| Abstract: |
| 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%. |
