• The Effect of Pre-Oxidation on the Reducibility of Chromite Using Hydrogen: A Preliminary Study 

      Davies, Jamey; Tangstad, Merete; Ringdalen, Eli; Beukes, Johan Paul; Bessarabov, Dmitri; du Preez, Stephanus Petrus (Peer reviewed; Journal article, 2022)
      The majority of ferrochrome (FeCr) is produced through the carbothermic reduction of chromite ore. In recent years, FeCr producers have been pressured to curve carbon emissions, necessitating the exploration of alternative ...
    • Mineralogical Sequence of Self-Healing Products in Cracked Marine Concrete 

      Danner, Tobias; Jakobsen, Ulla Hjorth; Geiker, Mette Rica (Journal article; Peer reviewed, 2019)
      Self-healing of cracked concrete beams after 25 years of marine exposure was investigated. The extent of self-healing and the chemical and mineralogical composition of the self-healing products were characterized, and ...
    • Reduction and Dissolution Behaviour of Manganese Slag in the Ferromanganese Process 

      Li, Xiang; Tang, Kai; Tangstad, Merete (Journal article; Peer reviewed, 2020)
      The reduction and liquidus behaviour of manganese slag with different basicities were studied in non-isothermal experiments in the temperature range of 1400–1500 °C. Certain amounts of quartz were added to Assmang ore ...
    • The use of hydrogen as a potential reductant in the chromite smelting industry 

      Davies, Jamey; Paktunc, Dogan; Ramos-Hernandez, José Juan; Tangstad, Merete; Ringdalen, Eli; Beukes, Johan P.; Bessarabov, Dmitri G.; Du Preez, Stephanus P. (Peer reviewed; Journal article, 2022)
      The chromium (Cr) content of stainless steel originates from recycled scrap and/or ferrochrome (FeCr), which is mainly produced by the carbothermic reduction of chromite ore. Ever-increasing pressure on FeCr producers to ...
