Abstract

Procedimiento para la obtención de compuestos de uranio de gran pureza, por ataque sulfúrico de un mineral o de un concentrado uranífero seguido por la separación de las fracciones no disueltas y del licor L1 resultante del ataque, caracterizado porque se elimina la mayor parte de las impurezas presentes en L1 llevando éste a un valor de la relación agua/ácido libre E/A, comprendida entre 0,16 y 0,26 y eliminando el precipitado S2 formado, y a continuación se diluye la fase líquida restante L2 hasta un valor E/A comprendido entre 0,35 y 0,50 y se recupera el precipitado S3 así obtenido.
