Extraction of Metals

Extraction of metals. The process of extracting metal ores buried deep underground is called mining. The metal ores are found in the earth's crust in varying abundance. The extraction of metals from ores is what allows us to use the minerals in the ground. The ores are very different from the finished metals that we see in buildings and bridges.
