How are the less reactive metals (which are quite low in the reactivity series) extracted? Explain with the help of an example.

Solution:

Heat alone is used to recover the less reactive metals by reducing their oxides.

When mercury (II) oxide is produced, for example, mercury (II) sulphide ore is roasted in the air. Mercury oxide is heated to 300°C and turns into mercury metal.
