Abstract


Background. In the production of phosphate fertilizers and phosphoric acid accumulation environmentally unsafe on the course – phosphogypsum. To date, in theterritory of Ukraine is in the dumps about 30 million tons of phosphogypsum.

Objective. To get from phosphogypsum with using waste technologies complex NPCaS-fertilizer.

Methods. Processing phosphogypsum in a relatively “soft” operating conditions, without the involvement of high-temperature (1173–1753 K) processes. Conducted a research of two-stage utilization processing of typical phosphogypsum into complex fertilizer with composition 7,9 % N, 37 % P2O5, 35 % Ca, 1,8  % S, containing phosphorus in the form of Сa(H2PO4)2, СaHPO4 (at a ratio ), and the nitrogen – in the form (NH4)2SO4. The first stage of the process is implemented decomposition of phosphogypsum at temperature (323 ± 5) K by solutions of (NH4)2СOat pH > 5,1 with formed a precipitate (suspension) СаСO3 in solution (NH4)2SO4. In the second stage formed a thick slurry is processed (without filtration separation СаСO3) by solutions of sub-standard phosphoric acid without external heating at the support of the pH of the medium to 6,8–6,9. The final solid fertilizer is drying of slurry in apparatus of type “fluid process” at temperature (390–423) K.

Results. The final solid fertilizer, consumer quality is tested on samples of soil for agricultural purposes.

Conclusions. On the base of phosphogypsum is received a complete fertilizer for little-stage non-waste technology in environmentally sound conditions.
