HPGR or high-pressure grinding rolls have made broad advances into nonferrous metal mining. The technology is now widely viewed as a primary milling alternative, and there arc a number of large installations commissioned in recent years. After these developments, an HPGR based circuit configuration would often be the base case for certain ore types, such as very hard, abrasive ores. … Smaller scale beneficiation and concentration plants with a couple of hundred tonnes per hour capacity, as well as large concentrators like Cerro Verde, Mogalakwena, Boddington, Salobo, Sierra Gorda, and Karara have utilized high pressure grinding rolls (HPGR) technology and have operated successfully for more than a decade.
