    • Fine coal dewatering using high airflow 

      Le Roux, M.; Campbell, Q.P.; Van Rensburg, M.J. (Taylor & Francis, 2014)
      Fluidized bed drying is currently receiving much attention as a dewatering option after the beneficiation of fine coal. Apart from concerns about safety and combustion, the operating costs can be high if very high gas or ...
    • Large-scale design and testing of an improved fine coal dewatering system 

      Le Roux, M.; Campbell, Q.P.; Smit, W. (Southern African Institute of Mining and Metallurgy (SAIMM), 2012)
      Fine coal (-500 μm) is notoriously difficult to dewater. It is not uncommon for a dewatered product to have a moisture content as high as 30 per cent after vacuum filtration. This poses several handling and financial ...
    • Moisture adsorption and desorption characteristics of some South African coals 

      Campbell, Q.P.; Barnardo, M.D.; Bunt, J.R. (Southern African Institute of Mining and Metallurgy (SAIMM), 2013)
      The high final total moisture content of fine coal after mining and processing is one of the major reasons that this resource is not extensively used in subsequent power generation, combustion, or other conversion processes. ...
