HPGR or high-pressure grinding rolls have made extensive progress in non-ferrous metal mining. The technology is now widely seen as an alternative to primary milling, with a number of large units coming into use in recent years. Following these developments, HPGR-based circuit configurations are often the base case for certain ore types, such as very hard abrasive ores.
