Abstract
METODO DE RECUPERACION DE URANIO EN DOS CICLOS A PARTIR DE DISOLUCION ACUOSA DE ACIDO FOSFORICO. EL PRIMER CICLO SE ALIMENTA CON UNA SOLUCION ACUOSA DE ACIDO FOSFORICO, PH ENTRE 0,1 Y 2,5, QUE CONTIENE IONES URANILO OXIDADOS EN PROPORCION DE 0,1 G/L A 0,5 G/L DE URANIO, 600 G/L DE FOSFATO Y ENTRE 3 G/L Y 15 G/L DE HIERRO. LA SOLUCION QUE INICIA EL SEGUNDO CICLO ES SIMILAR A LA ANTERIOR PERO CONTIENE ENTRE 3 G/L Y 15 G/L DE URANIO Y DE 25 G/L A 40 G/L DE HIERRO. LA EXTRACCION DE LA DISOLUCION DE ACIDO FOSFORICO SE REALIZA CON UN DISOLVENTE QUE CONSTA DE ACIDO DI-2-ETILHEXILFOSFORICO Y OXIDO DE TRI-N-OCTILFOSFINA EN QUEROSENO; SEGUIDA DE UNA SEGUNDA SEPARACIOIN CON EL DISOLVENTE DESPUES DE HABER ELIMINADO DEL MISMO EL ACIDO FOSFORICO ARRASTRADO, POR TRATAMIENTO CON UNA DISOLUCION ACUOSA DILUIDA DE ACIDO SULFURICO O ACIDO NITRICO DE 2 A 10% EN VOLUMEN, QUE MANTIENE EL PH DEL DISOLVENTE EN UN VALOR COMPRENDIDO ENTRE 3 Y 6,5. FINALMENTE, SE SEPARAN LOS COMPUESTOS DE URANIO CON UNA DISOLUCION ACUOSA DE CARBONATO AMONICO Y/O BICARBONATO AMONICO.
