Abstract

Proceso para recuperar molibdato o tungstato de una solución acuosa, por el cual el molibdato o el tungstato provenientes de la solución acuosa se unen a un material de vehículo inorgánico isoluble en agua, cationizado, a un pH dentro del rango entre 2 y 6. El material de vehículo cargado se separa y el molibdato o el tungstato unidos se liberan una vez más en una solución acuosa a un pH dentro del rango entre 6 y 14.
