The application of the technique of removing molybdenum by moving packed bed and fluidized bed ion-exchange in a factory was described. The data showed that the Mo removal efficiency is above 99%, and the Mo content inAFT (Ammonium Paratungstate) is controlled steadily below 18 × 10-6, in the case of treating the feed liquor containing Mo1.4 g/L. The technique is simple and convenient in operation, good reusability of resin, loss consumption of desorption rea-gent and little pollution on environment. The loss of tungsten is less than 0.5%. The technique has been proved to be aneconomical and efficient process for Mo removal.
