Abstract

Results of researchers of the conversion process of flotation potassium chloride of the Tyubegatan field with the mirabilite of the Tumryuk field and the production of glaserite are presented. With an increase in the molar ratio of KCl:Na2SO4 from 1:0.8 to 1:1.4, the content of Na2O in glaser increases from 8.52% to 11.68%, while the content of K2O decreases from 41.61% to 36.78% chlorine from 4.13% to 3.28%. In the composition of the liquid phase, the K2O content decreases from 10.50% to 5.20%, Na2O from 12.46% to 8.90%, chlorine ions from 16.81% to 8.23% and only the content of SO42- ions increases from 2.96% to 8.96%. With an increase in the liquid phase (L:T), the content of K2O in the composition of the solid phase increases, and the content of Na2O and chlorine ions decreases. At T:L = 1:0.8, the content of K2O is 38.08%, and at T:L = 1:2.0 it is 42.40%, the content of Na2O decreases from 10.31% to 7.00%, of ions chlorine from 4.24% to 2.60%, the composition of the liquid phase contains 7.87-4.36% K2O, 13.20-8.50% Na2O, 3.27-2.56% SO42- ions, 18, 67-11.03% of chlorine ions.
