At Boddington, ore containing copper and gold is crushed to a coarse size at the mine and then transported via conveyor to a process plant, where it is further crushed and then finely ground as a slurry. The ore is initially treated by successive stages of flotation resulting in a copper/gold concentrate containing approximately 15% to 20% copper.
