Abstract
Procedimiento de ataque del mineral de fosfato, que comprende: - una digestión del mineral de fosfato por una solución acuosa de ácido clorhídrico, con formación de un licor de ataque constituida de una fase acuosa, en la que el fosfato de calcio está en disolución, y de una fase sólida insoluble, que contiene impurezas, - una primera separación entre la fase sólida insoluble y la fase acuosa del licor de ataque, - una neutralización previa de un medio acuoso que contiene fosfato de calcio en solución a un primer pH inferior al pH al que una parte significativa de este fosfato de calcio en disolución precipita en forma de monohidrogenofosfato de calcio (DCP), con precipitación de impurezas, - un aislamiento de las impurezas precipitadas a partir del medio acuoso previamente neutralizado, - una neutralización ulterior de dicho medio acuoso previamente neutralizado a un segundo pH superior a dicho primer pH, con precipitación de DCP, y - una segunda separación entre el medio acuoso ulteriormente neutralizado, que es una solución acuosa de cloruro de calcio, y DCP precipitado. caracterizado por que comprende una digestión, en una etapa y en sentido paralelo, de mineral de fosfato que presenta un contenido en P2O5 superior al 20% en peso por una solución acuosa de ácido clorhídrico que presenta una concentración de HCl inferior al 10% en peso y por que, para alcanzar dicho primer pH, dicha neutralización previa se efectúa antes de dicha primera separación en dicho licor de ataque como medio acuoso que contiene fosfato de calcio en solución, teniendo lugar el aislamiento de las impurezas precipitadas durante dicha primera separación de dicha fase sólida insoluble, y siendo dicho medio acuoso previamente neutralizado y sometido a dicha neutralización ulterior formado de la fase acuosa separada, procedente de la primera separación.
