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 agrega peróxido de hidrógeno a la pulpa de mineral acondicionada antes o durante la flotación en una cantidad eficaz para reducir el potencial redox de la pulpa de mineral acondicionada a fin de mejorar la ley de concentrado y la recuperación de sulfuros de cobre.
