In order to utilize the chromium resource in chromium containing vanadium extraction residue, it is a promising method to prepare chromium iron with the residue. The composition of residue refer to the vanadium-chromium slag which experienced vanadium extraction. Then it has been reduced under 1300oC, 1350oC and 1400oC at the reduction time of 1h, 2h and 3h respectively. The reduced sample have been smelting separated by induction furnace. Then the content of chromium and iron in metallic phase have been investigated by inductively-coupled plasma spectrometer. The results indicate that chromium iron carbide (Cr, Fe)3C7 is intermediate phase and titanium has been reduced during reduction process. When the sample has been reduced under 1400oC at the reduction time of 3h, metallic phase become the dominate phase, and reduction reaction has been almost completed. Moreover, the content of the metal phase reaches 10.19%.
