Getting Hydrated Magnesium Chloride from Magnesium Chloride Solutions of Potassium Sulfate Fertilizers Production

Basystiuk Ya І and Kostiv IY

This article presents the results of research of the process of cleaning magnesium chloride solution potash production from impurities of potassium chloride and sodium- cooled lighted solution after separation kainite and for the sulfates the evaporation to getting a suspension of finely dispersed sulfate salts (kieserite, langbeinite) in a concentrated solution of magnesium chloride, cooling, which leads to the crystallization of magnesium chloride. At the expense of differences in size, structure and energy of crystals of sulfate minerals and hydrated magnesium chloride different crystalline phases and separated by hydrodynamic method have been formed. The suspension of finely dispersed sulfate minerals with solution have been returned on crystallization kainite and thickened sediment hydrated magnesium chloride has been filtered on a centrifuge to produce a finished product
