    • Column leaching heavy metal from tailings following simulated climate change in the Arctic area of Norway 

      Fu, Shuai; Lu, Jinmei (Journal article; Tidsskriftartikkel; Peer reviewed, 2018)
      This study aimed to assess how the current climate change perspective, with various air temperature (4°C, 10°C, 14°C and 18°C) affected metal releasing from tailings. Heavy metals pollution from tailings leaching are of increasing concern. Column leaching experiment was conducted for 15 weeks to a series of tailings with 20 mm/week water leaching four temperature situations. Leachate chemical physics ...
    • Column leaching test on oxidized and non-oxidized tailings in northern Norway 

      Fu, Shuai; Lu, Jinmei (Journal article; Peer reviewed, 2018)
      Column leaching test was applied for oxide and non-oxide tailings in the Arctic area. Physico-chemical parameters (pH, pe: potential ecolotric, conductivity, TDS: Total dissolved solids, SO4 2−, salinity, Ni, Co, Zn and Mn) were measured to identified the effect of oxidized degree on heavy metals leaching from tailings. Results showed that oxidized tailings contained higher levels of Co and Ni, and ...
    • Effect of temperature on the leaching of heavy metals from nickel mine tailings in the arctic area, Norway 

      Fu, Shuai; Lu, Jinmei; Walder, Ingar; Wu, Daishe (Journal article; Tidsskriftartikkel; Peer reviewed, 2023)
      The leaching of heavy metals from tailings deposit due to the oxidation of sulphidic tailings and formation of acidic leachate is considered a high risk to the surrounding environment. Temperature plays an important role in the leaching of heavy metals from tailings in changing acid-based environment, especially in the Arctic area. To investigate how the temperature variation affected metal release ...
    • Investigation on heavy metals pollution of municipal refuse leachate from Tromsø landfill, Northern Norway 

      Fu, Shuai; Lu, Jinmei; Yuan, Fuqing (Journal article; Tidsskriftartikkel; Peer reviewed, 2019)
      To investigate the heavy metal pollution in leachate from sanitary landfill site of municipal solid waste, a survey was conducted in Tromsø, Northern Norway. Results shows that contents of heavy metals in landfill leachate follow the order Mn>Zn>Ni>Cu>Cr>As>Pb>Cd>Hg, and the order of the risk of different heavy metals is: Mn>Ni>As>Zn>Cr>Pb>Cd>Hg>Cu. The concentrations of Mn and Ni in landfill leachate ...
    • Multivariate analysis of Co, Fe and Ni leaching from tailings following simulated temperature change 

      Fu, Shuai; Lu, Jinmei; Yuan, Fuqing (Journal article; Peer reviewed, 2018)
      A series of column leaching experiments were performed to understand the leaching behavior of Co, Fe and Ni in Ballangen mine tailings. Multivariate statistical approaches to evaluate potential risk variations in leachate quality and identifies temperature effects on their leaching behavior. Results from column leaching test indicated that the mobility of showed higher temperature may encourage ...
    • Temperature-driven variation in the removal of heavy metals from contaminated tailings leaching in northern Norway 

      Fu, Shuai; Lu, Jinmei (Journal article; Tidsskriftartikkel; Peer reviewed, 2019-01-31)
      High amounts of tailings with a low recycling rate are generated during mining and smelting processes, and a lot of environmental problems were caused by heavy metal leaching from tailings. Temperature is a key point in heavy metals leaching, and knowing the effects of temperature on tailings leaching is useful for tailings management. A small-scale batch leaching experiment was conducted at different ...
