Abstract
La presente invención se refiere a un método para preparar ácido fosfórico y sulfato de calcio como subproducto, caracterizado porque, en una mezcla que contiene sulfato de calico, que fluye a través de una secuencia de zonas de reacción, se somete fosfato de calcio a ataque por una mezcla de ácidos sulfúrico y fosfórico, y al menos parte del ácido fosfórico producido se retira, y porque comprende ajustar los caudales de flujo de la mezcla circulante con respecto al caudal de flujo de base de la mezcla, que corresponde al caudal de flujo que está siendo descargado de las zonas de reacción.
