  Hydraulic design of a thickened tailings gravity …

  The discharge platform is susceptible to abrasion when TT is discharged from the top of the platform, while a hydraulic design challenge is introduced when discharging by gravity from the bottom of the platform due to the rising tailings level as deposition progresses. The pressurised manifold considered feeds eight gravity lines into spigots.
