Abstract

En una deslignificación de pulpa con peróxido de hidrógeno catalizada por molibdato, el molibdato se puede recuperar poniendo en contacto la solución acuosa que contiene molibdato a un pH en el rango de 2 a 7 con un material portador que comprende un silicato estratificado intercambiado iónicamente con una sal de amonio cuaternario y posterior flotación sin un tensioactivo que tiene que ser añadido por flotación.
