    • Beneficiation of small South African coal using an air dense medium fluidized bed 

      Diedericks, E.S. (Peters); Le Roux, M.; Campbell, Q.P.; Hughes, N. (Taylor & Francis, 2020)
      This paper investigates the air dense medium fluidized bed (ADMFB) as a suitable dry beneficiation technique to upgrade +5.6 mm-13.2 mm South African coal. The separation efficiency of the ADMFB was assessed by determining ...

    • Destoning of fine coal in a fluidized bed 

      Le Roux, Marco; Campbell, Quentin; Langner, Danie (Springer, 2016)
      Water scarcity is driving the development of dry coal beneficiation processes. A lot of research has gone into the development of dry dense medium fluidized bed technology (DMFB), especially in China. However, these processes ...

    • Dry beneficiation of -13mm South African coal using an air dense medium fluidization bed 

      Diedericks, Elmarie Sunette (North-West University (South Africa)., 2023-10)
      Coal remains an important energy-resource base worldwide as it is considered abundant, affordable and reliable (WEC, 2022). South Africa’s national energy-resource base is dominated by coal; with coal-fired power stations ...

    • The dry beneficiation of duff coal in a dense medium fluidised bed 

      Langner, Daniël Johannes (North-West University (South Africa) , Potchefstroom Campus, 2016)
      Traditionally wet beneficiation is the predominant method in order to beneficiate coal due to its sharp separation efficiency; however large quantities of water are required in order to process the coal. Water scarcity, ...
