    • The effect of particle size on the rate and depth of moisture evaporation from coal stockpiles 

      De Goede, J.; Muller, B.; Campbell, Q.P.; Le Roux, M.; De Klerk, C.B. Espag (SAIMM, 2016)
      Excessive amounts of moisture in product coal can influence the efficiency of downstream utilization processes due to a decreased calorific value and handling problems. Stockpiles can be used to decrease the moisture content ...
    • 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 ...

    • Moisture transport during contact sorption drying of coal fines 

      Van Rensburg, M.J.; Le Roux, M.; Campbell, Q.P.; Peters, E.S. (Taylor & Francis, 2020)
      Studies have shown that contact sorption drying is a feasible technique to dewater fine (+0.15mm–0.5mm) and ultra-fine (−0.15 mm) coal. The aim of this article is to further investigate the drying mechanism involved. It ...
