FIELD: metallurgy; methods of extraction of vanadium from production solutions; vanadium production technology and analytical chemistry.
SUBSTANCE: proposed method consists in extraction of vanadium from production solution by di-2-ethyl hexyl phosphoric acid in organic diluent. Extraction is performed in presence of sodium sulfate in the amount of 0.5-0.8 mole/l at pH= 2.0-2.6.
EFFECT: facilitated procedure; complete separation of vanadium at simultaneous reduction of extracting agent consumption.
