| 摘 要： | 针对富铼渣中成分多、金属赋存状态复杂的特点，采用控电位氧化浸出方法对富铼渣中的铼进行浸出试验，通过单因素试验确定了下述最优条件：氧化浸出电位700~750 mV、硫酸质量浓度15%、浸出温度70 ℃、浸出时间60 min，在此条件下铼浸出率为98.612%，其他组分浸出率均高于90%。

| Abstract: | Address to the characteristics of high composition and complex metal occurrence in rhenium-rich slag, a controlled potential oxidation leaching method was used to conduct leaching experiments on rhenium in rhenium-rich slag. Through single factor experiments, the optimal experimental conditions are determined as follow: oxidation leaching potential of 700—750 mV, mass concentration of sulfuric acid of 15%, leaching temperature of 70 ℃, and leaching time of 60 minutes. Under these conditions, the leaching rate of rhenium is 98.612%, and the leaching rate of other components is 90% above. |
