摘　　要：采用常压-加压联合浸出工艺从含锗氧化锌烟尘中高效浸出锌、锗,研究了浸出时间和温度、硫酸用量、液固比等对锌、锗浸出率的影响。结果表明,在最佳工艺条件下,锌、锗浸出率分别为96.92%、89.72%。Zinc oxide dust bearing germanium was treated by atmospheric-pressure leaching process for high-efficient leaching of zinc and germanium.The effects of leaching temperature and time,sulfuric acid dosage,and ratio of liquid to solid on leaching rates of zinc and germanium were studied.The experimental results show that under condition of the optimum process parameters,zinc and germanium leaching rates can reach 96.92% and 89.72%,respectively.
