Mercury is a metal which is used in several things such as in thermometers and other measuring tools.
The process of extraction of Mercury metal from its ore Cinnabar (HgS).
Most of the world's mercury is obtained from its main ore, cinnabar or vermillion with the chemical structure mercury sulphide (HgS). Cinnabar is usually found in a massive or granular form but can also occur as small crystals.

Heya friend here's your answer....
Cinnabar also known as HgS is termed as the mercury ore.
Mercury can be obtained from cinnabar by heating the cinnabar ore in a current of air and condensing the mercury vapour formed. Due to its relatively low boiling point mercury can be easily purified by vacuum distillation. The reaction of mercury sulphide with oxygen is shown below:
HgS + O2 = Hg + SO2
This process is also called Roasting. However Mercury can be obtained from other reactions too. For ex:
HgS + Fe = Hg + FeS
4HgS + 3 CaO = 4Hg + 3CaS + CaSO4
Hope this helps...
hey archit did u remember me!!!
