What is cinnabar? how metals are extracted from cinnabar ? explain?

Answered by admin @ 16/08/2021

Cinnabar is the sulphide ore of mercury from which the mercury metal is extracted bye the processes of roasting and reduction. The sulphide or is heated in the presence of oxygen to convert it into oxide ore then further reduction gives the mercury metal and oxygen gas.

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...

HELLO DEAR,

cinnabar is a ore of the mercury

and mercury can be extracted by heating

the cinnabar in presence of air and by condensing the mercury the mercury vapour formed due to its low boiling point

The reaction of mercury sulphide with oxygen HgS + O2 → Hg + SO2

I HOPE ITS HELP YOU DEAR,

THANKS

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.
