Abstract

In this study, the process of activation of off-balance phosphorite ore of the Central Kyzylkum desert (14,33% P205) by extraction phosphoric acid (14,32% P205) with the addition of sulfuric acid (93%) at 75 °C, reaction time 30 min. at different mass ratios P205PAE: P205FC andP205PAE : H2SO4mng. It is shown that the addition of H2SO4 significantly intensifies the process of phosphoric acid activation of the phosphate mineral of the raw material. The water-insoluble part of the products of phosphoric acid activation with the addition of sulfuric acid has been studied. It has been shown that both the fertilizer itself and it’s water-insoluble part contain a significant amount of the P2O5 form assimilable for plants.
