| 摘 要： | 印刷电路板废粉末料的资源化和无害化问题日益得到重视。以报废印刷电路板经机械粉碎和分选后的非金属粉(铜含量1%～5%)为原料,采用"氨浸—脱氨—干燥"的工艺制备碱式碳酸铜,设计了实验装置,考察了氨浸分离工艺条件,通过实验验证了其可靠性:铜的回收率达到98.8%以上,获得了纯度不小于98.0%的碱式碳酸铜,采用X射线粉末衍射(XRD)﹑扫描电镜(SEM)和能谱(EDS)方法对产品进行了分析和表征。

| Abstract: | The recycling of copper from waste PCB and deep processed into basic copper carbonate has attracted more and more attentions.A new method of manufacturing basic copper carbonate using "ammonia leaching-deamination-drying " technique from copper content range from 1% to 5% of waste PCB powders has been presented.The production devices were designed perfected,the ammonia leaching separation and roasting process conditions have been investigated,and the reliability of this manufacturing process has been tested and verified practically.The recovery ratio of copper is more than 98.8% and the purity of basic copper carbonate is no less than 98.0%.It was characterized by XRD,SEM and EDS. |
