摘要
线路板是绝大多数电子产品达到电路互连的不可缺少的主要组成部件,其中蕴含许多有价金属,如铜、铁、铝、锡、铅、金、银等,其回收方法以物理法为主。介绍了目前占主导地位的几种物理法回收技术及工艺流程,并且提出自己的湿法处理工艺。
The circuit boards are the chief and indispensability constitutes of most electronic products to reach electro-circuit interlinkage. In these boards, there are a great deal of valuable metals such as copper,iron,aluminum, sternum,lead,gold,silver and so on. Usually one of the important recovery methods is the physical recovery. Some techniques and fiowsheets of the metal recovery from discarded PCBs by several physical methods are introduced, on the other hand, a novel wet flowsheet is put forward.
