Abstract

La presente invencion se refiere a un procedimiento de preparacion de monohidrogenofosfato de calcio que comprende un ataque quimico en medio acuoso, durante un periodo de tiempo predeterminado, de una fuente de fosfato mediante un acido con formacion de una pulpa que comprende una fase acuosa que contiene el fosfato de calcio en solucion y una fase solida que contiene impurezas, una primera separacion entre dicha fase acuosa y dicha fase solida, durante un periodo de tiempo predeterminado, una neutralizacion de dicha fase acuosa a un pH suficiente para obtener una precipitacion de dicho monohidrogenofostato de calcio, una segunda separacion entre dicho medio acuoso y dicho monohidrogenofosfato de calcio, caracterizado porque dicha primera separacion de dicha etapa b) se realiza a una velocidad de filtracion de al menos 0,1 toneladas de P2O5/Raiz delta P/m2/dia.
