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