| 摘 要： | 采用硫代硫酸钠为含铼污酸的沉淀剂,考察了硫代硫酸钠用量、反应时间和温度对铼和铜沉淀率的影响。在硫代硫酸钠用量1.15%、140 min、70℃的最优条件下,可有效实现污酸中铼和铜的深度沉淀,其沉淀率均为99%以上。表明本工艺实现污酸中铜、铼等有价成分提取分离在技术上是可行的。

| Abstract: | Effects of dosage of sodium thiosulfate,reacting time and temperature on precipitation rate of rhenium and copper in rhenium-bearing waste acid from copper smelting were investigated applying sodium thiosulfate as precipitation reagent.The results show that deep precipitation of rhenium and copper in waste acid is realized and precipitation rate is both 99%above under the optimum conditions including dosage of sodium thiosulfate of 1.15%,reacting time of 140 min,and temperature of 70℃.It is feasible to extract and separate valuable components such as copper and rhenium from waste acid. |
