Abstract
La présente invention est relative à la fabrication d'acide phosphorique par voie humide de concentration moyenne (26 à 30 % P2O5) à partir du phosphate naturel et de l'acide sulfurique. Elle concerne une amélioration à la fois du dispositif réactionnel permettant de pousser le taux de solubilisation de la roche phosphaté à des valeurs supérieurs et d'assurer une meilleure cristallisation du gypse produit, ainsi que du mode de filtration permettant d'améliorer la filtrabilité de la bouillie et de produire un acide phosphorique plus concentré.
