Why gold mines are adopting HPGRs to increase production …
HPGRs are highly effective for heap leaching because the high pressure particles experience between the HPGR's tyres introduces 'micro-cracks' or fractures, which allow the leaching chemicals to effectively diffuse through the particles and liberate the gold ore. Research has indicated this can provide up to 10-11% additional gold ...

INSTRUCTIONS TO AUTHORS FOR THE PREPARATION
A second source of uneven feed to the HPGR can be segregation, where one side of the HPGR is mostly fed with coarser particles, while the other side receives more fines. Figure 3 shows a schematic illustration of feed segregation prior to the HPGR (Van der Meer & Maphosa, 2011).
Online prediction of pressing iron ore concentrates in an …
