摘要：
A process is disclosed for the production of ammonium phosphates starting from phosphate rocks, comprising a grinding of such rocks, a chemical attack with sulphuric acid and ammonium sulphate, and a filtration of the reaction pulp, characterized in that the chemical treatment of the rocks is carried out in one single stage under isothermal conditions at a temperature ranging from 70 of 90°C.
