Requiring less process stages, an HPGR significantly reduces overall circuit energy consumption, grinding media consumption and wear cost. The Enduron ® HPGR featuring KHD* technology can be utilised in a wide variety of minerals and size reduction duties, from coarse crushing for heap leaching through to iron ore pellet feed grinding.

HPGR treated minerals show better leaching performance, because the micro-cracks increase the particle contact surface for the leaching liquid. Also, flotation efficiency is further enhanced through the use of HPGR comminution. Grinding of material in HPGRs has proven to be more cost efficient as compared to conventional mills and crushers.

The typical application of HPGR in heap leaching will be replacing the conventional tertiary crusher. With the larger, super HPGR systems of the future, additional metallurgical options exist, shifting more of the crushing load to the HPGR. When processing leachable ores through an HPGR, micro-cracks are created.
