Abstract
Process for the manufacture of fertilizers based on ammonia phosphates, characterized in that it consists in reacting in a first cell phosphoric acid optionally mixed with other acids, and gaseous ammonia, optionally liquid or in aqueous solution, so that the NH3/PO4 ratio of this cell is located in the vicinity of 0.80, and by reacting in a second cell the product of the reaction obtained in the first with ammonia, so that the NH3/PO4 ratio is in the vicinity of 1. , 5, and finally, that the final adjustment of the molecular ratio NH3/PO4 is carried out in a granulator by the addition of ammonia, optionally of an acidic material.
