Abstract
Sebkha El Melah Natural Brine is a complex high concentrated aqueous solution. To study this kind of saline solutions many authors assimilate them to a quinary system represented by Na+, K+, Mg2+/Cl-, SO42-//H2O. In the case of Sebkha El Melah brine, magnesium and sulfate ions seems to be sufficiently high to recover Epsomite (MgSO4.7H2O). The aim of this work is firstly to apply the above mentioned diagram allowing the production of the considered salt, calculate the recovery rates and secondly to test the conceived process at the laboratory scale.
