| Abstract: | A technology of iron removal from acid removal from acid leaching liquid of zinc blende has been studied. The acid leaching liquid is filtered andcontrolled in the rage 1.5～2.0. Prelimary iron-removal from the acid leaching liquid can be achieved using the method for producing jarosite under the following conditions: temperatare of above 90 ℃, addition of a few activated carbon and oxygen and reaetion time of 4 hrs. Jarosite is separated by filtration. At 80～85 ℃ and pH=4, further iron-removal can be achieved by adding hydrogen peroxide to the liquid. After reaction for 4 hrs, the iron-removal rate is 99% and the content of iron in the final solntion is below 0.01 g/L. |
| Keywords: | zinc blende zinc sulfate hydrogen peroxide iron removal |
