FIELD: metallurgy.
SUBSTANCE: invention can be implemented for extraction, purification and concentration of vanadium, for example at processing re-circulated mother solutions of production V2O5 and acid solutions of leaching ashes after black oil burning. The method of extracting vanadium from weak-acid mediums consists in extracting with nitrogen containing extracting agent, in the capacity of which N-(2-hydroxy-5-nonylbenzyl)-ββ-dihydroxyethylamine (NBEA) is used in organic diluter. After extraction re-extraction of vanadium is performed with ammonia solution.
EFFECT: upgraded degree of vanadium extracting from weak-acid solutions.
