Leading power and automation technology group, ABB has recently won a $24 million order to supply a complete ore hoisting solution for Xstrata Zinc’s George Fisher Mine (GFM) located near Mount Isa in north-west Queensland, Australia.
Xstrata Zinc’s resources in and near Mount Isa including GFM are a major zinc resource base in the world with an estimated 600 million metric tons of ore and 36 million metric tons of contained zinc metal.
ABB’s ground-mounted friction hoist will carry ore from a depth of 1,135 metres and help increase GFM’s production by 30% per year by 2013. In addition to increasing production capacity at the mine, ABB’s integrated hoist solution will offer high levels of reliability and safety.
Reliable performance of the hoist is critical to the safety and financial success of the mine operation. ABB’s proven maintenance, lifecycle support services and expertise in delivering more than 600 new mine hoist systems worldwide were important factors in securing this contract.
As part of the order, ABB will design, supply and commission all the electrical and mechanical equipment for a new ground-mounted mine ore hoist system. Delivery is scheduled to be completed in the second half of 2013.
Highlights of ABB’s mine ore hoist system:
- Raises 600 metric tons of ore per hour from a depth of 1,135 metres at speeds of 16 metres per second
- State-of-the-art ACS 6000 medium voltage drive system will power a 9,000 kW synchronous motor to run the hoist
- Hoist design minimises impact on the surrounding power network
- Bottom dump ore skips with inspection platforms, rope deflection sheaves and a skip dumping system
- 800xA AC800M industrial controller to manage and control the entire system from the loading conveyors to the surface ore dump station
Axel Kuhr, country manager for ABB Australia attributes the order to their strong track record, commitment to serving the mining industry and unique position as a sole supplier of complete mine hoist systems.
