摘　　要：阐述了提高铁精矿质量的重要性和高效分选新工艺及新设备。国内众多选矿厂进行铁矿石提铁降硅（杂）生产系统的改造与扩建，生产出含铁66％-69％、含SiO2 4％左右的高质量铁精矿，有效地提高了炼铁高炉入炉铁品位，减少了高炉炼铁废气、废渣的排放量，实现了高炉炼铁节能减排及集团经济效益高效化。In this article, the importance of improving quality of iron concentration and new high - efficient technologies and equipments for it are discussed. The high - quality iron concentration of 66% - 69%TFe and about 4% SiO2 was produced by production system improved and expanded for increasing iron grade and reducing SiO2 content in many domestic concentrators. Thus, the iron gradc of blast furnace charge was increased, and emission of waste gas and slag of blast furnace was reduced effectively. By these, energy saving, emission reduction, efficiency increasing and economic benefits maximization were realized.
