Bauxite Deposits an overview ScienceDirect Topics

Bauxite deposits invariably contain a range of impurities, ranging from organic material to trace elements such as Ga, Zn, Pb, P and Be. Table 2.1 shows typical compositions of a range of smelter aluminas. In the Bayer process, many impurities are at least partially soluble in the caustic digestion liquor and may be carried over into precipitation if they are not removed in

Mining and Refining Process World Aluminium

On some surface deposits there is no overburden, and on others, the bauxite may be covered by up to 20 metres of rock and clay. On average, overburden thickness is around 2 metres. The bauxite layer beneath the overburden is broken up using methods such a blasting, drilling and ripping with very large bulldozers.

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
