Producing Mercury (Hg)

Hg: Mercury

This element is known from ancient ages.

Abundance: 0.08ppm(in the earth's crust)

Method 1

Bake cinnabar with calcium oxide.

Calcium oxide prevents Hg from recombining to S.

4HgS + 4CaO 4Hg + 3CaS + CaSO4

Method 2

Bake cinnabar, although it is not efficient.

HgS Hg + SO2
