铁尾矿再选技术现状及研究进展

摘要

Iron tailings are rich resources in China,which has huge potential value.It is of great significance to carry out iron tailings re-beneficiation.Iron tailings has the characteristics of low grade,fine particle size,complex iron mineral association and easy to sliming.The commonly used iron tailings re-beneficiation methods and the existing problems are reviewed,and on this basis,the development direction of tailings re-beneficiation proposed.%我国铁尾矿资源丰富,潜在价值巨大,进行铁尾矿再选具有重要的意义.铁尾矿具有品位低、粒度细、含铁矿物嵌布关系复杂、易泥化的特点.本文综述了常用的铁尾矿再选方法及存在的问题,并在此基础上提出尾矿再选的发展方向.
