Leaching of sulfidized chalcopyrite with H(2)SO(4)-NaCl-O(2)
|
The recovery of copper from chalcopyrite by leaching is complex not only due to the slow dissolution kinetics of this mineral in most aqueous media but also due to the production of solutions that are heavily contaminated with iron. On the contrary, the leaching of sulfidized chalcopyrite is very attractive because of a faster and more selective dissolution of copper compared to the leaching of the untreated chalcopyrite. In this work, the results of leaching in H^sub 2^SO^sub 4^-NaCl-O^sub 2^ solutions of sulfidized chalcopyrite concentrate are discussed. Experiments were carried out with ...
