Abstract
FIELD: chemical industry. SUBSTANCE: recovery of molybdenum from sodium tungstate solutions is done by extraction or sorption using anion exchanger in the presence of sulfide containing reagent and by addition of phosphorus as phosphoric acid salts. Phosphorus is added in amount of 0.025 to 6 g/l. EFFECT: more efficient recovery method. 2 cl, 7 tbl
