The effect of the quantity and concentration of calcium nitrate solutions on the qualitative parameters of fertilizer precipitates obtained on the basis of mineralized mass (MM) was studied. For laboratory experiments, we used MM with the following composition (wt.%): 14.60 - P2O5, 43.99 - CaO; 14.11 - CO2, 1.58 - SO3; 10.82 - n.d .; CaO: P2O5 = 3.01. The optimal ratios and concentrations of calcium nitrate were determined: the ratio of MM : solution Ca(NO3)2 = 1 : 2.0 and the concentration of calcium nitrate solution - 10 and 15%. With optimal parameters, a fertilizer precipitate of the following composition (wt.%) Is obtained: P2O5total. = 23.60-23.68; P2O5ac.c.a.. by citric acid = 12.67-12.72; P2O5water solubility = 2.10-2.11; СaOtotal. = 43.36-43.39; СaOac.c.a. by citric acid = 24.19-24.24; СaOwater solubility = 4.24-4.35; N = 1.77-1.82. The degree of removal of Ca(NO3)2 from fertilizer precipitates is 97.07-97.42%. This produces the main filtrate containing 20.70-22.52% Ca(NO3)2.
