高纯铁制备技术综述 张力1,徐志高1,罗远辉1,孙辉1,王力军1 (1.北京有色金属研究总院,北京,100088) 摘要:本文介绍了溶剂萃取,离子交换,电解精炼和区域熔炼等冶金提纯方法在高纯铁制备过程中的应用.采用溶剂萃取法和离子交换法,可以除去溶液中的大多数金属杂质,得到纯度为4N的高纯铁溶液.通过氢还原或电解精炼,可进一步去除杂质元素并获得纯度为6N的金属铁材料.区域熔炼法可对铁进行进一步精炼,使纯度达到极限.对不同的原料纯度以及不同的产品纯度要求,采用的工艺方法也有相应的变化,但一般采用几种方法相结合的工艺路线制备品质优良的高纯铁. 关键词:高纯铁; 溶剂萃取; 离子交换; 电解精炼; 区域熔炼; high purity iron; solvent extraction; ion exchange; electrolysis refining,zone melting......
