Mineral transformation in treating low-grade bauxite using ...

During the Bayer process for alumina production, the molecular formula of the bauxite residue is approximately equivalent to Na 2 O·Al 2 O 3 ·1.7SiO 2 ·nH 2 O. This means that 1 kg of SiO 2 in bauxite will produce 1 kg of Al 2 O 3 and 0.608 kg of Na 2 O in bauxite residue. Thus, the extraction efficiency of alumina is low when processing low-grade bauxite.

An ore that is self-fluxing may be of lower grade for direct smelting than one that requires the addition of a large amount of barren flux. On the other hand, a low-grade ore sometimes may be profitably mined and shipped direct because it is high in silica, iron, or lime, or some other fluxing material required by the smelter.
