Impact of temperature on the leaching of sulphate, Co, Fe, Mn, Ni and Zn from the Ballangen tailings deposit, Norway: A laboratory column experiment
Lu, Jinmei; Walder, Ingar; Leiviskä, Tiina (Journal article; Tidsskriftartikkel; Peer reviewed, 2021-10-29)Temperature is an important factor affecting the leaching of contaminants from waste deposits, especially in the Nordic region where temperature change is more drastic than other areas. In this study, the impact of temperature variation in the leaching of sulphate, Co, Fe, Mn, Ni and Zn from the Ballangen tailings deposit, northern Norway, was investigated using a column leaching experiment. ... -
Vanadium removal from mining ditch water using commercial iron products and ferric groundwater treatment residual-based materials
Zhang, Ruichi; Lu, Jinmei; Dopson, Mark; Leiviskä, Tiina (Journal article; Tidsskriftartikkel; Peer reviewed, 2022-08-06)Removal of vanadium from liquid waste streams protects the environment from toxic vanadium species and promotes the recovery of the valuable metal. In this study, real mining ditch water was sampled from a closed vanadium mine (V–Fe–Ti oxide deposit, Finland) and used in sorption experiments at prevailing vanadium concentration (4.66–6.85 mg/L) and pH conditions (7.02–7.83). The high concentration ...
