Dissolution of copper from a primary chalcopyrite ore supplied from Damar mine area in Murgul-Artvin, Turkey, has been investigated in sulphuric acid solution after the calcination with and without Fe₂O₃. The chalcopyrite with and without Fe₂O₃ were performed by thermogravimetric (TG) analysis, and the calcined chalcopyrite samples were characterized by X-ray diffraction (XRD). In the leaching experiments, the effects of calcination temperature, sulphuric acid concentration, solid/liquid ratio, agitation rate, particle size and dissolution temperature and time on copper dissolution were examined. It was found that Fe₂O₃ addition contributed to sulphation during the calcination and then copper dissolution.
