硫化铵提取铅渣中硫工艺条件的研究

Study on the Process Conditions Extraction of Sulphur from Lead Slag Using Ammonium sulfide

研究硫化铵浸取单质硫,探求铅渣中提取硫最佳工艺条件。结果表明:硫化铵浸取单质硫最佳工艺条件是液固比为3∶1,硫化铵溶液浓度为140g/L,硫与硫化铵的摩尔比为1∶0.4,浸出时间为25min,硫的浸出率达到98%。

To study leaching of sulfur using ammonium sulphate,and explore the optimum process conditions of extracting sulfur from lead slag.The results showed that the optimum conditions were liquid to solid ratio was 3∶1,concentration of ammonium sulphate was 140 g/L,molar ratio of sulfur and ammonium sulfide was 1∶0.4,leaching time was 25 minutes.
