  • Sulfide Oresan overviewScienceDirect Topics

    Copper sulfide ores must be concentrated before they can be economically transported and smelted. The universal technique for this concentration is froth flotation of finely ground ore. Froth flotation entails attaching fine Cusulfide mineral particles to bubbles and floating them out of a waterore mixture.
