Research on Uranium and Molybdenum Recovery Technology in Molybdenum Back Extraction Three-Phase Compound
A uranium molybdenum mine extracts molybdenum from the acid leaching solution containing molybdenum,and a large number of extracted three-phase substances are produced in the process of ammonia reverse extraction of molybdenum.According to the material composition of the filter residue and the existing form of uranium and molybdenum,the experimental study on the recovery and extraction of uranium and molybdenum is carried out.The experimental results show that it is difficult to extract uranium and molybdenum in one step under the same system.The step-by-step treatment process of"first water leaching molybdenum and then acid leaching uranium"can achieve the efficient extraction of uranium and molybdenum.The feasibility of the step-by-step treatment process is verified by the expanded test,and it is investigated that the plate and frame pressure filtration can achieve good results.The uranium leaching rate can reach 98.93％and the molybdenum leaching rate can reach 96.08％.The obtained molybdenum containing solution is combined with the acid precipitation mother liquor and then molybdenum is extracted,and the uranium containing solution is combined with the uranium extraction mother liquor and then uranium is extracted,so as to realize the organic combination with industrial production,The influence of organic phase and ammonium ion in solution on oxygen pressure leaching production system is avoided.
