Abstract
Procedimiento para la recuperación de compuestos de uranio de las soluciones de carbonato amónico y soluciones de hidrogenoflururo amónico así como aguas residuales que contienen flúor, especialmente de los filtrados que contienen uranio, que se forman en la así llama conversión auc en el curso de la obtención de combustible nuclear UO2'' caracterizado porque la solución de partida se calienta en una sola pasada a través de un calentador de paso eléctrico hasta a unos 95ºc, de esta manera se libera CO2 hasta a 6g/1 y NH3 y de la solución que queda, bajo alimentación de NH3, aire y H202 a una temperatura de 50-55º y acelerado por la presencia de cristalería de inyección se precipitan los compuestos de uranio y2 NH4f.UO4) hasta < 10 mg/l en la solución residual y a continuación se oxidan en un horno a 800 ºC mediante vapor de agua a U3O8 libre de flúor.
