Processing of chalcopyrite ore by heap leaching and flotation

In conventional mineral processing, a portion of the copper metal value is inevitably lost to flotation tailings and not recovered as concentrate. That portion of metal value lost to tailings is determined partially by the mineral characteristics of the chalcopyrite, such as grain size and liberation (Wills, 1992).
