Abstract The sintering experiment with low grade and high Al2O3 content of different iron ore fine proportion was done in Ansteel Bayuquan sintering production process of fine ores in Ansteel Company. The metallurgical properties of sinter were examined and analyzed; the mineralogical composition and microstructure of sinter were analyzed by the optical microscope. The results show that with the increase of the ratio of the ore, technical index of the sinter gradually reduces; the metallurgical properties of sinter were improved by adding a certain amount of low grade and high Al2O3 of ore. For overall consideration, it is feasible to adding the low grade and high Al2O3 of ore in sintering while the appropriate proportion is 5%.
