| titleOfInvention | Novel method for producing vanadium pentoxide through ammonium-free vanadium precipitation |
| abstract | The invention relates to a novel method for producing vanadium pentoxide through ammonium-free vanadium precipitation, specifically to an ammonium-free vanadium precipitation method for producing vanadium pentoxide from high-concentration vanadium-containing liquid obtained in a process for extraction of vanadium from bone coal and a process for extraction of vanadium from vanadium slag. According to the invention, tetravalent vanadium in back extraction liquid obtained by subjecting raw ore of a vanadium extraction process to acid leaching, extraction and back extraction is oxidized into pentavalent vanadium at first so as to form a supersaturated system of pentavalent vanadium, and crystallization is carried out to obtain a polyvanadic acid precipitate; or a high-concentration vanadium-containing solution obtained by subjecting ore or vanadium slag to roasting, acid leaching, ion exchange or extraction-back extraction is maintained at a certain temperature and uniformly stirred and then a novel vanadium precipitating agent is added to allow precipitation of polyvanadic acid to continue; a more insoluble vanadium pentoxide hydrate is produced due to reduction in acid concentration; then solid-liquid separation is carried out to separate mother liquor with high impurity content, and powdery vanadium pentoxide hydrate is obtained; and the powdery vanadium pentoxide hydrate is sintered so as to obtain vanadium pentoxide. |
