      Senanu, Samuel; Ratvik, Arne Petter; Gudbrandsen, Henrik; Martinez, Ana Maria Cuellar; Støre, Anne; Gebarowski, Wojciech (Peer reviewed; Journal article, 2021)
      Concentrations of dissolved rare earth metal oxides, Nd2O3, and Pr2O3 or their mixtures in different fluoride electrolytes composed of NdF3, PrF3, and LiF at ca. 1040 °C were monitored using a graphite probe inserted into ...
    • Recycling of the Flue Gas from Aluminium Electrolysis Cells 

      Solheim, Asbjørn; Senanu, Samuel (The Minerals, Metals & Materials Series;2367-1181, Chapter; Peer reviewed, 2020)
      Recycling of the flue gas from aluminium reduction cells is a possible method for increasing the CO2 concentration, thereby enabling CO2 capture. The present paper represents a preliminary study concerning some of the ...
