Abstract

Procedimiento para la recuperación del uranio contenido en soluciones fosfatadas, caracterizado porque comprende las siguientes etapas: a) puesta en contacto de la solución fosfatada uranífera de partida con una fase orgánica que contiene un diéster del ácido pirofosfórico; b) puesta en contacto con una solución alcalina de la fase orgánica cargada en uranio obtenida en la etapa a) anterior; c) adición a la solución alcalina de un agente de precipitación del uranio; d) acidificación del producto resultante de la etapa c) anterior; e) agitación y después separación de la fase orgánica de la fase acuosa; f) reciclado de la fase orgánica con la etapa a) de puesta en contacto; siendo además efectuada una operación de separación sólido-líquido entre la etapa c) de adición de un agente de precipitación del uranio y la etapa f) de reciclado.
