      Mukono, Tichaona; Gjøvik, Jonas Einan; Gaertner, Heiko; Wallin, Maria; Ringdalen, Eli; Tangstad, Merete (Peer reviewed; Journal article, 2021)
      Three pilot-scale experiments have been conducted at SINTEF/NTNU in a 440 kVA AC electric furnace to demonstrate the process operation, energy requirements and CO2 emissions in the production of high carbon ferromanganese ...
    • Valorization of SiMn Sludge for Production of Low-Phosphorus Ferroalloys 

      Wallin, Maria; Bugten, Andreas Voll; Tranell, Gabriella; Ekstrøm, Kai Erik (Journal article; Peer reviewed, 2021)
      The sludge generated by wet scrubbing the off-gas from a silicomanganese plant in Norway represents a significant loss in silicon and manganese values. This work seeks to extract these values in the production of ferroalloys ...
