The principle of vanadium extraction with traditional sodium roasting technologies and general situation of flue gas pollutants were introduced in this article. A new roasting process and flue gas treatment technology were proposed, whose principle was expounded, which was compared with traditional techniques and methods. Based on the pilot test report and monitoring data, the technological feasibility of flue gas pollution prevention and control measures were analyzed. The problems and reasons in the process of flue gas emission were explored, and the improvement measures were proposed, which provided helpful information on flue gas pollutants control for enterprises.
