| Abstract: | Study on lab-scale pressure oxidative acid leaching test for a complex low-grade zinc sulphide ore in Yunnan was carried out, which the influences of the leaching temperature, time, oxygen partial pressure have been investigated. The test results showed that the zinc leaching rate can be above 97.5%, the terminal acidity and the iron concentration can be respectively controlled around 15.0g/L and under 5g/L under the optimized test condition. |
