摘要
铼是一种极其稀缺而且分散的贵金属，我国铼资源十分有限。本文详述采用大孔型阴离子交换树脂Ｄ２９６从冶铜废液中直接提取铼酸铵的新工艺方法。新工艺先进实用，铼提取率可达９９％，具有十分显著的经济效益、社会效益和环保效益。
The new technology for extracted NH 4ReO 4 from the waste liquid of copper smelting by anion exchanger D296 were detailed described in this thesis.It is not necessary to remove other ions from the complex solution.The process is advanced and practical,the result is very effective and the rate of Re recovery is as high as 99%.
