  • MEI Blog: Challenges in copper flotation Barry A. Wills

    Sep 17, 2011· Flotation of difficulttofloat copper porphyry ores indicates that the primary reasons for the problems are mineralogical diversity, metallurgical factors, and process limitations. A detailed analysis of these factors indicates that, most often, difficulties in the flotation of copper porphyry ores arise due to mineralogy and metallurgy interrelated factors.
