    • Adsorbent assisted drying of fine coal 

      Peters, Elmarie Sunette (North-West University (South Africa) , Potchefstroom Campus, 2016)
      Coal fines are generated by the increase in mechanization on coal mines, and have the ability to retain large amounts of moisture due to its inherently large surface areas (Reddick et al., 2007). The bulk of the moisture ...
    • A comparison between high airflow drying and adsorption assisted drying for the dewatering of fine coal 

      Van Rensburg, M.J. (North-West University (South Africa), 2019)
      Development in the fossil fuel sector should be an on-going process to promote sustainability, while reducing the environmental footprint. It is important to improve operations in the mining sector to ensure that coal is ...
    • Correlating laboratory and pilot scale reflux classification of fine coal 

      Smith, Izak Gerhardus Theron (2015)
      The search for efficient and economical ways to beneficiate fine coal remains an active research area. Recent developments have shown that the reflux classifier can successfully be used on Australian coals, and based on ...
    • Drying of fine coal using warm air in a dense medium fluidised bed 

      Van Rensburg, Martha Johanna (2014)
      Fluidised bed drying is currently receiving much attention as a dewatering option after the beneficiation of fine coal (defined in this study as between 1mm and 2mm particles). The aim of this study was to investigate the ...
