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最优条件为氧化浸出电位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%。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.
