dc.description.abstract	The dissolution kinetics of the primary calcined chalcopyrite ore from Damar mine area in Artvin city, Turkey was investigated in sulphuric acid solution. The ore was calcined for 1, 2 and 3 h at 373, 473, 573,....1273 K temperatures. Then the calcined samples were dissolved in sulphuric acid solution. The calcination temperature and time, sulphuric acid concentration, solid/liquid ratio, agitation rate, particle size, dissolution temperature and time were determined. In addition the sulphation of the sulphide ore between 573-1073 K temperatures was examined. Finally, the activation energy in the dissolution was calculated as 4.04 kJ/mole for the calcined chalcopyrite ore. It was found that the dissolution process was controlled by limit film diffusion.
