project proposal for extraction of copper from chalcopyrite ore
Chalcopyrite – WGNHS – UW–Madison
ResultChalcopyrite is an important ore of copper found in a wide range of hydrothermal environments. It is often associated with sphalerite and galena. It oxidizes to form copper minerals such as malachite, azurite, cuprite and tenorite. Copper liberated from the breakdown of chalcopyrite may accumulate in secondary supergene …
