Recovery of salt co-products during the salt production from brine

Sodium chloride and the secondary salts, such as sylvite, mirabilite, thenardite, bloedite, carnalite, bischofite, kieserite and polyhalite are not only mined from evaporate deposits, but they have also been produced more economically by solar concentration of brines for centuries. In this study, as an alternative approach, the aim was to create the production of salt co-products together with pure sodium chloride (NaCl) during the NaCl producing period from the Salt Lake water by multiple evaporation-cooling methods, supplemented by mineral and chemical processing. The results of XRD analysis indicated that various types of salts such as pure halite (sodium chloride), sodium sulphate salts, halite + carnalite, halite + langbeinite + sylvite and halite + bischofite + kieserite can be produced as participated materials from the brine of the Salt Lake.
