The extraction of mercury from cinnabar ore involves 2 steps :-
1. The concentrated mercury (II) sulphide ore (cinnabar ore) is roasted in air when mercury (II) oxide is formed :
2HgS + 3O2 ----> 2HgO + 2SO2
2. When this mercury oxide is heated to about 300 degree C, it decomposes to form mercury metal :
2HgO ----> 2Hg + O2
