  • Enhanced Holland-Batt spline for describing spiral concentrator performance 
    Grobler, J.D.; Naude, Natasia; Zietsman, Johannes Hendrik (Elsevier, 2016-06)
    The Holland-Batt spline is well known when it comes to plotting spiral separation performance. The spline, which consists of a linear curve and power curve, has been successfully used to fit test work data that is presented ...
  • Gravity separator performance evaluation using Qemscan® particle mineral analysis 
    Grobler, J.D.; Bosman, Jeremy B. (Southern African Institute of Mining and Metallurgy, 2011-06)
    In a gravity separation device, particle shape, size and density all play a role. The combination of these determines where each individual particle reports to in the viscous fluid, where particle crowding (solids to ...
