STUDY OF PROCESSE OF OBTAINING MONOPOTASSIUM PHOSPHATE BASED ON MONOSODIUM PHOSPHATE AND POTASSIUM CHLORIDE

Abstract

Results of studies of the process of conversion of the flotation potassium chloride of the Tyubegatan deposit with solutions of sodium dihydrogen phosphate obtained on the basis of purified extraction phosphoric acid from phosphorites of the Central Kyzylkum to potassium dihydrogen phosphate are presented. The effect of the ratio of the components, S:L on the formation of potassium dihydrogen phosphate at temperatures of 25°C and 100°C was studied. Optimal technological parameters for isolation of potassium dihydrogen phosphate were determined. Rheological properties of solutions formed in the process of obtaining potassium dihydrogen phosphate were identified. The obtained results were confirmed by X-ray phase and IR-spectroscopic methods of analysis. Elemental composition of potassium dihydrogen phosphate was established by electron microscopy.
