Metals that aren't very reactive are placed low in the reactivity series. These metals can be reduced to metals by heating alone. For example, Mercury is procured from its ore, cinnabar (HgS), by the process of heating. Copper can also be obtained from its sulphide ore (Cu2S) by heating. Metals more reactive than carbon, such as aluminium, are extracted by electrolysis, while metals less reactive than carbon, such as iron, may be extracted by reduction with carbon. As gold is so unreactive, it is found as the native metal and not as a compound. It does not need to be chemically separated.
