Abstract

Se refiere a un metodo para recuperar un concentrado de sulfuro de cobre mediante flotacion por espuma de una mena que contiene un sulfuro de hierro, se anade peroxido de hidrogeno a la pulpa mineral acondicionada antes de o durante la flotacion, se determina la concentracion de oxigeno disuelto en la pulpa mineral tras la adicion de peroxido de hidrogeno y se ajusta la cantidad de peroxido de hidrogeno anadido para mantener una concentracion de oxigeno disuelto de desde 1 hasta 5 veces una concentracion objetivo predeterminada, para ajustar la cantidad de peroxido de hidrogeno frente a cambios en la composicion de la mena
