FIELD: metallurgy.
SUBSTANCE: procedure for extraction of tungsten (VI) from solutions of cations of heavy metals consists in sorption of tungsten (VI) at value of pH of solution less, than value of pH of hydrolytic sedimentation of cations of heavy metals. As sorbent at sorption there is used activated bone coal.
EFFECT: efficient procedure for selective extraction of ions of tungsten from water solution of cations of heavy metals.
