Molybdenum (Mo) is a strategic metal element, and recovery of Mo from low concentration Mo-containing solution is significative to alleviate the Mo resources shortage. In this study, the treatment of low-concentration Mo-containing solution by Fe3+ addition was investigated by batch experiment, and the effects of main parameters including molar ratio of Fe:Mo, pH value, initial concentrations and reaction time on the recovery of Mo were studied. The results showed that the Mo is transformed into precipitation rapidly with a Mo recovery of 100% in 5 min when the pH range is 4~6 and molar ratio of Fe:Mo is greater than 1:4, indicating the reaction between Mo and Fe readily approaches chemical equilibrium. Moreover, the initial concentration of Mo in the solution has little influence on the recovery of molybdenum. This technology can realize the enrichment and recycling of molybdenum and the purified solution can meet the industrial discharge standard.
