Abstract

En un método para recuperar un concentrado de sulfuro de cobre mediante flotación por espuma de una mena que contiene un sulfuro de hierro, se añade peróxido de hidrógeno a la pulpa mineral acondicionada antes de o durante la flotación, se determina la concentración de oxígeno disuelto en la pulpa mineral tras la adición de peróxido de hidrógeno y se ajusta la cantidad de peróxido de hidrógeno añadido para mantener una concentración de oxígeno disuelto de desde 1 hasta 5 veces una concentración ...
