This unprecedented high price for gold meant that many large lowgrade ore deposits were now commercially viable mining propositions. Semi autogenous grinding (SAG) mills, because of their advantages in terms of capital and operating costs, were the natural choice for mines as their primary grinding mill option.
Copper Ball Mill Lining Felona Heavy Industries. Gold Copper Mine Ball Mill Rubber Lining A ball mill is a type of grinding mill which purpose is similar to the sag mill or other mining crushers These machines are used to grind or mix metals or raw materials for further processing Various materials are placed into the mill drum and rotated with the mined materials that are to be crushed.
G. Desch#234;nes, in Gold Ore Processing (Second Edition), 2016. Ultrafine Pyrrhotite Concentrate. Ultrafine grinding is used to liberate gold finely disseminated in metallic sulfides. KCGM is the first gold mine using ultrafine grinding followed by cyanidation (Ellis and Gao, 2002).The gold sulfide concentrate is grind with an IsaMill to a P 80 of 1012 m.

However, the SAG route is more powerintensive and, for very hard ores, comes with some process risk in predicting performance. More recently, a hybrid solution has become available in the form of high pressure grinding rolls (HPGRs), which can replace the third stage of crushing and also the SAG mill.
