STUDY ON TECHNOLOGY OF REDUCING FE IN VANADIUM PENTOXIDE
Using ammonium metavanadate as raw material,Fe(OH)3 precipitation method is used to remove iron from the leach solution.By utilizing the difference in solubility product and controlling the pH value of the solution,metal i-ons can react to form precipitates of iron hydroxide,thereby removing impurity iron.And the optimal process parame-ters for iron removal are verified by experiments at different temperatures,pH values and reaction times,to reduce di-vanadium pentaoxide Fe,so as to achieve the most favorable conditions for reducing Fe in vanadium pentoxide.
