A rock breakage test has been developed that can help predict autogenous (AG) and semi-autogenous (SAG) mill performance in situations where only limited quantities of rock samples are available. The test was originally developed to make use of quartered (slivered) core but whole core, half core and lump material can also be used. …

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. The 40-foot (40') SAG mill now receives a feed of predominantly high pressure …

1.. IntroductionIt is generally recognised that the most accurate means for predicting the specific energy of an autogenous (AG)/semi-autogenous (SAG) mill circuit is to pilot the circuit using a 6 ′ × 2 ′ mill (Mosher and Bigg, 2001).However, one of the major drawbacks of this approach is that a relatively large sample is required to do so.

The design of the 40-foot diameter SAG mill installed at the Cadia Gold Mine, New South Wales Australia, followed after two years of extensive laboratory and pilot plant testwork. This showed the Cadia ores to be hard and competent necessitating the use of both a variable speed mill drive and pebble crushing. The grinding power requirements were …
Increasing the size of the mills, however, meant that Cadia would need to use mills of unproven design {40 ft x 20 ft (12.2 m x 6.1 m) SAG mill and 22 ft x 33.5 ft (6.7 m x 10.2 m) ball mills}. There was considerable concern about taking this step, as many saw this as a risky option in the Cadia Feasibility Study performed by Fluor Daniel-Davy.
