  This paper presents the results of laboratory researches evaporation processing solutions polymineral salt material that contain sulfates and chlorides of potassium, magnesium and halite. Determined degree of evaporation and temperature of the suspension in which achieved the highest level of separation ions of potassium and sulfate in the solid phase, and the solid phase-the highest content kainite and the lowest-sylvine and carnalite. The lowest content (2.6-5.7%) of carnalite in suspension achieved at temperature of 313-333 ? and the degree of evaporation 19.2-26.5%. Cooling of the suspension with the degree of evaporation of 30.1% is not necessary, because it leads to increased degree of separation in the solid phase of carnalite. Regulate the depth of evaporation and cooling can be by concentrate on in the liquid phase of equivalents MgSO4 (0.016-0.032), MgCl2 (0.248-0.289), and the.. View More»
