Abstract AITranslate

Study is made of the possibility and technical requirements of separating tungsten from high W- containing Na2MO4 solution by Fe （OH）3 adsorption. The results showed that each absorption resulted in 70 % ～80 % tungsten separation from molybdenum at pH = 7.0 and with consumption 2～4 times more than that of WO4^2- . When WO3/Mo = 0. 445, WO3/Mo is reduced down to 0.17～ 0.18 through the first absorption. A new method is developed to neutralize sodium molybdate solution with HCl and NH4Cl as neutralizer, which can notably improve recovery and separating effect.
