Handling of bauxite Loading, discharging environmental

Bauxite is an aluminium ore and is the main source of aluminium. This form of rock consists mostly of the minerals gibbsite Al(OH)3, boehmite y-AlO(OH), and diaspore a-AlO(OH), in a mixture with the two iron oxides goethite and hematite, the clay mineral kaolinite, and small amounts of anatase TiO2 A brownish-yellow clay-like and earthy mineral.

Reactions of kaolinite in the predesilication processing

Bauxite ores, primarily a mixture of hydrated aluminium oxides, are refined to gibbsite (γ-AI(OH)3) by dissolution in superheated concentrated sodium hydroxide and reprecipitation from the cooled liquor in the Bayer process. The raw bauxite ore also contains iron oxides, organic materials, quartz and aluminium silicates such as kaolinite.

Comparison of two NIR systems for quantifying kaolinite

The mineral kaolinite, also termed reactive silica, is the primary source of soluble silicates and hence a significant expense in the refinement process. Estimated soda losses can account for as much as 20% of alumina production costs in high silica bauxites . Precise determination of kaolinite content is therefore important to bauxite mining
