铜炉渣的资源化利用现状及展望
Current status and prospect of copper furnace slag re-utilization
分析了不同冶炼工艺所产生铜炉渣的特性及主要成分,归纳总结了铜炉渣在有价组分回收领域的资源化利用现状。铜炉渣中铜、铁的回收主要采用浮选和磁选工艺,分别阐述了浮选铜组分、磁选铁组分的研究现状和工艺方法的优缺点;概述了铜炉渣在建筑、催化、微电解和微晶玻璃材料中的应用现状和存在的问题。未来,进一步加强和优化铜炉渣中铜铁等组分的选矿工艺,研发高效选矿药剂,进一步提高有价金属的回收率;研发铜炉渣固废处理新技术、探索新的利用途径是促进铜炉渣的高值化利用的重要方向。
The characteristics and main components of copper furnace slag produced by different smelting processes are analyzed,and the current re-utilization situation of copper furnace slag in the valuable components recovery field is summarized.The recovery of copper and iron in copper furnace slag mainly adopts flotation and magnetic separation processes,respectively.Research status of copper components flotation process and iron components magnetic separation process is expounded,and the advantages and disadvantages of these processes are described.In addition,the current application status and existing problems of copper furnace slag in the construction,catalysis,microelectrolysis and microcrystalline glass materials are outlined.In the future,it is suggested to further strengthen and optimize the beneficiation processes for copper and iron components in copper furnace slag,develop efficient beneficiation chemicals,and further improve the recovery rate of valuable metals.It is also proposed that research and development of novel technologies for the treatment of copper furnace slag and exploring new re-utilization ways are important directions to promote the high-value utilization of copper furnace slag.
