摘　　要：　用硫酸和氧气及催化剂对陕西某地的硫化锌精矿进行了浸出试验研究。详细考察了硫酸和催化剂的用量、浸出温度、浸出时间、液固质量比、搅拌速度等因素对浸出率的影响。试验结果表明:在适宜的工艺条件下,锌的浸出率可达到97%以上。硫以单质硫析出,回收率90%以上。The test of leaching rate on zinc sulfide concentrate in Shaanxi province with sulfuric acid, oxygen and catalyst has been taken. The effecting factors such as consumption of sulfuric acid, catalyst, temperate, time, ratio of liquid to solid, and stir speed on leaching rate has been studied in detail. The results show that the zinc leaching rate may reach 97% on optimum conditions, the sulphur element can be recovered in the form of S, and the S recovery is more than 90%.
