2009-3-1  In China, low grade diasporic bauxite with an Al 2 O 3 /SiO 2 mass ratio below 8 can be processed by sintering, or through a combination of sintering and the Bayer process (Liu et al., 2007). Ores whose Al 2 O 3 /SiO 2 mass ratio is greater than 10 can be directly processed by the Bayer process. Depending on this ratio, poorer ores can be fed to specially designed refineries.
