Process for the production of phosphoric acid, characterized in that it is effected by exothermic reaction in an aqueous magma, resulting from the mixture of ground phosphate rock and sulfuric acid, in which the magma preferably flows continuously through several successive reaction zones, said method comprising subjecting at least a part of the magma heated exothermically, at least from one reaction zone, to a partial vacuum in a chamber separated from said zone, at a pressure lower than the water vapor tension in the heated magma, to effect the evaporation of water and thus reduce the temperature, and return the cooled and concentrated magma to one or more reaction zones, to regulate the temperature in them.
