Extraction of molybdenum from phosphorus contained solution by ion exchange

Macropore weak base anion-exchange resin D380 is employed to extract molybdenum from raffinate phase with high concentration phosphorus of one uranium mine. The results show that when the adsorption time is 30 min, the saturation adsorption capacity of molybdenum is 248 mg/g. 80 g/L NaOH solution is used as elution reagent. When contact time of elution is 40 min, the peak concentration of molybdenum is 60 to 80 g/L and elution rate of molybdenum and phosphorus is over 99%, and elution rate of uranium is over 80%.
