微细粒嵌布贫赤铁矿尾矿再选工艺技术研究

摘要

某处理微细粒嵌布的贫赤铁矿选矿厂,由于矿石嵌布粒度较细,生产中出现尾矿品位偏高的现象,导致金属流失比较严重.为最大限度回收尾矿中的有价成份,减少金属流失,对生产过程中产生的尾矿进行了再选工艺技术研究,为矿山实现节能减排提供技术支持.%In a certain concentration plant to deal with micro-fine particle embedded lean hematite,the tailing grade is relative high in production since the embedded particle of ore is fine,so that the metal loss is quite severe. To recover the maximum valuable components in tailings,and to reduce the metal loss,the paper carries out re-concentration process technology study for tailings generated in production.It provides technical support for energy saving and emission reduction for mine.
