Abstract

Process of receiving two types of fertilizers by division into liquid and solid phases of products of fosfornosernokislotny expansion of the mineralized mass (MM) Central Kyzylkumov is studied. In that case, mass ratio WPA : ММ was 100:15 while amount of H2SO4mng ranged 2 tо 5 g. The distribution rate of components (Р2О5, СаО, MgO, AI2O3, Fe2O3, N, SO3) on phases was estimated. It was shown that the enriched superphosphate with good physicochemical properties could be obtained from the solid phase while concentrated ammophosphate exceeding ammophos by quality considerably based on the liquid phase.
