Abstract
Procedimiento para recuperar el uranio presente en compuestos fosfatados, por medio de una fase orgánica que contiene un ácido dialquilo pirofosfórico, caracterizado porque la fase orgánica contiene además al menos un mol de un agente de solubilización del alquilo pirofosfato doble de uranio y de amonio por mol de ácido dialquilo pirofosfórico y porque comprende las etapas siguientes: a) se hace burbujear en la fase orgánica previamente cargada en uranio, amoniaco anhidro para precipitar la sal de amonio del ácido dialquilo pirofosfórico en exceso; b) se realiza una separación líquido-sólido para separar de la fase orgánica la sal de amonio del ácido dialquilo pirofosfórico precipitado en la etapa a).
