PROCESS DESCRIPTION: BAUXITE MINING. Bauxite is the principal ore of alumina (Al 2 O 3), which is used to produce aluminum (Al). It is composed of hydrated aluminum oxides, hydrated aluminosilicates, iron oxides, hydrated iron oxides, titanium oxide, and silica. It contains mixtures of various minerals such as gibbsite, boehmite, hematite ...

The spent liquor is heated through a series of heat exchangers and subsequently cooled in a series of flash tanks. The condensate formed in the heaters is re-used in the process, for instance as boiler feed water or for washing bauxite residue. The remaining caustic soda is washed and recycled back into the digestion process. 7. Classification
