Abstract
Procesos para recuperar molibdeno y/u otros metales valiosos (por ejemplo, uranio) presentes en soluciones acuosas de un gran rango de concentraciones: de ppm a gramos por litro por medio de un proceso de extraccion de solvente extrayendo el molibdeno y/u otro metal valioso de la solucion acuosa poniéndola en contacto con una solucion en fase orgánica que contiene un ácido fosfínico, destilando el molibdeno y/u otro metal valioso de la solucion en fase orgánica poniéndola en contacto con una solucion de destilacion en fase acuosa que contiene un compuesto inorgánico y que tiene una concentracion de 1,0 M de amoníaco libre y recuperando el molibdeno u otro metal valioso separándolo de la solucion de destilacion en fase acuosa. Cuando el molibdeno y/u otro metal valioso están presentes solo en baja concentracion, los procesos pueden incluir una etapa de reciclado de fase orgánica y/o una etapa de reciclado de destilacion en fase orgánica a fin de concentrar el metal antes de la recuperacion. Reivindicacion 1: Un proceso para recuperar molibdeno de una solucion acuosa ácida que contiene molibdeno, que comprende: a) poner en contacto la solucion acuosa con una solucion en fase orgánica que comprende un ácido fosfínico, extrayendo en este caso al menos parte del molibdeno de la fase acuosa a la fase orgánica; b) poner en contacto la fase orgánica con una solucion de destilacion en fase acuosa que comprende un compuesto inorgánico y que tiene un pH de 5 a 11 destilando en este caso al menos parte del molibdeno de la fase orgánica a la solucion de destilacion en fase acuosa, siempre que, cuando el compuesto inorgánico es NH4OH, la concentracion de amoníaco libre es de 0,01 a 1,0 M; y c) separar el molibdeno de la solucion de destilacion en fase acuosa, recuperando así el molibdeno.
