Magnetite ore is extracted using traditional open pit mining techniques, utilising drill and blast, and some of the world’s largest excavators and haul trucks. The open pit mine is currently over 2.5 km2 in area and will expand during the life of the mine to more than triple this size.
Our ore starts its concentrate processing journey within the pit itself. After mining, it passes through four of the biggest in-pit crushers ever installed in Australia. This reduces the ore to roughly the size of a house brick. It’s then transported by conveyors to the processing plant, also known as the concentrator area.
The relatively short 30km distance between the mine and the port at Cape Preston has reduced the need for investment in significant infrastructure to transport the ore.
Facts & FIGURES
- The largest haul truck weighs approximately 260 tonnes and can haul 340 tonnes.
- The largest excavator weighs close to 1,000 tonnes, with loading capacity of 4,500 tonnes of ore per hour.
- Four in-pit crushers from Germany with design capacity to crush 4,250 tonnes of ore per hour per unit.
- The conveyor carrying crushed ore from the mine to the concentrator area is about 1.7km long.
