  In isothermal conditions have been studied the influence of system solution sea salts during their evaporation and crystallization to composition of received liquid and solid phases. It is shown that evaporation of the solution leading to its supersaturation by sulfate salts. In the liquid phase before crystallization of kainite concentration of SO4 2- ions increases to 10% and above. Through this probability of formation of crystals increases and the result of evaporation is the formation of finely dispersed kainite. During crystallization of kainite concentration of SO4 2- in the liquid phase decreases rapidly. Decreasing its intensity increases with increasing value k=E SO4 2- : E Mg2+ of initial solution. For the degree of evaporation of 20.0% and 31.0% concentration of SO4 2- in evaporated solution on the value of k does not change. Most forms of potassium salts in the solid phase f.. View More»
