Claims (4)

1. Способ получения сложного азотно-фосфорного удобрения на основе нитрата аммония с добавкой фосфата в пересчете на Р2О5 в количестве не менее 2 мас.%, включающий ступенчатую нейтрализацию аммиаком азотной кислоты, упарку нейтрализованного раствора, введение фосфатной добавки и грануляцию продукта, отличающийся тем, что в качестве фосфатной добавки используют фосфорсодержащие соединения кальция.1. A method of obtaining a complex nitrogen-phosphorus fertilizer based on ammonium nitrate with the addition of phosphate in terms of P 2 O 5 in an amount of not less than 2 wt.%, Including stepwise neutralization of ammonia with nitric acid, evaporation of the neutralized solution, introduction of a phosphate additive and granulation of the product, characterized in that phosphorus-containing calcium compounds are used as phosphate additives. 2. Способ по п.1, отличающийся тем, что в качестве фосфорсодержащих соединений кальция используют осадок фосфатов, образующийся при разделении предварительно аммонизированной пульпы, полученной при азотнокислотном или солянокислотном вскрытии апатитового концентрата.2. The method according to claim 1, characterized in that as a phosphorus-containing calcium compounds, a precipitate of phosphates is used, which is formed during the separation of pre-ammoniated pulp obtained by nitric acid or hydrochloric acid opening of apatite concentrate. 3. Способ по п.1, отличающийся тем, что содержание фосфатов в пересчете на P2O5 в удобрении составляет 2-9 мас.%, азота 27-32 мас.%.3. The method according to claim 1, characterized in that the phosphate content in terms of P 2 O 5 in the fertilizer is 2-9 wt.%, Nitrogen 27-32 wt.%. 4. Способ по п.1, отличающийся тем, что фосфатную добавку вводят в плав аммиачной селитры.4. The method according to claim 1, characterized in that the phosphate additive is introduced into the melt of ammonium nitrate.
