| titleOfInvention | Method of producing vanadium pentoxide from vanadium-containing slag |
| abstract | FIELD: chemistry. n SUBSTANCE: invention relates to extraction of pure vanadium pentoxide from slag obtained during production thereof. The method involves taking ground vanadium-containing slag, fusion thereof with sodium hydroxide to obtain sodium metavanadate. The sodium metavanadate is then leached with water and the solution is separated from the solid phase. The obtained solution is then mixed with an inorganic acid to achieve pH≤4 and a sorbent is added, the sorbent used being powdered coal which is modified with cation-active nitrogen-containing surfactants. After the sorption process, the spent sorbet is separated from the liquid phase, dried and calcined at temperature of 600-640°C to obtain pure vanadium pentoxide. The cation-active nitrogen-containing surfactants used are, for example, lauryl dimethylbenzyl ammonium chloride, cetylpyridinium chloride and polyhexamethylene guanidine hydrochloride. n EFFECT: wider raw material base for producing vanadium pentoxide, providing high output and high degree of purity of vanadium pentoxide. n 4 cl, 1 tbl, 3 ex |
