Bauxite Types and Uses - Australian Bauxite Limited

Bauxite is aluminium-rich ore that is used for aluminium production (the metallurgical bauxites) and for production of refractory materials, chemicals or cements (the non-metallurgical bauxites). Metallurgical bauxites are sub-divided into two basic types based on the processing methods that must be applied to them at the alumina refinery stage ...

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 the desilication ...
