Abstract

The article presents the results of nitric and sulfuric acid decomposition of unfortified phosphate rock. In order to determine the degree of decomposition of phosphate raw materials, depending on the concentration and rate of sulfuric acid, the calculated amount of phosphorite was treated with an acid with thorough stirring for 20 min. The resulting product, after cooling and after drying at a temperature of 105-110 °C, was subjected to chemical analysis. Fertilizer production by decomposition of low-grade phosphorites at an incomplete rate of concentrated sulfuric acid and weak nitric acids occurs in a solid-phase mode and differs from classical methods in that when the interaction of the components is completed, the resulting mass is constantly fragmented into small aggregated particles, which, in turn, are continuously enveloped with excess phosphate raw materials
