| description | In this study, a clean pellet production method of calcium roasting and sulfuric acid leaching of vanadium from vanadium and titanium magnetite concentrates is proposed, which can effectively separate vanadium and iron, and the pellets after acid leaching and vanadium extraction can be used as raw material for iron making after secondary roasting. During the experiment, only 2% Ca(OH)<sub>2</sub> was added as the calcifier to make pellets, and vanadium was extracted by acid leaching after calcination. Under the optimum conditions, the vanadium leaching rate was 74.51%, and the iron leaching rate was only 1.05%. After secondary roasting, the compressive strength of the pellets was 2358 N, and the qualification rate was 97%. Additionally, after acid leaching and vanadium extraction, the impurities in the pellet were partially removed, and the iron content of the pellet increased by 6.6%, which is more conducive to subsequent ironmaking. The roasting and acid leaching experiments show that based on the production of iron smelting pellets, the use of pellets can better extract vanadium from the titanium magnetite concentrate, while avoiding the problems of excessive additives to reduce the iron grade of pellets. Or the pursuit of high vanadium extraction rate pellets, which can be seriously damaged and difficult to use later. This process can perform a comprehensive utilization of vanadium titanium magnetite, and has certain guiding significance for industrial production. |
