| 摘 要： | 氧化锌矿资源化利用是当前锌冶炼行业重要关注点。通过超声波辅助和常规机械搅拌碱浸处理氧化锌矿对比实验，考查实验因素温度、时间、初始碱浓度、超声波功率/搅拌速率等对锌浸出率的影响。结果表明，超声波辅助浸出效果优于常规浸出，在较优实验参数超声波功率400 W、温度65℃、时间40 min、初始碱浓度4 mol/L、液固比10∶1下重复实验，Zn平均浸出率为91.62%。超声波辅助浸出可大幅缩短反应时间。超声波在浸出提取锌的过程中发挥重要作用。

| Abstract: | Resource recycling of Zinc oxide ore is an important concern in zinc smelting industry at present. In this study, comparison of ultrasonic-assisted and traditional treatment of zinc oxide ore with caustic leaching process was investigated. Effects of experimental factors temperature, time, initial alkali concentration, ultrasonic power, and agitation rate, on zinc leaching rate, were examined. Results showed that zinc leaching rate of ultrasonic assisted process was better than that of traditional process. The optimal parameters were ultrasonic power of 400 W, temperature of 65℃, time of 40 min, initial alkali concentration of 4 mol/L, and liquid to solid ratio of 10∶1, and the average leaching rate of zinc under optimal conditions was 91.62%. Ultrasonic-assisted leaching can shorten the reaction time greatly. Ultrasonic played a notable effect in zinc oxide ore leaching process. |
