ades of this century, when open pit mining, flo- tation concentration, and the reverberatory smelter were adapted to porphyry copper ores. With the exception of leaching-solvent extrac- tion-electrowinning, the basic methods of cop- per production have remained unchanged for 65 years. Moreover, six of the mines opened.

copper processing | Definition, History, & Facts | Britannica

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.
