A Pitzer model representing the thermodynamic properties of synthetic Bayer liquor solutions, consisting of the components NaOH - NaAl(OH) 4-Na2CO3-Na2SO 4-NaCl-NaF-Na2C2O4 (sodium oxalate)-NaHCOO (sodium formate)-NaCH3COO (sodium acetate)-H 2O, is presented. The model calculates, in a thermodynamically consistent manner, heat capacities, enthalpies, activity and osmotic coefficients, and densities of these solutions as well as the solubilities of gibbsite, Al(OH)3, boehmite, AlOOH, sodium oxalate, sodium sulfate and other relevant solid phases in synthetic Bayer liquors over concentration and temperature ranges of industrial interest.
