    • Air drying of fine coal in a fluidized bed 

      Le Roux, M.; Campbell, Q.P.; Van Rensburg, M.J.; Peters, E.S.; Stiglingh, C. (SAIMM, 2015)
      The demand for energy has continued to rise worldwide in line with population growth. The majority of South Africa’s electricity is supplied by coal-fired power stations. The amount of fine coal (-2 mm) generated at coal ...
    • Contact sorption: a method to reduce the moisture content of coal fines 

      Van Rensburg, M.J.; Le Roux, M.; Campbell, Q.P.; Peters, E.S. (Taylor & Francis, 2020)
      This paper introduces contact sorption with ceramic sorbents as a method to reduce the moisture content of coal fines produced by coal processing plants. The proposed method was tested on laboratory scale where ceramic ...
    • 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 ...
