What is the process of extracting metal from ore called?
Mining is the extraction of valuable minerals or other geological materials from the Earth, usually from an ore body, lode, vein, seam, reef, Both iron and copper can be extracted from the ore by heating with carbon. However, iron is a more reactive metal than copper. It is therefore a little harder to extract it from its ore.
