  • Why gold mines are adopting HPGRs to The Weir Group

    02/02/2021· HPGRs are highly effective for heap leaching because the high pressure particles experience between the HPGR’s tyres introduces ‘microcracks’ 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 1011% additional gold
