    • Effect of (5%) CO2 on the Oxidation Rate During Cooling of Industrial Aluminum White Dross 

      Solem, Cathrine Kyung Won; Deledda, Stefano; Zedel, Hannes; Tranell, Maria Gabriella; Aune, Ragnhild Elizabeth (Peer reviewed; Journal article, 2023)
      Aluminum (Al) white dross is classified as hazardous waste and originates from the primary production of Al as a result of molten metal oxidation at an industrial scale. As the produced dross reduces the annual metallic ...

    • On the Direct Reduction Phenomena of Bauxite Ore Using H2 Gas in a Fixed Bed Reactor 

      Lazou, Adamantia; Eijk, Casper van der; Balomenos, Efthymios; Kolbeinsen, Leiv; Safarian, Jafar (Peer reviewed; Journal article, 2020)
      The Bayer Process is the dominant industrial method to produce alumina from bauxite ore. Due to the generation of large amounts of Bauxite Residue (red mud), an alternative method, called the Pedersen Process, is of our ...

    • Pilot-Scale Test of Flue Gas Recirculation for The Silicon Process 

      Andersen, Vegar; Solheim, Ingeborg; Gaertner, Heiko; Sægrov-Sorte, Bendik; Einarsrud, Kristian Etienne; Tranell, Maria Gabriella (Peer reviewed; Journal article, 2022)
      Flue gas recirculation (FGR) for the silicon process may facilitate increasing the CO2 concentration in the off-gas, which will be beneficial for potential future carbon capture. Lower oxygen concentration in the combustion ...

    • Recovery of Iron and Aluminum from Bauxite Residue by Carbothermic Reduction and Slag Leaching 

      Ekstrøm, Kai Erik; Bugten, Andreas Voll; Eijk, Casper van der; Lazou, Adamantia; Balomenos, E.; Tranell, Gabriella (Peer reviewed; Journal article, 2021)
      The recovery of major components of bauxite residue by carbothermic reduction at 1550–1750 °C and subsequent slag leaching in a Na3CO3(aq) solution is studied. Iron recovers primarily to pig-iron and lime is added to tune ...

    • Thermal De‑coating Pre‑treatment for Loose or Compacted Aluminum Scrap and Consequences for Salt‑Flux Recycling 

      Vallejo-Olivares, Alicia; Høgåsen, Solveig; Kvithyld, Anne; Tranell, Gabriella (Peer reviewed; Journal article, 2022)
      In aluminum recycling, thermal de-coating pre-treatments remove moisture and organic contamination before re-melting. If the scrap is compacted into bales or briquettes before the thermal treatment and re-melting processes, ...
