Of the three flotation circuits, the Sulphide circuit has the highest recovery (>90%) due to the simple copper mineralization, with ~90% of the copper occurring in chalcopyrite. In the Mixed ore, chalcopyrite hosts ~35% of the copper in the feed, and in the Oxide ore this proportion is normally less than 20%. In the

For lower-grade deposits located near the surface, the open-pit method is the most practical for the mining of large tonnages of material. Large track-mounted drills prepare the ore for blasting, and the broken ore is hauled to the ore-dressing plant by truck (at up to 150 tons per load) or conveyor. In underground mining, vertical shafts are sunk well over 1,000 metres (3,300 feet) …
