BISHOPHITE FROM SALT LAKES BARSAKELMES

Abstract

the process of concentration of brine from Lake Barsakelmes by evaporation in two blunts was studied. The concentration of magnesium chloride after the first stage of evaporation is 15-16%, and after the second 19-19.5%. In this case, precipitated the crystals of sodium chloride, easily separated from the solution. Further, the processes of desulfurization and desalination of a solution of sodium and magnesium chlorides by distillation liquid and sodium carbonate carried out. By further evaporation of the purified suspensions of magnesium and sodium chlorides, a bischofite melt with a content of at least 46.9% MgC12 and crystals of sodium chloride with a content of 98% NaC1 obtained.
