Industrial application of the technique of removing Mo by a combination of moving packed bed and fluidized bed ion exchange

摘要

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 in APT (Ammonium Paratungstate) is controlled steadily below 18 x 10~(-6), in the case of treating the feed liquor containing Mo 1.4 g/L. The technique is simple and convenient in operation, good reusability of resin, loss consumption of desorption reagent and little pollution on environment. The loss of tungsten is less than 0.5%. The technique has been proved to be an economical and efficient process for Mo removal.
