Abstract

The extraction of molybdenum(VI) from aqueous-peroxide solutions of sodium tungstate with a trialkylamine-isooctyl alcohol mixture in kerosene was studied in relation to the ratio of the organic and aqueous phases, hydrogen peroxide and hydrogen chloride consumption, and the ratio of molybdenum(VI) and tungsten (VI) in the aqueous phase. A method for additional purification of the raffinate to remove molybdenum was developed.
