The Mining Process

The ore now goes through a threestage processing cycle to ensure the gold is economically recovered from the ore. 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.
