Abstract: The industrial vanadium trioxide is powdery with bulk density of 0.6~1.2 g/cm³,which is not good for recovering vanadium in the following vanadium alloy smelting process.Due to the high melting point of V₂O₃,only the physical method could be employed to increase the V₂O₃ density.In this paper,the nonslurry pelletizing process is introduced.Granular V₂O₃ with high relative bulk density can be acquired by reducing the roller's rotation speed and increasing the roller's pressure,etc.The bulk density of the granular V₂O₃ increases to 1.7~2.1 g/cm³ through employing 5 exhaust processes and exerting 120 N/cm² of mechanical molding pressure during pelletizing.V yield increases from 89%~92% to 93%~96% or even higher by using high-density V₂O₃ in the FeV metallurgy process.The V content in FeV alloy also slightly increases.
