Abstract
PROCEDIMIENTO PARA LA RECUPERACION DE COMPUESTOS DE URANIO, CUANDO ESTAS SOLUCIONES CONTIENEN NITRATO AMONICO Y TAMBIEN OXIDO NITRICO. EN PRIMER LUGAR SE APLICA EL PROCEDIMIENTO DE SEPARACION DE LA PATENTE PRINCIPAL PARA EL ANHIDRIDO CARBONICO, AMONIACO Y AGUA. UNA VEZ HECHO ESTO LA SOLUCION RESTANTE SE EVACUA EN UN DEPOSITO DE CRISTALIZACION CON CRISTALES DEL PRODUCTO DE PRECIPITACION, MANTENIENDOSE ENTRE 50 Y 55GC. SE DOSIFICAN CONSECUTIVAMENTE (I) Y (II) MANTENIENDO EL PH ENTRE 5,6 Y 5,9 MEDIANTE ADICION REGULADA DE (III). A CONTINUACION SE ALMACENA EL COMPUESTO DE ADICION PRECIPITADO. ESTE CONTIENE MENOS DE 20 MG./L DE PEROXIDO DE URANIO Y NITRATO AMONICO, PUDIENDO CONTENER TAMBIEN PRODUCTOS SUBSIGUIENTES DE LA DESCOMPOSICION DE URANIO. (I) HNO3; (II) H2O2; (III) HN3.
