摘　　要：采用加压酸浸工艺从含锗氧化锌烟尘中高效浸出锗、锌,研究了浸出温度、浸出时间、氧气压力、硫酸用量及液固体积质量比对锗、锌浸出率的影响。结果表明,在硫酸用量为理论量的1.5倍、液固体积质量比为3mL/g、浸出时间为3.0h、浸出温度为80℃、氧气压力为800kPa、搅拌速度为500r/min的条件下,锗、锌的浸出率分别可达75.11%、97.21%。The zinc oxide dust bearing germanium was treated by pressure leaching process for high-efficient leaching of germanium and zinc. The effects of leaching temperature, leaching time, oxygen pressure, sulfuric acid amount, and liquid-solid volume-mass ratio on the leaching rate of germanium and zinc were studied. The experimental results show when sulfuric acid amount is 1.5 times of the theoretical quantity, liquid-solid volume-mass ratio is 3 mL/g, pressure leaching time is 3.0 h, leaching temperature is 80 ℃, oxygen pressure is 800 kPa, stirring speed is 500 r/min, the germanium and zinc leaching rate can reach 75.11% and 97.21%, respectively.
