Chalcopyrite is the resource with highest amount of Cu content representing around 70–80% known reserves in world. However, chalcopyrite like other copper sulfides, usually found deposits grades 0.4–0.5% copper. The exploitation these using traditional flotation methods followed by pyrometallurgical treatment concentrate at limit economic viability. Hydrometallurgical route would be more suitab...

Fe isotopes have been applied to the petrogenesis of ore deposits. However, behavior iron in mineralization porphyry-skarn deposits is still poorly understood. In this study, we report mineral separations (magnetite, pyrite, chalcopyrite and pyrrhotite) from two different skarn deposits, i.e., Tonglvshan Cu-Fe deposit developed an oxidized hydrothermal system Anqing Cu a reduced system. both ca...
