ore is treated using a two-stage crushing process, followed by a two-stage grinding circuit that consists of a semi-autogenous grinding mill and a ball mill. most of the ground ore is fed to a gravity circuit that recovers about two-thirds of the gold, which is then smelted on site to form doré bars.,the mining process - oceanagold,stage 1: crushing and grinding. ore stockpiled from underground and open pit mines is fed into the primary crusher at the process plant. the jaws inside crush the rock down to fit through the 125mm gap at the bottom. crushed rock then travels to the mill.
