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.
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
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.
Jan 30, 2020· This followed two planned shutdowns and SAG mill motor maintenance at Cadia during the September quarter. ... Newcrest is also working to increase the capacity of Cadia Hill.
The design of the 12 m diameter SAG mill installed at the Cadia Hill Mine in New South Wales followed after two years of extensive laboratory and pilot plant testwork. The testwork showed the Cadia ores to be hard and competent necessitating the use of both a variable speed SAG mill .
To a more significant degree than in other comminution devices, SAG Mill Liner Design and Configuration can have a substantial effect mill performance. In general terms, lifter spacing and angle, grate open area and aperture size, and pulp lifter design and capacity must be considered.
