dc.description.abstractIn this work, the leaching of malachite, an oxidized copper ore, in ammonia/ammonium chloride solution was studied. The effects of the reaction temperature, ammonia and ammonium chloride concentration, and stirring speed on the leaching of malachite were examined. According to findings obtained, it was determined that ammonia/ammonium chloride ratio has a considerable effect on the dissolution of ore. It was observed that the dissolution rate increased with increasing temperature, and the stirring speed has not a considerable effect. The kinetic analysis of the leaching process was performed by applying the heterogeneous reaction models, and it was found that the leaching reaction followed the mixed kinetic controlled model. It was determined that the leaching reaction was controlled by diffusion at low temperatures, while it was controlled by chemical reaction at high temperatures. The activation energies for two consecutive mechanisms were calculated to be 19.5 and 50.8 kJ/mol, respectively.en_US
