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.
