Location:

Queensland, 

Product:

BoreSaver Ultra C

Project Description:

Two of the deep dewatering bores for an open cut mine were badly affected by iron oxide deposits.

Keywords:

BoreSaver Ultra C, mine-site dewatering, iron oxide deposits. 

 

" The pumps are now working at maximum efficiency and the water output and flow has increased."

Two of the four main dewatering bores for an open-cut mine were badly affected by iron oxide deposits. These deposits caused overheating in four very large expensive pumps which resulted in them seizing every 10 days.

The mine uses four extraction wells to keep the mine dry and the groundwater is used for dust suppression and processing. The cascading bores are 400mm in diameter and 467m in depth. Fouling of the pumps is common with cascading bores because of elevated oxygen levels in the water which initiates oxidation of dissolved minerals and feeds aerobic bacteria present in the system.

BoreSaver Ultra C was mixed with water and then pumped through to the top of the pump. The iron dissolved into the solution, allowing the residues to be safely pumped away to waste.

The mine now has an on-going maintenance programme in place incorporating BoreSaver Ultra C. The pumps are now working at maximum efficiency and the water output and flow has increased. Pumps are lasting longer and there are fewer mechanical breakdowns.
