The separation effect of iron and titanium and the existence forms of iron byproducts in NH4Cl rusting solution for the reductive ilmenite which was obtained by oxidation at 1 000℃ for 1 h then reduction at 1 000℃ for 1 h with H2/CO mixed gas using Panzhihua ilmenite as raw material were studied in this paper.The results show that in an appropriate reduction-rusting system for the ilmenite with 92.40%metallization rate,the TiO2 concentration of Ti-rich material in the corrosion products can be increased to 75.12% and the addition of hydrochloric acid in the rusting solution can sequentially increase the TiO2 concentration of Ti-rich material to 81.76%.Pure Fe3O4 and γ-FeO(OH),or mixture composed of Fe2O3,γ-FeO(OH) and α-FeO(OH) in the iron byproducts for corrosion can be obtained.
