    • Dry beneficiation of fine coal using a fluidized dense medium bed 

      Terblanche, Andre Nardus (2013)
      Beneficiation of fine coal (+500 μm –2000 μm) is a worldwide problem in the mining industry, especially dry beneficiation of fine coal. Coal beneficiation can be divided primarily into two methods, namely wet- and dry ...
    • 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 ...
    • Recuperation of H2SO4 in the hybrid sulphur process using pervaporation 

      Van Rhyn, Marco. (North-West University, 2012)
      In this experimental study the sorption and pervaporation characteristics of commercial Nafion–117 and Nafion–212 membranes with mixtures of water (H2O) and sulfuric acid (H2SO4) were investigated. During experimentation ...
    • SO2 and O2 separation by using ionic liquid absorption 

      Rabie, Samuel Liversage (North-West University, 2012)
      In order to reduce the amount of pollution that is generated by burning fossil fuels alternative energy sources should be explored. Hydrogen has been identified as the most promising replacement for fossil fuels and can ...
    • Water transport mechanisms in coal stockpiles 

      Espag, Chané Bernadette (North-West University (South Africa) , Potchefstroom Campus, 2015)
      One of the key indicators of coal product quality is the moisture content. Excess moisture can have a negative effect as it results in handling problems and a reduction in coal value by decreasing the heating value. The ...
    • Winnowing as a dry separation method for fine coal 

      Morgan, L. (North-West University (South Africa), 2020)
      Dry coal processing is fast becoming favoured as a fine coal beneficiation technique. The decline in suitable good-quality coal, as well as the ongoing decrease in usable process water, makes dry beneficiation of the fine ...
