Abstract This study focuses on the East Qinling molybdenum mine area, where the pollution of heavy metals in the surrounding aquatic environment and the mineralogical characteristics of the associated sediment were analyzed. Furthermore, the study examined the migration behavior of molybdenum (Mo) during the leaching process from mine tailings to its mineralization in sediment. The findings revealed that the Mo concentration in the aquatic environment significantly surpassed the environmental background levels. Specifically, the maximum exceedance of Mo in the water samples was recorded at 21600 times above the baseline. Additionally, the geoaccumulation index (Igeo) values in both sediments and tailings exceeded 5. The sediments collected from aquatic environments impacted by AMD in the East Qinling molybdenum mining area predominantly comprised schwertmannite minerals, characterized by distinctive "poly spheroid" and "hedgehog" morphologies, and a substantial amount of Mo was immobilized within the mineral structure. In mine tailings, molybdenum (Mo) predominantly exists in the oxidation state of Mo(VI), whereas in schwertmannite, both Mo(VI) and Mo(IV) are present. This indicates a significant change in the valence state of Mo during its migration from tailings to sediments. Moreover, leaching experiments demonstrated that Mo associated with schwertmannite can be re-released into the environment, the processes were significantly influenced by the mineralogical characteristics of schwertmannite. Specifically, schwertmannite with higher crystallinity was found to be more effective in immobilizing Mo.
