| Abstract: | The technology of iron removal in the production of zinc sulfate by oxygen oxidizing following with deep oxidization of H2O2 has been studied. The suitable conditions are as following:with oxygen oxidizing, pH4～5,temperature 85～90℃,reaction time 2～3h; with oxidization of H2O2, pH3～4, temperature 80～85℃, reaction time 3～4h, the dosage of H2O2～3g/L.Under the above conditions,the content of ferric ions in acidic leaching liquid can be decreased below 0.01 g/L. Comparing with other method,this method has the advantages of easy conytrol and better effectiveness of iron removal |
