Concentration of Wet Process Phosphoric Acid From Washed Thermo Concentrate of Phosphorites Central Kyzylkum and Its Rheological Properties

Year: 2025

Type: article

Abstract: The process of purification and concentration of wet process phosphoric acid (WPA) creates the possibility of obtaining more concentrated phosphorus - containing products, such as ammonium dihydrogen phosphate and ammonium hydrogen phosphate, calcium dihydrogen phosphate and calcium dihydrogen phosphate, liquid complex fertilizers for drip irrigation. WPA from the washed thermo concentrate (WTC), although low concentrated (≥ 20 % Р2О5 ), contains alone 0.3 - 0.5 % MgO and is suitable for concentration by evaporation. To obtain concentrated phosphoric acid, it is necessary to carry out the processes of desulfurization and evaporation of the Kyzylkums WPA.
