The evaporation of a Tunisian brine sample involving the system Na+, K+, Mg2+/ Cl- SO4 2--H2O was studied under atmospheric pressure and at temperature roomequal to 298 K. The selective densities of precipitation of halite (NaCl) and the co-precipitation of halite and sylvinite (KCl), and the co-precipitation of halite sylvinite and epsomite (MgSO4.7H2O), were determined. The sequence of crystallization determined experimentally has been compared with the theoretically sequence.
