"Modelling microbial transport in simulated low-grade heap bioleaching systems: The hydrodynamic dispersion model" - Elaine Govender-Opitz, Athanasios Kotsiopoulos, Christopher G. Bryan, Susan T.L. Harrison

  • Microbial concentration gradient and substrate availability drives transport.
  • Bulk advection-dispersion forces facilitate chemical and microbial transport.
  • Integration of population balance model improved estimation of mineral leach rates.
  • Ore-associated maximum specific growth rate significantly greater than that in PLS.
  • Successfully predicted changes in microbial concentration in phases within ore bed
