Question

What is cinnabar how is metal extracted from cinnabar explain briefly

Answer 1

Cinnabar refers to the common bright scarlet to brick-red form of mercury(II) sulfide, formula HgS, that is the most common source ore for refining elemental mercury, and is the historic source for the brilliant red or scarlet pigment termed vermilion and associated red mercury pigments.

To produce liquid mercury (quicksilver), crushed cinnabar ore is roasted in rotary furnaces. Pure mercury separates from sulfur in this process and easily evaporates. A condensing column is used to collect the liquid metal, which is most often shipped in iron flasks.

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...
