While HPGRs are not typically used for small plants due to their high capital cost, in this case the coarse gold particles and their liberation characteristics at sizes above 1-2mm meant improved gold recovery from gravity separation could offset the higher costs. The HPGR was selected to tertiary crush the ore to under 4mm to maximize gravity recovery of coarse liberated gold bef
