HPGR High Pressure Grinding Rolls

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.

KEYNOTE: HPGR in Gold Leach Applications – an Overview ...

Although HPGR’s major benefit to hydrometallurgy is its micro-fracturing of the rock matrix, it does generate some finer product sizes which are inherently beneficial for gold heap leaching. This fines generation effect does not constitute a problem for other leach applications, specifically heap leaching of copper ores.
