%X The process for conventional leaching of slag containing antimony and lead in HCl-NaCl solution was investigated. Under the optimum conditions of the leaching process, ultrasonic was used to strengthen the process. The results showed that the leaching rate of antimony was strengthened by ultrasonic for 15 min, equal to that of the conventional leaching for 45 min. Ultrasonic could increase the leaching speed of antimony and lead evidently, and the leaching time was decreased. The leaching rate of antimony and lead was increased with the increase of ultrasonic power. When the leaching rate reached the same value, the leaching time of the process strengthened by high power ultrasonic was shorter than that of low power ultrasonic. The maximum leaching rate of antimony and lead was limited by the fixed phase composition of the slag, and the energy of ultrasonic can not produce a new pathway for the reaction which can not occur under the conventional conditions. However the maximum leaching rate of Sb and Pb has nothing to do with the using of ultrasonic.
