For instance, the Cadia Hill plant operating costs are approximately /t due to the coarse grind size, simple plant and low power cost. Conversely, a 1 Mt ... Typically, a SAG mill based circuit (P80 of 106 to 150 um) has media costs of around A1/t. Providing the .
foot SAG mill at the Cadia Hill Mine in Australia. While the details vary, there is a theme that links these projects – careful development and analysis, timely results and ultimately the delivery of reliable, efficient gearless drives. Since 1998, Siemens has been providing gearless drive systems for 40foot SAG mills.
gold and 200,000 tonnes of copper concentrate per annum. The Cadia Hill grinding circuit liner design has been the subject of much design effort over the past 8 years (Hart et al, 2001). The Cadia SAG mill, commissioned in 1998 is 40 feet in diameter and 22 feet long with an installed capacity of 20MW. It is supported by 2 ball mills each 22 ...
A twostage grinding process forms a part of the comminution circuit. The grinding circuit comprises a SAG mill and ball mill. Using similar processes to the adjacent Cadia Hill concentrator, gold and copper are recovered in a conventional floatation circuit to produce a copper concentrate containing elevated gold levels.

Some dry autogenous mills operating in Canada are m in diameter and m in length. These are known as Aerofall mills. The Cadia Hill (Australia) wet SAG mill is m in diameter with a 20 MW motor and in 2004 was the largest diameter mill in operation in the world.
The model of the Cadia Hill SAG mill was based and derived from the pilot plant SAG (12% balls)/recycle crusher surveys. These were part of the second pilot campaign and were runs with two different load volumes of approximately 21% and 31%. The data from these tests were used to fit
The work led on to foundation analysis work at North Parkes and then Cadia Hill in 1996. The analysis of the Cadia SAG and ball mill foundations were critical in the resolution of the stator vibration problem that arose during the commissioning of the 40 ft SAG mill in 1998.
14th AusIMM Mill Operators'' Conference 2018, 2931 August, Brisbane. ABSTRACT. The Concentrator 1 plant at Cadia transitioned from Cadia Hill open pit to the Cadia East block cave ore body in 2013. As a result of this change, major plant upgrades were required to achieve the desired throughput while treating more competent ore.
