    • Coal-based reducing agents in ferroalloys and silicon production 

      Tangstad, Merete; Beukes, Johan Paul; Steenkamp, Joalet; Ringdalen, Eli (Elsevier, 2019)
      Manganese, chromium, and silicon ferroalloys are typical examples of alloys that are produced using carbon materials to remove oxygen from the raw materials. A majority of such alloys are currently produced in electric ...

    • Electrical resistivity of carbonaceous bed material at high temperature 

      Surup, Gerrit Ralf; Chaldien, Annah; Beukes, Johan Paul; Pedersen, Tommy Andre; Tangstad, Merete (Springer Verlag, 2020)
      This study reports the effect of high-temperature treatment on the electrical properties of charcoal, coal, and coke. The electrical resistivity of industrial charcoal samples used as a reducing agent in electric arc ...
