Hi mate
Here is ur answer
CINNABAR is the main ore of mercury
Mercury is obtained from its sulphide ore called cinnabar, HgS which is actually mercury(ii) sulphide
.when this mercury oxide is heated at about 300 degrees Celsius , it decomposes to form mercury metal. Mercury is obtained from its sulphide ore called cinnabar, HgS which is actually mercury.
I hope this will help you...

Answer:
Mercuric Sulphide or Cinnabar ore is generally obtained from mercury
Mercuric Sulphide is strongly heated in the presence of Oxygen (roasting) to form Mercuric Oxide. Then it is heated with limited oxygen to obtain Mercury.
Chemical Equation
2HgS + 3O₂ ------> 2HgO + 2SO₂
2HgO -----> 2Hg + O₂
