Abstract: In order to recover 0～5 mm iron ore with industrial value from iron tailings in Anhui and improve the utilization rate of iron resources，a series of magnetic separation dry separation tests are carried out，and a suitable magnetic separator is determined and successfully applies in the industrial field.The re⁃ sults of industrial production show that the average grade of magnetic iron in 0～5 mm fine-grained stone powder ore feeding is 8.14%. After industrial magnetic separation，the average grade of magnetic iron in stone powder concentrate is 17.45%，the average grade of magnetic iron in stone powder tailings is 1.27%， and the recovery rate of magnetic iron in 0～5 mm fine-grained stone powder is 90.62%. The recovery and utilization of iron resources are realized，the economic benefits are remarkable，the pollution of tailings to the mining area is reduced，and the construction of waste-free green mines and the sustainable development of mines are promoted.
