HPGR in Iron Ore Processing • Applied to iron ore industry mainly for regrinding of pellet feed to improve properties in the pelletising process • Over time has been applied to other iron ore processes to improve concentrates • Australia − Magnetite Karara − Vanadiferous Titaniferous Magnetite Future Mount Peake • South Africaread more
The present study evaluated aspects of microwave application to the iron ore concentrate fed to HPGR in a bench scale unit th e typical mill ing process to applications in a wide varietyread more
HPGR or highpressure 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 oresread more
application of HPGR would raise the grade cutoff for ore optimally going to the heap or dump leach Depending on the grade of ore and the recovery differential between milling and heap leaching and the metal price HPGR could even be expected to improve heap leaching economics to such an extent that in some cases the large capital investment in a millread more
