摘要(Abstract)：

以镍冶炼废渣作为二次资源回收有价金属铁、镍、铜,采用球团深度还原焙烧法,通过X射线衍射(XRD)、扫描电子显微镜(SEM)和能谱(EDS)分析了不同碱度下铁、镍、铜的回收指标以及还原产物中金属相的微观形貌和存在形式。结果表明,适当提高碱度可促进金属相的还原生长,同时改善金属相在渣相中的形态结构以利于后续分离回收,而碱度过高导致金属相中夹入杂质。确定1.0为适宜碱度,该条件下得到的金属精选粉产率为40.67%,铁、镍、铜的品位分别为90.09%、0.280%、0.247%,相应的回收率分别为91.04%、56.93%、55.80%,可以实现镍渣中铁、镍和铜的富集回收。
