%X Based on the problem of higher Al2O3/SiO2 (A/S) of Bayer red mud, the separation of Al and Si in red mud from Bayer process in digestion with NaOH sub-molten salt was investigated. The effects of digestion temperature, mass ratio of alkali to red mud from Bayer process and CaO addition on the behavior of red mud in the salt were experimentally investigated. The results show that high temperature and mass ratio of alkali to red mud lead to more alumina into the aqueous phase and the decrease of A/S in brown ...
