Abstract

La presente invención reivindica un proceso para la recuperación de molibdeno grado técnico a partir de soluciones ácidas diluidas de lixiviación (PLS), altamente concentradas en arsénico, donde el proceso comprende las etapas de: (a) poner en contacto una solución acida de lixiviación (PLS) previamente filtrada proveniente de la lixiviación de los polvos de fundición con una resina aniónica de intercambio iónico; (b) lavar con agua la resina cargada; (c) extraer el molibdeno de la resina de intercambio iónico con una solución regenerante alcalina de amonio a un valor de p H entre 8 y 12, para formar molibdato de amonio en solución; (d) lavar con agua la resina descargada; (e) agregar sales de magnesio y/o hierro a la solución amoniacal recuperada, para obtener un precipitado el cual es llevado a la etapa de abatimiento de arsénico, y una solución que contiene el molibdato de amonio en solución; (f) agregar ácido sulfúrico a la solución amoniacal libre de arsénico, para precipitar el molibdeno en la forma de molibdato de amonio en ambiente ácido a un valor de p H entre 1,5 y 4; (g) separar el precipitado formado mediante filtración del molibdato y recircular la solución obtenida a la solución inicial de PLS; (h) calcinar el precipitado separado para obtener trióxido de molibdeno y amoniaco; y (i) recuperar el amoniaco desprendido para su posterior retorno al proceso como solución regenerante recirculada.
