Abstract

El proceso de la presente invención incluye obtener un material de alimentación que tiene un tamaño de partículas mediano inicial. Se forma una solución de un dispersante de policarboxilato en agua, después el material de alimentación se agrega a la solución para formar un fango. El fango se tritura o muele por vía húmeda para reducir el tamaño de partículas mediano del material de alimentación. Opcionalmente, la cantidad total de dispersante de policarboxilato se divide en una pluralidad de dosis que se agregan periódicamente durante el tiempo de trituración total.
