Metals having low reactivity show little affinity for air, moisture, carbon dioxide or other non-metals present in nature. Such metals may remain in elemental or native (free) state in nature. Such metals are called "noble metals" as they show the least chemical reactivity. For example gold, silver, mercury and platinum occur in free state.

Metals low in the reactivity series are very unreactive. The oxides of these metals can be reduced to metals by heating alone. For example, Cinnabar (HgS) is an ore of mercury. When it is heated in air, it is first converted into mercuric oxide (HgO) then, mercuric oxide is reduced to mercury (Hg) on further heating.

dont bother with aluminium "recovery". look at the chart above and you will see aluminium right on top of the reactivity series (part of it). truth is, theoretically, you can "cement" aluminium with a more reactive metal, but this metal will be something like sodium, potassium or lithium. and not to mention, you cannot obviously precipitate it from aqueous solution, because …

Methods of Extraction. Depend on position of the metal in the reactivity series. Main methods are: Electrolytic Method: Used for metals high up in the reactivity series E.g. - Sodium and Potassium - Calcium and Magnesium - Aluminium. These metals occur in very stable ores; Reduction method: For less reactive metals. E.g. Iron, Zinc, and Copper.
