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 OAl 2 O 3 17SiO 2 nH 2 O This means that 1 kg of SiO 2 in bauxite will produce 1 kg of Al 2 O 3 and 0608 kg of Na 2 O in bauxite residue Thus, the extraction efficiency of alumina is low when processing low-grade bauxite...
