The article presents data on the development of technology for defluoridation and desulfation of extraction phosphoric acid from phosphorites of the Central Kyzylkum region with sodium salts. The rheological properties of the suspension and the filterability of the pulp were studied. Optimal norms of the technological regime have been established, at which the mass ratio of liquid: solid in the suspension is not higher than 7:1, the pressure drop ∆P is 70-80 kPa, the concentration of polyacrylomide in the suspension is 2.0-3.5 mg/l, the height of the sediment layer is filter – 0.01 m.
