还原熔炼法从谦比希铜冶炼厂转炉渣中回收钴

摘要:研究从赞比亚谦比希铜冶炼厂转炉渣中回收钴的还原熔炼过程.实验考察还原剂用量、熔炼温度、保温时间及渣型改善剂CaO和TiO2的添加对还原熔炼金属回收率的影响.采用X射线衍射、扫描电子显微镜及能谱分析对所得贫化渣和含钴合金进行表征.结果表明,在优化条件下,转炉渣中钴、铜、铁的回收率分别为94.02%,95.76%和小于18%;贫化渣的主要物相组成为铁橄榄石和铁尖晶石,含钴合金中主要含有金属铜、含钴铜的铁合金和少量的硫化物.Abstract:The reduction smelting process for cobalt recovery from converter slag of the Chambishi Copper Smelter in Zambia was studied.The effects of reducing agent dosage,smelting temperature and time and the addition of slag modifiers(CaO and TiO2)were investigated.In addition,the depleted slag and cobalt-beating alloy were characterized by X-ray diffraction,scanning electron microscopy and energy dispersive spectroscopy.Under the determined conditions,94.02% Co,95.76% Cu and less than 18% Fe in the converter slag were recovered.It was found that the main phases of depleted slag were fayalite and hercynite; and the cobalt-bearing alloy mainly contained metallic copper,Fe-Co-Cu alloys and a small amount of sulfide. 作者: 翟秀静[1]  李乃军[2]  张旭[1]  符岩[1]  姜澜[1] Author: ZHAI Xiu-jing[1]  LI Nai-jun[2]  ZHANG Xu[1]  FU Yan[1]  JIANG Lan[1] 作者单位: 东北大学材料与冶金学院,沈阳,110819沈阳大学理学院,沈阳,110044 期 刊: 中国有色金属学报(英文版)   ISTICEISCI Journal: Transactions of Nonferrous Metals Society of China 年,卷(期): 2011, 21(9) 分类号: X756 TF816 关键词: 转炉渣    回收钴    还原熔炼    渣型改善剂    含钴合金    Keywords: converter slag    cobalt recovery    reduction smelting    slag modifier    cobalt-bearing alloy    机标分类号: TF8 X75 机标关键词: 还原熔炼    熔炼法    铜冶炼厂    转炉渣    回收钴    converter slag    electron microscopy    energy dispersive    含钴合金    addition    扫描电子显微镜    reducing agent    金属回收率    phases of    优化条件    物相组成    铁尖晶石    铁橄榄石    射线衍射    熔炼温度 基金项目: the National Key Technology R&D Program of China 还原熔炼法从谦比希铜冶炼厂转炉渣中回收钴[期刊论文]  中国有色金属学报(英文版) --2011, 21(9)翟秀静  李乃军  张旭  符岩  姜澜研究从赞比亚谦比希铜冶炼厂转炉渣中回收钴的还原熔炼过程.实验考察还原剂用量、熔炼温度、保温时间及渣型改善剂CaO和TiO2的添加对还原熔炼金属回收率的影响.采用X射线衍射、扫描电子显微镜及能谱分析对所得贫化渣和含钴...
