FIELD: metallurgy.
SUBSTANCE: procedure for extraction of niobium from water solution containing fluorine consists in sorption by contacting solution and anionite. Anionite is subjected to acidic or water treatment before sorption. Sorption is carried out with anionite of grade ANP containing exchange groups 
at pH=2-4.
EFFECT: optimal conditions for fast and efficient procedure for niobium extraction out of water solution containing fluorine.
