How do we extract minerals? U.S. Geological Survey

The rock is drilled and blasted, then moved to the surface by truck, belt conveyor, or elevator. Once at the surface, the material is sent to a mill to separate the ore from the waste rock. Lower grade metal ores found closer to the surface can be profitably mined using surface mining methods, which generally cost less than underground methods.

Extraction of Crude Metal from Concentrated Ore

This extraction of crude metal from the ore is done for extracting copper from copper sulphides, lead from lead sulphides and zinc from zinc sulphides. After this step, the oxide of the metals is then reduced by heating them in the presence of carbon. Carbon reduces the oxides to pure metals as it takes away oxygen to form carbon oxides.
