Abstract

PROCEDIMIENTO DE RECUPERACION DEL URANIO CONTENIDO EN UNA DISOLUCION EN ACIDO FOSFORICO. CONSTA DE LAS SIGUIENTES OPERACIONES: 1. EXTRACCION DEL URANIO POR CONTACTO ENTRE LA DISOLUCION QUE LO CONTIENE Y UN DISOLVENTE ORGANICO FORMADO POR UN COMPUESTO ORGANOFOSFORADO ACIDO Y POR UN OXIDO NEUTRO DE FOSFINA; EL TIEMPO DE CONTACTO ES INFERIOR A 5 MINUTOS. 2. REEXTRACCION DEL URANIO PRESENTE EN EL DISOLVENTE PONIENDO EN CONTACTO EL DISOLVENTE ORGANICO CON UNA DISOLUCION ACUOSA DE ACIDO FOSFORICO CON UNA CONCENTRACION SUPERIOR A 10 M; EL ACIDO FOSFORICO DEBE CONTENER UN AGENTE REDUCTOR CONSTITUIDO POR HIDRAZINA, IONES FERROSOS O SUS MEZCLAS.
