Nickel Recovery Process Pond Dredging – WA

Specialised dredging, desilting, and sludge removal for plastic lined process ponds and dams in mining and energy where conventional methods are ineffective.

Project Overview

A lined process pond adjacent to a nickel processing plant had accumulated dense nickel fines from repeated shutdown and overflow events, impacting return water quality and reducing overall pond performance.

Scope

  • Removal of accumulated nickel fines from lined process pond
  • Recovery and transfer of material back into plant operations
  • Traversing dredging operation across pond surface
  • Controlled sediment jetting to mobilise dense settled material
  • Operation without interruption to mill activities

Outcome

  • Recovery of nickel fines back into the processing circuit
  • Improved return water quality to the mill
  • Restored operational pond capacity
  • Maintained continuous plant operation during works
  • No damage to pond liner during dredging operations
