AbstractPrecipitation of monosodium aluminate hydrate (MAH) from concentrated sodium aluminate solution in the hydro-chemical process of alumina production was carried out in a continuously operated crystallizer. Crystal size distribution and morphology of MAH crystals were greatly influenced by parameters in the crystallization process, including mean residence time, supersaturation, temperature and agitation. Spherical MAH crystals with uniform size were successfully obtained. A condition of the mean residence time of 50 min, the temperature of 60 degrees C, the supersaturation of 5.3 and the agitation speed of 300 rpm was preferred in the precipitation of MAH crystals.
