铜精炼过程中砷、锑的脱除研究现状

由冰铜吹炼而成的粗铜中含有一定的杂质, 这些杂质会对铜的工业性能产生不同程度的影响, 因此需要对粗铜进行精炼处理。为了进一步提高阴极铜质量, 生产满足市场需求的铜产品, 在火法、电解精炼等方面对有害杂质进行有效处理成为了国内外专家学者研究的热点。其中火法精炼处理砷、锑的方法有: 氧化挥发法、碱性造渣法、真空精炼法、FRHC技术等; 电解精炼处理砷、锑的方法有: 电积法、溶剂萃取法、吸附法、离子交换法、电解液的自净化等。笔者对火法、电解精炼中砷、锑的处理方法进行综述和展望, 以期对今后研究火法铜中杂质的处理提供帮助。 

Research status of arsenic and antimony removal in copper refining process

The crude copper from matte smelting contains certain impurities that have different influence on the industrial properties of copper.Hence the crude copper needs to be refined.In order to further improve the quality of cathode copper and produce copper products that meet the market demands,effective treatment of harmful impurities in the aspects of fire process and electrolysis refining has become a research focus of domestic and foreign experts and scholars.The methods of treating arsenic and antimony by fire refining include:oxidative volatilization,basic slag making,vacuum refining,FRHC technology,etc.Electrolytic refining processes of arsenic and antimony include:electrodeposition,solvent extraction,adsorption,ion exchange and self-purification of electrolyte.The paper reviewed the treatment methods of arsenic and antimony in fire and electrolysis refining and looked ahead in order to provide help for the future research on treating impurities in copper by fire.
