Aluminum ore, also known as bauxite, is a naturally occurring mineral rock that contains aluminum in the form of aluminum oxide (Al2O3) mixed with various impurities. Bauxite is the primary source of aluminum, which is one of the most abundant elements in the Earth's crust, comprising about 8% by weight.
Hydrated aluminium oxides present in the bauxite are diaspore and bohemite, Al2O3, H2O (Al2O3-85%, Al-45%); gibbsite or hydragillite, Al2O3, 3H2O (Al2O3-65.4%, Al-34.6%) and bauxite (containing colloidal alumina hydrogel), Al2O3 2H2O (Al2O3-73.9%, AI-39.1%) Iron oxide in bauxite ore is present as hematite or goethite, Silica occurs partly as ...

Bauxite is the principal ore of aluminum and is a mixture of aluminum oxides and hydroxides that formed from intense chemical weathering of a soil in tropical environments. Soils formed under these conditions are termed laterites. In Arkansas, the aluminum-enriched soils are the result of the decomposition and lateritic weathering of nepheline syenite, an intrusive …
Bauxite is the most common ore of aluminium. Extraction of aluminium metal takes place in three main stages: mining of bauxite ore, refining the ore to recover alumina, and smelting alumina to produce aluminium. Other raw materials are mined as aluminium ore, but their use is minor compared with bauxite.
Keeping the above characteristics in view, several west coast lateritic bauxite mines of India employ dry crushing−screening process to bring down silica content from the metallurgical grade bauxite [].Recently, a bauxite mine of Guinea known as AGB2A has also adopted the dry beneficiation procedure to cut down silica from about 7% to below 3%, to make this one the …
