Abstract

"Procedure for manufacturing phosphoric acid by wet route", characterized in that in a first phase, starting from natural phosphate and sulfuric acid and within the porridge that has already reacted, the attack of most of the phosphate is carried out in conditions of concentration and temperature that lead to the formation of gypsum, by an amount of sulfuric acid greater than the amount necessary for the reaction; they are transferred to a second reaction phase containing the slurry that has already reacted at least a part of the results of the reaction of the first phase and an additional amount of phosphate is introduced there and this additional amount reacts with gypsum formation, and separates the produced phosphoric acid.
