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 ...
