    • Aqueous solubility of Cr(VI) compounds in ferrochrome bag filter dust and the implications thereof 

      Du Preez, S.P.; Beukes, J.P.; Van Dalen, W.P.J.; Van Zyl, P.G.; Loock-Hattingh, M.M. (WRC, 2017)
      The production of ferrochrome (FeCr) is a reducing process. However, it is impossible to completely exclude oxygen from all of the high-temperature production process steps, which may lead to unintentional formation of ...
    • Cr(VI) contamination of aqueous systems 

      Loock-Hattingh, Monique Marié (North-West University (South Africa) , Potchefstroom Campus, 2016)
      Hexavalent chromium, i.e. Cr(VI), is a potential pollutant species formed due to anthropogenic processes, e.g. leather tanning, Cr(VI) chemical production, stainless steel manufacturing and ferrochrome production. Cr(VI) ...
    • Unique challenges of clay binders in a pelletised chromite pre–reduction process : a case study 

      Kleynhans, Ernst Lodewyk Johannes (North-West University, 2011)
      As a result of increasing cost, efficiency and environmental pressures ferrochrome producers strive towards lower overall energy consumption. Increases in local electricity prices have placed particular pressure on South ...
