结晶法回收电镀污泥中有价金属的工艺研究

Crystallization Process Study on Recycling Valuable Metals from Electroplating Sludge

着重介绍综合利用海滨的巨大风能和地场对电镀污泥酸解液进行自然浓缩、结晶提取浸出液中的铜、镍、铬、锌等金属及其化合物的工艺方法,进而阐述利用天然海边晒场资源浓缩结晶回收电镀污泥中的有价金属,既节能,又环保,可实现循环生产。

Great wind and threshing ground focuses on comprehensive utilization of the beach,on electroplating sludge acid leaching solution of natural enrichment,Crystal extraction from liquid metal such as copper,zinc,nickel,chromium and its compounds method.Thus explained by natural seaside drying yard resources concentration crystallization recycling of valuable metals from electroplating sludge,energy-saving and environmental protection,cycle production can be realized.
