Why gold mines are adopting HPGRs to increase production and
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 goldAGICO CEMENT supplier cement roller press, high pressure grinding roll for raw materials grinding, roller press cement mill, high pressure grinding roller, Get your free quote now!
