oxide, and from 7 to 24% of silica, the balance being titanic acid and water of combination.
Bauxite is the main ore of aluminium. It is mostly aluminium oxide. Bauxite is the most important aluminium ore. It is largely made up of the minerals Gibbsite Al(OH) 3, Boehmite γ-AlO(OH), and Diaspore α-AlO(OH), together with the iron oxides Goethite and Hematite, the clay mineral Kaolinite and small amounts of Anatase TiO 2.
What is Bauxite? Many people are surprised to learn that bauxite is not a mineral. It is a rock composed mainly of aluminum-bearing minerals. It forms when laterite soils are severely leached of silica and other soluble materials in a wet tropical or subtropical climate.
The aluminium-containing bauxite ores gibbsite, böhmite and diaspore are the basic raw material for primary aluminium production. Proven, economically viable reserves of bauxite are sufficient to supply at least another 100 years at current demand.
