Abstract: In this paper,the recovering experiments were studied for an iron tailing.This research was aimed at recycling of waste iron ore resources by the technology of upgrading iron and degrading silicon.Due to the characteristics of tailing with fine embedded size,high content of interlocked mineral,and the iron was mainly existed for hematite-limonite ore and few magnetites,the fine grinding-magnetic separation-counter floatation process was chosen for the recycling experiments.Gringding the iron tailing to the content of-0.038 mm 90%,the low intensity magnetic separation was used to enrich magnetite,and the strong magnetic separation was used to enrich hematite-limonte.Then the rough concentrate of low intensity magnetic separation and strong magnetic separation was treated by counter floatation.By one roughing,one cleaning,the iron concentrate was obtained with the TFe grade 58.03%,TFe recovery rate 53.27% and SiO₂ grade 4.82%,which reached the test targets.
