Abstract: An iron ore in Yili area of Xinjiang contains 32.16% iron and 26.72% magnetic iron. In order to rationally develop and utilize the iron ore resources，based on the research and analysis of the properties of the raw ore，the beneficiation process tests such as magnetic separation preconcentration and discard tail，stage grinding，stage low-intensity magnetic separation and magnetic column separation were carried out. The results show that the tailings with a yield of 34.70% can be discarded by wet pre-concen‐ tration and tailings discarding under the condition of magnetic induction intensity of 350 mT when the raw ore is crushed to -12 mm，and the TFe grade of the pre-concentrate is enriched from 32.63% to 45.81%， and the mFe recovery rate can reach 99.42%. The pre-concentrate was subjected to three-stage grinding， two-stage low-intensity magnetic separation，and three-stage magnetic separation column separation. When the final grinding fineness of - 0.074 mm accounted for 95%，an iron concentrate with a yield of 39.40%，Fe grade of 65.11%，and Fe recovery of 78.74% was obtained. The test results provide a techni‐ cal reference for the iron separation process of this ore and similar refractory iron ore.
