HPGR for Heap Leach Circuits

August 16, 2022 HPGR
Due to the high pressure applied in the HPGR operation, the ore particles that pass through the machine are riddled with microcracks. Since ore particles tend to cleave along the grainlines where the precious metals lie within… these microcracks create tiny canals for the leach solution resulting in higher percent recovery of precious metals.
