| 摘 要： | 针对传统氨浸工艺浸出率较低现状，采用氧化氨浸工艺浸出回收铜镉渣中的镉、锌和铜.为了确定氧化氨浸工艺的最佳浸出条件,采用正交实验的方法研究了铜镉渣氧化氨浸的影响因素.结果表明:在氨水浓度3.7 mol/L，铵离子浓度5.0 mol/L和(NH4)2S2O8浓度30 g/L、液固比6∶1的条件下，镉、铜的浸出率达到99%,同时锌的浸出率达到96%，浸出率明显高于传统氨浸方法.

| Abstract: | Aimig at the low leaching rate of the traditional ammonium leaching process,the oxidizing ammonium leaching process of extracting cadmium,zinc,and copper from copper-cadmium slag is adopted.The effect of copper-cadmium slag was studied by orthogonal tests in laboratory in order to find out the optimum ammonia leaching conditions with oxidants.The optimum conditions obtained are as follows:ammonia concentration 3.7 mol/L,ammonium ion concentration 5.0 mol/L,(NH4)2S2O8 concentration 30 g/L,and liquid to solid... |
