• Exergy relations in manganese production: Modelling the submerged arc furnace 

      Schanche, Trygve Lindahl (Master thesis, 2013)
      A model of the ferromanganese submerged arc furnace was purposed to yield valuable information for exergy calculations. A deeper understanding of at what point exergy is lost in the furnace might yield valuable information ...
    • Isothermal Reduction of Nchwaning Manganese Ore in CO/CO2/H2 Atmospheres 

      Schanche, Trygve Lindahl; Tangstad, Merete (Journal article, 2021)
      In the industrial production of manganese ferroalloys, incomplete pre-reduction of higher manganese- and iron oxides in the furnace causes an excess consumption of carbon and energy. Pre-treatment of the manganese raw ...
    • Prereduction of Nchwaning Ore in CO/CO2/H2 Gas Mixtures 

      Schanche, Trygve Lindahl; Tangstad, Merete (Peer reviewed; Journal article, 2021)
      Prereduction of Nchwaning manganese ore was investigated by isothermal reduction between 600 and 800 °C to optimize the conditions for industrial pretreatment of manganese ores. Experiments were conducted in CO/CO2 gas ...
