摘　　要：针对高碱性难处理氧化锌矿采用常规氨浸浸出率低的问题,采用超声波强化其浸出过程,结果表明超声波强化浸出氧化锌矿有利于提高锌的浸出率,最佳浸出条件为超声波功率550 W、浸出剂浓度5 mol/L、浸出体系液固比9:1、浸出过程超声波作用时间1.5 h和浸出温度为45℃,浸出率达93.80%,锌的浸出率比无超声波作用时高出10%以上,且在相同浸出条件下,超声波强化浸出可大幅缩短浸出时间和降低浸出反应温度。为难处理氧化锌矿浸提工艺的改进提供了新的思路。In view of the low leaching rate of high alkaline refractory zinc oxide ore by conventional ammonia leaching,the ultrasonic wave enhanced leaching process.The results showed that ultrasonic wave enhanced leaching of zinc oxide ore is beneficial to improve the zinc leaching rate.The optimum leaching conditions with respect to ultrasonic wave power,leaching agent concentration,leaching system liquid-solid ratio,ultrasonic wave time and leaching temperature were found to be 550 W,5 mol/L,9:1,1.5 h and 45℃,respectively,the leaching rate reaches 93.80%.The zinc leaching rate is more than 10% higher than that without ultrasonic wave treatment.Under the same leaching conditions,ultrasonic wave enhanced leaching can greatly shorten the leaching time and reduce the leaching reaction temperature.It provides a new idea for improving the extraction process of refractory zinc oxide ore.
