Abstract

Un método de purificación de sustancias que contienen uranio que contienen compuestos de uno o más de los metales aluminio, magnesio, calcio y hierro por separación del uranio de dichas sustancias, efectuándose dicha purificación por lixiviación alcalina selectiva con carbonato del uranio, en el que la sustancia se divide finamente y se pone en suspensión en una solución acuosa que contiene 0,3-1,5 moles/litro de iones carbonato y que tiene un potencial de oxidación de 0,3-1 V, y en el que, subsiguientemente al procedimiento de lixiviación, el líquido de lixiviación tiene un pH comprendido entre 8,5 y 10,5 a presión de 0,2 a 2,0 MPa.
