Study on Tungsten and Molybdenum Separation in the Ammonium Molybdate Crystallization Process AITranslate
Abstract AITranslate
Based on the difference in property of isopolyacid or heteropolyacid between tungsten and molybdenum,the crystallization process of ammonium molybdate feed solution was operated by acid precipitation or evaporation under various experimental conditions.And the separation effect between tungsten and molybdenum in that process was investigated.The results show that the separation degree of tungsten from molybdenum is low in the acid-precipitation process,but obviously improved in the case of ammonium phosphate addition.The evaporation process is influenced by final pH value and ratio of tungsten to molybdenum in feed solution.Especially when the ratio is large,the difference in crystallization rate between tungsten and molybdenum is obvious,resulting in good separation effect.
