Uranium and molybdenum recovery from copper

01-03-2019  Uranium recovery: (2) 2 RCl + UO 2 SO 4 2 2 − → R 2 UO 2 SO 4 2 + 2 Cl −. Molybdenum recovery: (3) RCl + HMoO 4 − → R HMoO 4 + Cl −. According to Table 4, because of the higher selectivity for sulfate than chloride ions, it is possible to recover uranium and molybdenum and exchange them during the elution stage.
