摘　　要：中和渣通常含有锌、铜、镍、钴、锗等有价元素,是综合回收重要的二次资源。目前国内中和渣处理方法大致有三类:1) 通过火法处理回收有价元素;2) 通过湿法处理回收有价元素;3) 替代水泥在建筑领域或作为辅剂进行直接利用。本文总结归纳了以中和渣为研究对象,针对不同有价金属综合回收的工艺流程及过程参数等,为冶金企业的工艺选择提供参考依据。Neutralization slag usually contains some valuable elements, such as zinc, copper, nickel, cobalt and germanium, and it is an important secondary resource for comprehensive recovery. At present, there are three kinds of methods for treating neutralization slag: 1) to recover valuable elements by fire treatment;2) recovery of valuable elements through wet treatment;3) in the field of con-struction instead of cement or as an auxiliary agent for direct use. This paper summarizes the process flow and process parameters of the comprehensive recovery of different valuable metals by taking neutralization slag as the research object, and provides reference for the process selection of metallurgical enterprises.
