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 ...

Since most metals are present in ores as oxides or sulfides, the metal needs to be reduced to its metallic form. This can be accomplished through chemical means such as smelting or through electrolytic reduction, as in the case of aluminium. Geometallurgy combines the geologic sciences with extractive metallurgy and mining.

The copper ores are far more abundant than Native Copper, and are therefore the main source of copper nowadays. Even though, Native Copper is a sometimes mined as a minor ore of copper. Copper ranks second for as most-used metal in the world. The special properties of conductivity, malleability, resistance, and beauty make it so popular.

The less reactive metals are extracted from their ores by first converting the ore to metal oxide and then reducing the metal oxide to metal by heating it. Example: Cinnabar (HgS) is heated in air to form mercury (II) oxide. On heating the mercuric oxide to about 300 o C, the metal oxide decomposes to give the metal mercury.
