DESIGN OF THE 40 FOOT DIAMETER SAG MILL INSTALLED AT THE CADIA GOLD COPPER MINE By R. Dunne1, S. Morrell2, G. Lane4, W. Valery3 and S. Hart5 1Newcrest Mining Ltd, 2SMCC Pty Ltd, 3JKMRC, 4GRDMinproc Ltd, 5Newcrest Mining Ltd Cadia Hill Gold Mine, Australia ABSTRACT
For instance, at Lornex Mining, one of the most successful SAG installations, the ball load varies normally from 67% by volume of the mill; the ball makeup consists usually of 80% 4inch diameter balls and 20% 5inch diameter balls. The ratio of the larger balls is increased when the mill is processing hard ore and decreased with soft ore.
At the low level of collector dosage, increasing pH from 9 to 11 enhanced copper separation efficiency from 81% to 86% for IPETC and from 77% to 86% for SIPX. Results of ANOVA showed that the maximum copper separation efficiency (%) was obtained at the dosages of g/t SIPX, 7 g/t IPETC and 20 g/t MIBC at pH 11.

In this training module, we'll cover the workings of a semiautogenous grinding mill, or SAG mill, that's designed to be the first stage of a grinding circui...
For the mining industry, our semiautogenous (SAG) grinding mill uses a minimal ball charge in the range of 615 percent. It is primarily used in the gold, copper and platinum industries as well as in the lead, zinc, silver, and nickel industries. Autogenous (AG) grinding mills involve no grinding media as the ore itself acts as the grinding media.
The amount of copper in copper sandstones and slates varies from 1 to 6%, in sulfide coppernickel ores from to %, in copperpyrite ores from to 3%, and in copperporphyry ores from to %.

Working Principle of a SAG Mill. The rock and grinding media are placed in the mill and rotated, causing the grinding media to tumble and crush the rock into smaller pieces. The mill operates in a closed circuit with screens that size the ore and send it back to the mill for further grinding. The product from the mill is then sent to a cyclone ...
An aerial view of the Grasberg copper and gold mine in Papua, Indonesia (Photo: Business Wire) FPJO will construct a third semiautogenous grinding (SAG) mill adjacent to the existing milling facilities as the mining district continues to ramp up underground production primarily from the Deep Mill Level Zone and Grasberg Block Cave mines ...
