Copper Mining: The commonest ore used in the extraction of copper is Chalcopyrite (CuFeS 2) also known as Copper Pyrites and other such sulphides. The percentage of copper in the actual ore is too low for direct extraction of copper to be viable. The concentration of ore is required and it is done by the Froth Flotation method. …

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 …
