METHOD FOR PROCESSING SODIUM TUNGSTATE LIQUORS

FIELD: non-ferrous metallurgy. SUBSTANCE: proposed method resides in contacting acid sodium tungstate liquor (solution) with salt resulting from interaction of organic acid and trialkylbenzyl ammonium. Tungsten accumulated in organic phase is re-extracted with ammonia solution. EFFECT: high-efficien...

Beschreibung
Zusammenfassung:	FIELD: non-ferrous metallurgy. SUBSTANCE: proposed method resides in contacting acid sodium tungstate liquor (solution) with salt resulting from interaction of organic acid and trialkylbenzyl ammonium. Tungsten accumulated in organic phase is re-extracted with ammonia solution. EFFECT: high-efficiency commercial method for tungsten recovery from process liquors. 2 tble
