摘　　要：高品位铁精矿是选矿的深加工产品，又是一种很有发展潜力的新型功能材料。目前高品位铁精矿主要分为两类：其一是指铁品位高于69．00％、二氧化硅及其它杂质含量小于3．00％的磁铁矿精矿，主要用于生产海绵铁；其二是指铁品位高于71．50％、二氧化硅及其它杂质（酸不溶物）含量小于0．2％～0.3％的磁铁矿精矿，主要用于粉末冶金、磁性材料等领域。介绍了高品位铁精矿用于生产海绵铁和粉末冶金的现状及前景展望。High grade iron concentrate is a deep-processed product which is also a novel functional material that has great development potential. It is now mainly classified into two types： one is magnetite concentrate with an iron grade higher than 69.00% and a content of silica and other impurities of less than 3%, which is mainly used to produce sponge iron; the other is also magnetite concentrate with an iron grade higher than 71.5% and a content of silica and other impurities （ substances insoluble in acid ） of less than 0.2% ~ 0.3% , which is mainly used in the fields of powder metallurgy and magnetic materials. The prospect and the application state of high grade iron concentrate are described.
