| 摘 要： | 以某多年堆积的电镀污泥为原料, 采用重选脱泥除杂、氨法浸出工艺回收其中的铜镍, 探究了碳酸铵用量、氨水浓度、液固比、浸出时间等对铜镍浸出率的影响, 确定最优工艺条件为：氨水浓度15%、浸出时间120 min、碳酸铵用量100 g/t, 液固比4〖DK〗∶1, 此时Cu平均浸出率为85.05%, Ni平均浸出率为83.45%, 实现了对该电镀污泥的回收利用。

| Abstract: | Some electroplating sludge stored in heaps for many years was taken as raw material in the test for recovering copper and nickel therein by using a process consisting of gravity desliming and ammonia leaching. The effects of ammonia concentration, liquid/solid ratio, dosage of ammonium carbonate and reaction time on the leaching rate of Ni, Cu were explored. It is found that an optimal process condition, including an ammonia concentration at 15%, 120 min leaching with the dosage of ammonium carbonate at 100 g/t, liquid/solid ratio at 4∶1, resulted in an average leaching rate of Cu and Ni reaching 85.05% and 83.45%, respectively, indicating the recycling of such electroplating sludge can be actualized. |
