Cadia Hill Sag Değirmeni

A two-stage grinding process forms a part of the comminution circuit. The grinding circuit comprises a 6.5MW SAG mill and 6.5MW 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.

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 grinding rolls (HPGR) product …

Summary: 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 …

The Cadia Hill Concentrator was commissioned in July 1998. The 40- foot diameter SAG mill was designed to treat 2065tph of monzonite ore at a ball charge of 8% volume, total …

A grinding mill model based on discrete element method (DEM) simulations is being developed at Outotec Oyj (Finland) to be used in mill design optimization. The model can be used for many purposes; one example is the selection of the lining and the size of the mill to meet the requirements of the clients. To validate the accuracy of the DEM ...

The Cadia gold copper system in Central West NSW is a world class gold copper porphyry system, of late Ordovician to early Silurian age (435-445 Ma). Pre-mining resources totalled 15 Moz Au and 1.9 Mt Cu. Significant known mineralisation in the system includes Cadia Hill, Cadia-Ridgeway, Cadia East, Cadia Far East, Cadia Quarry, and the

The Fimiston 10.97 m (36 ft) SAG mill uses twin wound rotor/gearbox/ pinion drives with variable speed achieved through CCV systems. The CCV ring motor (gearless) drive is used at Cadia (20 MW) and Olympic Dam (18 MW). It has been the industry standard for SAG mills above 13 MW capacity.

Residents are opposed a new tailings dam which is being built at the Ballarat goldmine at Mount Clear, saying it is unsafe to build it less than 400m from existing homes.

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.
