SELECTION OF HPGR TECHNOLOGY FOR THE CÔTÉ GOLD PROJECT
A typical SAG mill configuration, even with high ball loads, would not enable processing of this material in an energy-efficient manner. Testwork conducted at COREM using HPGR technology confirmed that this option provided metallurgical and economic advantages over SAG milling in a traditional flowsheet.

Energy savings with HPGR
In pellet feed application, HPGR is competing with dry ball mills, which consume more energy. Research conducted by the University of British Columbia found the introduction of a HPGR into Can Huckleberry gold mine’s mill circuit reduced power usage by 21% when grinding to a P80 of 160 μm, but that increased to 34% when milled down to 75 μm.

(HPGR) high pressure grinding rolls/rollers for cement
The HPGR (high pressure grinding rolls/rollers) is the core equipment of the high pressure grinding process. The machine reduces particles by compressing and crushing the feed between two counter rotating, parallel rollers with a small gap between them. This forces the rocks against each other and compresses the feed’s density to 80% of its solid […]

Effect of HPGR Breakage on Metallurgy – Minerals Engineering
After HPGR comminution, the gold particles are liberated as nuggets rather than flake-shape particles, thus less particle-shape related factors will affect the gravity separation performance. Also for sulfide associated gold recovery scenario, the gold is much easier to be recovered after treated by HPGR compared to ball mill grinding.
