The first notable application for copper ore came in 1995 at the Cyprus Sierrita copper mine in the USA. However, on account of the extremely abrasive ore, no economical service lifetimes could be achieved for the grinding rolls. The breakthrough came in 2006 at the Cerro Verde copper ore project (Fig. 8) in Peru.
A SAG mill, also known as a semi-autogenous grinding mill, is one of the essential equipment used in copper ore mining. It plays a vital role in reducing large chunks of rock into smaller pieces to facilitate easier processing.
