СПОСОБ ИЗВЛЕЧЕНИЯ ВАНАДИЯ ИЗ ВАНАДИЙСОДЕРЖАЩИХ МАТЕРИАЛОВ

摘要

FIELD: hydrometallurgy, namely methods for extraction of vanadium out of alkali solutions produced after leaching metallurgical slag and other vanadium-containing materials. ^ SUBSTANCE: method comprises steps of leaching vanadium-containing material for producing vanadium containing solution; extracting vanadium form prepared solution by deposition due to mixing vanadium-containing solution with ammonium persulfate in quantity multiple by 1 - 2 times relative to stoichiometric quantity necessary for generation of ammonium vanadate. Method allows produce chemically pure vanadium product containing more than 99% of V2O5. ^ EFFECT: enhanced efficiency of vanadium extraction according to simplified technological process, possibility for producing chemically pure vanadium product out of intensified alkali solutions. ^ 2 tbl
