Abstract
Procedimiento con su instalación de realización para fabricar ácido fosfórico por vía húmeda, que comprende la reacción de ataque de un mineral de fosfato con ácido sulfúrico, la cristalización del sulfato de calcio así obtenido, la separación de esto último por filtración y lavado con agua, y el reciclado, hacia dicho ataque, a título de reactivo auxiliar de ataque, de una parte de los filtrados resultantes de esta separación y de este lavado, constituyendo la parte restante de estos filtrados el ácido fosfórico producido, según el cual procedimiento la reacción se efectúa en una pasta acuosa de reacción que contiene ácido fosfórico y sulfato de calcio resultante de las reacciones y cristalizaciones anteriores, hallándose inclusa esta pasta de reacción en una sucesión de zonas de reacción en cada una de las cuales se mantiene una circulación local de la pasta, los reactivos, esto es el mineral de fosfato, el ácido sulfúrico y la parte reciclada de los mencionados filtrados, siendo introducidos en una o varias de estas zonas, mientras que se extrae, a partir de una de las zonas de reacción.
