Abstract

The separation of magnesium and aluminum bearing compounds from the (NH4)(2)SO4 aqueous solution is crucial for the ammonium sulfate roasting technique to extract Mg and Al from the magnesium aluminum-bearing slag. Equilibrium solubility data for the quaternary system of MgSO4 -Al-2(SO4)(3)-(NH4)(2)SO4-H2O at 40 and 80 degrees C were therefore measured and compared with those of their ternary subsystems of MgSO4-(NH4)(2)SO4-H2O and Al-2(SO4)(3)-(NH4)(2)SO4 H2O, respectively. The mutual salting-out effect between MgSO4 and Al-2(SO4)(3) in the quaternary system was further discussed. On the basis of the measured data, a strategy for effective separation of magnesium and aluminum compounds from the MgSO4-Al-2(SO4)(3)-(NH4)(2)SO4-H2O system was developed.
