Abstract

In this research, CHLORINATION of CHALCOPYRITE in a high-energy mill was carried out in order to convert CHALCOPYRITE to COPPER CHLORIDE. CHALCOPYRITE milling was performed at ambient temperature and dry CHLORINE gas atmosphere, in time rang 30 to 120 minutes and ball to powder weight ratio 10 and 20. X-ray diffraction analysis was used to identify the phases formed in the samples. X-ray diffraction pattern of milled CHALCOPYRITE powders showed that in the high-energy milling, after a specified time, CHALCOPYRITE is converted to chloride of iron, copper and sulfur. Scanning electron microscope images were obtained to evaluate the products morphology and reaction kinetics. Eventually, milling time of 100 minutes with a ball to powder ratio of 20 was obtained as the optimum conditions. Kinetic analysis also indicated that the process is controlled by chemical reaction.
