This paper studies the effect of mixed blowing CO2–O2 gas on the extraction of vanadium and adopts blowing flow and stage blowing, two types of variables, to study the effect of both on the extraction of vanadium from hot iron. The initial blowing temperature of the experiment was set to 1300 °C. The experimental results showed that the whole process is sprayed with 15% CO2, and the optimum blowing flow rate is 1.714 L/(min kg). The stage blowing has better vanadium extraction with carbon retention effect, compared with the whole blowing of 10% CO2, and the end point temperature of the molten pool is decreased by 17 °C. The stage blowing is injecting 10% CO2 in the initial and injecting 15% CO2 in the middle and late period. And it has a higher vanadium oxidation rate than the whole blowing 10% CO2, which can reach 95.14%.
