Bauxite ore Britannica

The laterite type is commonly pisolitic and mottled, with pisolites ranging in size from about 2.5 mm (0.10 inch) to 25 cm (10 inches) or more in diameter. Both pisolites and groundmass (matrix) may exhibit great colour variations; common colours are pink, cream, red, brown, yellow, and gray. Exposed surfaces of lateritic ore are rough, often lavalike, with a wormlike structure and variegated colours on vertical

Bauxite an overview ScienceDirect Topics

The bauxite formed a bed averaging 2 m thick. The bauxite is friable and reddish-brown, contains boulders of all sizes up to 12 m diameter of gabbro, which would hinder mining. The core of the boulders is fresh, with a thin skin of bauxite. The bauxite ranged from 45–53% A1 2 O 3 and contains 64–78 % gibbsite. A thick bed of kaolinite, goethite and some gibbsite underlies the bauxite. The parent rock is

Bauxite Wikipedia

Bauxite is a sedimentary rock with a relatively high aluminium content. It is the world's main source of aluminium and gallium.Bauxite consists mostly of the aluminium minerals gibbsite (Al(OH) 3), boehmite (γ-AlO(OH)) and diaspore (α-AlO(OH)), mixed with the two iron oxides goethite (FeO(OH)) and haematite (Fe 2 O 3), the aluminium clay mineral kaolinite (Al 2 Si 2 O 5 (OH)) and small

4 Beneficiation Processes to Obtain Aluminum from

The first process of the Bayer is to crush the bauxite ore into granules with a diameter of about 30 mm. Then wash away the impurities such as clay on the surface of the granules. The important thing is that you can mix the washed particles with the reused Bayer process liquid phase with a sodium hydroxide concentration of 30% -40% to form a suspension with a solid particle size below 300 microns by ball mill.
