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

Bauxite has been a priority sector for the upstream aluminium value chain players for some time now. The supply certainty of the ore plays a crucial role in controlling the logistics cost of the sector which in turn helps in optimising the overall cost of production of aluminium. With China’s appetite for bauxite growing bigger combined with supply-side concerns arising from

Jun 21, 2019· Bauxite seaborne trade is set to grow sharply over the next decade, which will increase diversity of supply. Bauxite ores differ in quality according to location. An ore that is economical and suits the technical needs of one refinery might be a poor source for another. This makes pricing challenging.
