Method of vanadium extraction |
| abstract |
FIELD: metallurgy. n SUBSTANCE: invention concerns hydrometallurgy. Particularly it concerns method of vanadium extraction. Method includes leaching of vanadium-bearing material by water solution of soda with receiving of alkaline vanadium solution. Received solution is mixed with monohydric alcohol and implemented aliquation of formed mixture for two phases: upper - soda-alcohol, which is subject to regeneration, and bottom - in the form of sodium vanadate solution, where it is concentrated vanadium. Then phase separation is implemented. From bottom phase it is precipitaled vanadium by means of addition to it and mixing with ammonium salt of ammonium carbonate, taken in 1-3-fold amount with respect to stoichiometric quantity, necessary for formation of ammonium vanadate. Ammonium vanadate is dried and burnt for receiving of vanadium pentoxide. n EFFECT: simplification of process and receiving from lye vanadium pentoxide of higher-purity. n 3 tbl, 1 ex |
