Method for implementing vanadium extraction through carrying out sodiumtranslated pellet roasting on vanadium slags

The invention belongs to the field of vanadium extraction chemical technologies, and discloses a method for implementing vanadium extraction through carrying out Na-modification pellet roasting on vanadium slags. The method comprises the following steps: (1) mixing vanadium slags with a Na-modification additive; (2) spraying an aqueous solution of a binder to the surface of a mixture obtained in the step (1), and preparing the obtained object into a pellet; and (3) roasting the pellet, crushing the pellet, dissolving the crushed pellet in water, and leaching the obtained product. According to the method for implementing vanadium extraction through carrying out Na-modification pellet roasting on vanadium slags disclosed by the invention, the leaching rate of vanadium is greatly improved, and a phenomenon that vanadium slags are bonded in the process of high-temperature roasting is also avoided; and in a Na-modification pellet roasting method in the invention, residues produced after vanadium is extracted are not required to be added, therefore, the Na-modification pellet roasting method is simple in process and easy to use, wide in application range and low in cost, and has extremely high social and economic benefits.
