| Abstract | The sulfuric acid leaching of electric arc furnace(EAF) dust was studied in an attempt to find a suitable hydrometallurgical method for the recovery of zinc. The effect of acid concentration, reaction temperature, stirring rate and solid-to-liquid ratio on Zn and Fe extraction from the solution was investigated. It was found that the leaching rate of Zn and Fe increased with increasing reaction temperature and sulfuric-acid concentration. Examination of data using a shrinking core model suggest that the leaching rate is controlled by mixture kinetics. The activation energy for the leaching reaction of Zn and Fe were calculated as 44.45 kJ/mol and 65.45 kJ/mol, respectively. |
