1. Способ получени  концентрированного фосфорного удобрени  путем репульпации гор чего камерного суперфосфата с последующим разделением полученной пульпы и отделением фосфогипса, отличающийс  тем, что, с целью упрощени  процесса разделени  и увеличени  содержани  серы в удобрении, из полученной пульпы предварительно отдел ют от 40 до 70% концентрированной жидкой1. A method of producing concentrated phosphorus fertilizer by repulping hot chamber superphosphate followed by separation of the resulting pulp and separation of phosphogypsum, characterized in that, in order to simplify the separation process and increase the sulfur content in the fertilizer, the resulting pulp is previously separated from 40 to 70% concentrated liquid фазы с содержанием Р205 от 25 до 40% и сульфата кальци  от 5 до 25%, а выделенную твердую фазу подкисл ют серной кислотой, вновь репульпируют, сгущают и фильтруют с последующим отделением фосфогипса.the phases with P205 content from 25 to 40% and calcium sulfate from 5 to 25%, and the isolated solid phase is acidified with sulfuric acid, repulped again, concentrated and filtered, followed by separation of phosphogypsum. 2.Способ по п. 1,отличающийс  тем, что разделение пульпы провод т в гидроциклоне .2. A method according to claim 1, characterized in that the separation of the pulp is carried out in a hydrocyclone. 3.Способ по п. 1, отличающийс  тем, что оставшуюс  часть жидкой фазы направл ют на репульпацию камерного суперфосфата.3. A method according to claim 1, characterized in that the remaining part of the liquid phase is directed to repulping the chamber superphosphate.
