Abstract: Magnetite samples were magnetically separated with a magnetic tube and artificial magnetic separation. The contents of TFe, P, S, V₂O₅, TiO₂, SiO₂, Al₂O₃, CaO, MgO, Sn, Cu, Pb and Zn in the magnetite samples were determined. The results of the two separation methods were consistent. Consequently, artificial magnetic separation in subsequent experiments was chosen in order to simplify the process. The average content of mFe in mining area A (22.42%) was lower than that in mining area B (22.59%), but the content of TFe in the magnetic material of mining area A magnetite samples (>66%) was higher than that in mining area B ( < 57%). The results indicate that the effect of mineral processing of mining area A is much better than that of mining area B since the content of TFe in magnetic material can better reflect processability. The contents of P and S were 0.328% and 0.271% in the magnetite ore samples, 0.021% and < 0.005% in the magnetic material, which met the requirements of the iron ore smelting standards as P<0.15% and S<0.15% in the magnetite. The contents of V₂O₅ and TiO₂ were 0.156% and 1.37% in the magnetite ore samples, 0.823% and 13.62% in the magnetic material, which meet the requirements of the iron ore smelting standards as V₂O₅>0.15% and TiO₂>3% in the magnetite. The magnetite with a(CaO+MgO)/(SiO₂+Al₂O₃) ratio of 0.876 is the self-fluxing ore, but the magnetic material of this magnetite with a (CaO+MgO)/(SiO₂+Al₂O₃) ratio of 0.453 is acid ore. This indicates that the evaluation of the magnetite does not depend on the contents of each component in the ore sample, but rather depends on the contents of each component in the magnetic material of the magnetite. Through the determination of magnetic materials in magnetite ore, a new evaluation method for magnetic separation and smelting has been determined.
