The design Malartic ore charateristics are similar in competency to the Cadia Project ore. The Cadia Project's 40 x 20 ft, 20 MW SAG mill treated approximately 48 kt/d, operating under similar conditions. Cadia operates (in SABC mode) with a SAG mill specific energy of around 8.5 to 9 kWh/t.

DetailsIn June 1998, the world's largest grinding mill, the 40 ft (12.2 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 (12.2 m ...
DetailsThe 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.

Concentrator 1 has a current throughput of about 23 Mt/a. Concentrator 2 was commissioned ...
DetailsThe biggest characteristic of the sag mill is that the crushing ratio is large. The particle size of the materials to be ground is 300 ~ 400mm, sometimes even larger, and the minimum particle size of the materials to be discharged can reach 0.1 mm. The calculation shows that the crushing ratio can reach 3000 ~ 4000, while the ball mill's ...

DetailsPublisher Summary. For the vast majority of ounces of gold produced, comminution costs in the form of power, grinding media, and liners represent the single largest cost category of milling. Since, semi-autogenous grinding (SAG) ball-mill circuits represent the single largest type of gold milling comminution circuits, the chapter …
DetailsSingle stage SAG Mills are very beneficial in reducing CAPEX for plants with a staged throughput approach. When future tonnage is to be increased, the SAG Mill can feed downstream ball milling to boost capacity. Fuller-Traylor SAG/AG Mills range in size from 4.3m through 12.2m in diameter with powers as high as 28,000 kW.
DetailsGold production in the June 2019 quarter was 6% higher than the prior quarter, driven by higher production from Cadia and Lihir. Cadia achieved a record annualised mill throughput rate of 31.7 million tonnes per annum (mtpa) for the quarter, contributing to Cadia achieving its highest ever gold and copper production annually and exceeding its
DetailsSAG mill liner development draws primarily on practical experience from SAG milling operations supported by computer-based modeling of charge motion in SAG mills and on established good design practice. Liner design needs to respond to the process aspects of mill liner action that are critical to good SAG mill performance, i.e., the impact …
