Process and apparatus for the manufacture of ammonium nitrate, characterized in that aqueous nitric acid is neutralized by ammonia in a solution of ammonium nitrate circulating in a closed circuit in apparatuses in which the pressure is higher in the area where it is effected. Neutralization in the area in which, at the expense of the heat of reaction, evaporation is carried out in order to preconcentrate the nitrate solutions before their eventual shipment to a final concentrator.
