Abstract

PROCEDIMIENTO DE RECUPERACION DEL URANIO PRESENTE EN UNA DISOLUCION DE ACIDO FOSFORICO. CONSTA DE LAS SIGUIENTES ETAPAS: 1. EXTRACCION DEL URANIO POR PUESTA EN CONTACTO DE LA SOLUCION CON UN COMPUESTO ORGANOFOSFORADO ACIDO Y POR UN ACIDO NEUTRO DE FOSFINA. 2. REEXTRACCION PONIENDO A CONTRACORRIENTE DEL DISOLVENTE ORGANICO UNA SOLUCION DE CARBONO DE AMONIO, TRANSFORMANDOSE EL URANIO PRESENTE EN URANIL TRICARBONATO DE AMONIO; ADEMAS SE AÑADE AMONIACO PARA MANTENER EL PH ENTRE 8 Y 8,5. EL DISOLVENTE ORGANICO AMONIACO DE LA REEXTRACCION SE PURIFICA HACIENDOLO REACCIONAR CON UN ACILO, CON LO QUE SE REUTILIZA.
