The contract: Dry stack tailings
Bis provides major tailings management and operational handling services for Karara Mining at this site. Central to the contract is the management of the Tailings Storage Facility (TSF) mobile conveyer stacking system, which Bis currently owns, operates and maintains.
The TSF is unique in Australia and operates 24 hours a day, 7 days a week, and is supported by Bis’ fleet of specialised earthmoving equipment. Bis was contracted to complete this work on an initial 15-year term, and currently moves approximately 9 million tonnes per annum (mtpa) of dry stack tailings for this customer.
As the tailings are stacked, the mobile TSF is relocated and expanded in line with the company’s tailings management plan. It is currently greater than 2km in length.
