Study of the Influence of Evaporation on the Concentration of Solutions of the Lakes Karaumbet and Barsakelmes

This investigation into brine from two specific lakes such as Karaumbet and Barsakelmes suggests that NaCl and MgCl2 melts can be made into industrial-like conditions.A two-step evaporation method is key to this process.In the first step, evaporating to a density of 1.550 g/cm 3 raises magnesium chloride concentration from 7.20 to 28.24% and drops sodium ion levels from 8.05 to 0.91%.The evaporation should continue at the first and second stages until a density of 1.340-1.345g/cm 3 is reached, which causes sodium chloride to form.Further evaporation of the remaining liquid can yield almost pure sodium chloride.After the initial evaporation phase, magnesium chloride in the brine is at 15-16%.
