Research of bittern concentration processes lake Karaumbet and Barsakelmes

The conducted studies on the concentration of brine from lakes Karaumbet and Barsakelmes under conditions close to industrial ones showed possibility obtaining practically pure sodium chloride magnesium melt. To do this, evaporation process must be carried out in two stages. a density 1.550 g/sm 3 increases content 7.20% 28.24%. At same time, ions decreases 8.05% 0.91%. at first second stages 1.340-1.345 , which contributes release into precipitate. mother liquor makes it possible obtain chloride. after stage is 15-16%.
