Abstract: In view of the problem that the massive accumulation of iron tailings not only occupies land,but also causes harm to ecological environment,the general idea to realize the utilization of iron tail⁃ ings is to take iron tailings as secondary resources,use iron tailings to prepare high value-added materi⁃ als,so as to give products with larger market radius and utilization value. Based on the description of iron tailings components,the main methods of high-value utilization of iron tailings are reviewed,and the re⁃ search progress of high-value ultilization of iron tailings in valuable components recovery,ceramics prepa⁃ ration,porous materials preparation,insulation wall materials preparation and other functional materials are summarized,as well as the problems existing in the process of high-value utilization. Finally,the chal⁃ lenges of high-value utilization of iron tailings are put forward,and the direction of high value utilization of iron tailings in the future is prospected.

Key words: iron tailings, recycling, high-value ultilization
