Mercury is obtained from its sulphide ore called cinnabar, HgS which is actually mercury(ii) sulphide.
The following steps are involved in its extraction:
1. mercury ore is roasted
2HgS(s) + 3 o2 (g) -----> 2HgO (s ) + 2 SO2 (g)
2. when this mercury oxide is heated at about 300 degrees Celsius , it decomposes to form mercury metal.
2HgO (s) ------> 2Hg (l) + o2(g)
