The high pressure of HPGR's "bed-breakage" creates micro-cracks in the ore, promoting improved mineral recovery at coarser size fractions. This means less leaching acid is required and percolation periods are shortened, reducing costs and maximising recovery in less time. In the diamond industry, the HPGR acts as a selective grinder ...
