Project Overview

  • Location: Western Australia
  • Industry: Mineral Sands Processing
  • Asset: Process Pond
The dredging system was designed to handle fine, low-settling materials while maintaining pond capacity and supporting ongoing processing operations.

Scope

  • Removal of slimes from secondary process pond
  • Management of fine, semi-fluid material with variable consistency
  • Operation within twin pond system with staged sediment separation
  • Water levels adjusted to optimise dredging and material movement
  • Transfer of slurry to drying area via client booster system

Outcome

  • A controlled removal approach efficiently managed the fine suspended solids without excessive disturbance
  • Improved management of slimes within the pond system
  • Enhanced performance of staged sediment separation
  • Stabilised material handling across variable slurry conditions
  • Reduced risk of long-term sediment build up
  • Maintained continuous operation during works
