用氨浸从电镀污泥中回收镍的工艺研究

Nickel Recovering Technology from Electroplating Sludge in the Way of Ammonia-leaching

镍是十分重要的战略原料 ,但资源匮乏。金属镍性能稳定 ,是常用的镀层材料。电镀厂的污泥不仅污染环境 ,而且浪费资源。简述了氨浸法提取镍的基本原理 ,总结了氨浸法从电镀污泥中回收镍的基本工艺和规律。

Nickel was a very important raw material, yet the resources are deficient. The performance of metal nickel was stable, so often used as electroplating material. The electroplating sludge without treatment not only do harm to the environment, but also waste valuable resources. The principle of nikel recovering from the electroplating sludge were described, and the technology and the regular pattern were summed up .
