综述了几种铜渣贫化技术.基于铜渣的物相结构,分析了铜渣火法贫化、湿法提取及缓冷选矿3种方法的贫化机理,并讨论了各方法的贫化效果.结合氯化法在处理复杂物料中的优势,为实现渣中铜的高效提取,提出了一种铜渣氯化焙烧-烟气捕集回收铜的研究思路.
The representative copper recovery technologies are reviewed. Based on the phase composition of copper slags, the dilution mechanism of copper slags pyrometallurgical dilution, hydrometallurgical extraction and mineral separating method is analyzed, and the dilution effect of these methods is discussed. According to the advantage of the chlorination process treatment with complex material, the research idea of copper slags chlorination-flue gas collection for realizing the high effective extraction of copper from copper slags is put forward
