The leaching of zinc and germanium from germanium-rich zinc concentrate by oxygen pressure leaching process was studied. The effects of key factors such as the initial acidity of sulfuric acid, reaction temperature, leaching time, oxygen partial pressure, sodium lignosulfonate addition amount, liquid volume to solid mass ratio, and stirring speed on the leaching rates of zinc and germanium were systematically investigated. The optimal process conditions for oxygen pressure leaching are determined through single-factor experiments as follows:leaching temperature is 160 ℃, leaching time is 150 min, initial acidity of sulfuric acid is 160 g/L, partial pressure of oxygen is 1.2 MPa, addition amount of sodium lignosulfonate is 1 g, liquid volume to solid mass ratio is 8/1, and stirring speed is 600 r/min. Under the conditions, the germanium leaching rate reaches 94.86% and the zinc leaching rate reaches 99.98%. Compared with the traditional atmospheric pressure leaching, the optimized oxygen pressure process can increase the germanium leaching rate by more than 15%, shorten the leaching time by 40%, and also avoid the emission of high-concentration H₂S gas, reducing environmental pollution and providing a technical reference for the comprehensive utilization of valuable elements in zinc concentrate.

研究了采用氧压浸出工艺从富锗锌精矿中浸出锌、锗，系统考察了硫酸初始酸度、反应温度、浸出时间、氧分压、木质素磺酸钠添加量、液固体积质量比、搅拌速度等关键因素对锌、锗浸出率的影响。通过单因素试验优化确定氧压浸出最佳工艺条件为：浸出温度160 ℃、浸出时间150 min、硫酸初始酸度160 g/L、氧分压1.2 MPa、木质素磺酸钠添加量1 g、液固体积质量比8/1、搅拌速度600 r/min，该条件下锗浸出率达94.86%，锌浸出率达99.98%。与传统常压浸出相比，优化后的氧压工艺锗浸出率可提升15%以上，浸出时间缩短40%，还可避免高浓度H₂S气体排放，减少对环境的污染，可为实现锌精矿中有价元素的综合利用提供技术参考。
