    • Drying of coal fines assisted by ceramic sorbents 

      Van Rensburg, M.J.; Le Roux, M.; Campbell, Q.P. (Springer, 2016)
      It is proposed to introduce contact sorption drying as a method to reduce the moisture content in coal fines. The aim of this study was to investigate the possibility of drying fine and ultra-fine coal using porous ceramic ...

    • Improved gold recovery by accelerated gravity separation 

      Waanders, F.B.; Campbell, Q.P. (Gecamin Publishers, 2014)
      This project was specifically aimed at using increased acceleration separation, as a method to optimize the recovery of gold in an ore body mainly consisting of hematite where the specific gravity of gold is much higher ...

    • Simulation of washability and liberation information from photographs 

      Dorland, H.C.; Campbell, Q.P.; Le Roux, M.; McMillan, K.; Dorland, M.I. (Springer, 2016)
      Imagine that a sample of coal could be crushed unlimited times to the same or different top size; a different washability would be obtained for each crushing experiment. Depending on the size and distribution of the raw ...

    • Using visual texture analysis to classify raw coal components 

      Van Vuuren, Pieter A.; Le Roux, M.; Venter, W.C.; Campbell, Q.P.; Dorland, H.C. (IEEE, 2015)
      Coal ore isn’t a uniform material. In order to optimize the coal liberation process it is necessary to classify a coal ore sample into its constituent components as quickly and cheaply possible. This paper investigates ...
