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.
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.
In June 1998, the world''s largest grinding mill, the 40 ft ( m) diameter 20 MW Cadia gearless SAG mill, was commissioned. This was a leap of over 40% above the largest operating SAG mill. A significant saving in capital cost gave the incentive necessary for a single mill line at Cadia, resulting in the selection of the 40 ft ( m ...

The Cadia Hill deposit is a sheeted quartz vein system located almost entirely within the quartz monzonite porphyry phase of the Cadia Intrusive Suite. The predominant alteration is propylitic (chloriteepidote) with narrow domains of structurallycontrolled phyllic (sericitic) alteration. (PDF) Optimisation of the Cadia Hill SAG mill circuitl

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.
Cadia produces gold doré from a gravity circuit and goldrich copper concentrates from a flotation circuit at Cadia. The gold dore is then refined at the Perth Mint and concentrates are piped to a dewatering plant at nearby Blayney and sent by rail to Port Kembla in .
