| 摘 要： | 对云南某地富锗硫化锌精矿进行了氧压酸浸回收锗的试验研究。通过正交试验,研究了浸出温度、浸出时间、氧分压、精矿粒度、酸锌摩尔比和搅拌速度对锗浸出率的影响。结果表明,浸出温度和氧分压是影响锗浸出率的主要因素,在试验选定的条件下,锌和锗的浸出率能达到99%和90%以上。

| Abstract: | Lab-scale pressure oxidative leaching experiments of germanium-rich zinc sulphides were carried out,to investigate the variables such as leaching temperature,leaching duration,oxygen pressure,granularity,molar ratio of acid to zinc and rotation speed on the dissolution of germanium.Orthogonal experiment results showed that leaching temperature and oxygen pressure are major factors affecting the dissolution of germanium.In the optimum conditions,the dissolution rate of zinc and germanium could reach more than 99% and 90% respectively. |

| Keywords: | zinc sulphides concentrate pressure oxidative dissolution germanium zinc dissolution |
