Bauxite 101 Bauxite ore is the world’s main source of aluminum. Bauxite is a rock formed from a reddish clay material called laterite soil and is most commonly found in tropical or subtropical regions. Bauxite is primarily comprised of aluminum oxide compounds (alumina) silica
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 aluminumenriched soils are the result of the decomposition and lateritic weathering of nepheline syenite an intrusive igneous rock.

Bauxite Hills looks to be a relatively simple freedig mining trucking and barging operation. Followers of the sector will have noted the strengthening fortunes of the large alumina producer Alumina (AWC MCap A$4.97b) and the small bauxite producer Australian Bauxite (ABX MCap A$42.9m). We take the
Lateritic Bauxite Deposits Our Largest Source of . Selective mining ensures that only the highest grades are mined. Below the pisolitic bauxite horizon is a nodular ironstone layer. At this level the bauxite becomes increasingly iron and kaolinrich. Kaolinite which contains a great deal of silica is also much lower in aluminium content than
The bauxite mines in the Darling Range have the world's lowest grade bauxite mined on a commercial scale (around 2730% Al 2 O 3). Despite the low grade the mines accounted for 23% of global alumina production as they also have low reactive silica making the bauxite relatively easy to refine.

Jul 20 2002nbsp018332Bauxite is the raw material used for aluminium and alumina production. Its composition production and global distribution are all covered. Also covered are environmentla factors relating to restoring areas subjected to bauxite mining.
Processing of Bauxite Ores To Obtain Aluminum Bauxite the primary aluminum ore uses the Bayer Process to extract alumina from the ore. The processing begins with crushing to 12 inch particles and wet screening to remove some silica fines which are generally present with bauxite.
The silica present in the bauxite tends to be concentrated in the finer grained fractions and this characteristic makes bauxite amenable to beneficiation by screening techniques. Pearson' has reported that in a bauxite of average composition of 1.58% silica the minus 100 mesh fraction analysed a silica content as high as 10.30%.
