摘要

摘要:
铜渣属于重要的二次资源，产量大，富含有价金属组分，在工业中有其重要的利用价值。目前铜渣的主要利用方向为提取有价金属元素和减量化应用。通过对铜渣的特性、来源以及综合利用现状评述可知，采用浮选法、火法、湿法、联合法或生物浸出法处理铜渣都存在一定的不足，减量化应用也存在相应的问题。最后指出未来铜渣利用的研究方向。

Abstract:
Copper slag is a vitally secondary resource, more quantities, richen in valuable metal elements, which has an important utility in industries. Recently, the main utilization direction of copper slag is to extract valuable metal elements and reduce the application. It can be seen that through the review of the characteristics, sources and previous studies of copper slag, there are some deficiencies in the treatment of copper slag via flotation method, fire method, wet method, combined method or bioleaching method, and the same as in the application of reduction. Ultimately, the research and application direction of copper slag in the future are pointed out, so that the copper slag can be applied reasonably and comprehensively.
