There are almost ten billion tons of vanadium-bearing titanomagnetite in Panzhihua-Xichang area. However, iron ores in Hongge, which has the most abundant reserves in the four mine areas in Panzhihua, was not utilized sufficiently so far. The reason was that Hongge mining containd 0.95%~1.15% Cr2O3 besides iron, Cr2O3 has a high melting temperature which influences the blast furnace reduction and slagging process. Therefore, in the blast furnace process, Cr is hope to reduced into molten iron, which can reduce slag viscosity problems. Slag iron reduction reaction was conducted by a high temperature Si-Mo furance. Analysised by XRD and XRF, we can see that with the increase of TiO2, the content of Cr in the hot metal is decreased when balanced. And during the initial stage of the reduction reaction, the reaction kinetic model is a first-order.
