摘要
In a method for recovering a copper sulfide concentrate by froth flotation from an ore containing an iron sulfide, hydrogen peroxide is added to the conditioned mineral pulp before or during flotation in an amount effective to lower the redox potential of the conditioned mineral pulp in order to improve concentrate grade and recovery of copper sulfides.
