Where is mercury found in the Earth?
The occurrence of mercury is not very common. It is present in crust of the Earth on an average of 0.08 gram, making 0.003 ounce per ton of the rock. Mercury is rarely present in free, pure form and its principally present in the form of the red sulfide, termed as cinnabar (HgS). Naturally, mercury is present near hot springs and volcanoes in isolated drops or in larger fluid masses. Eruption of volcanoes can lead to 4-6 times increase in the atmospheric presence of volcanoes [3]. Around 2/3 rd of supply of mercury in the world comes from China, and Chile and Kyrgyzstan make up the rest [4]. Mercury is often obtained as a by-product during the process of gold mining. Some other natural alloys of mercury have also been found, including potarite (with palladium) gold amalgam and moschellandsbergite (with silver), but these are extremely rare.

What are the two types of mercury?
There are two types of compounds of mercury: organic and inorganic. The most common organic compound is methyl mercury, which is extremely toxic. There are no industrial uses for methyl mercury and it is formed naturally in the environment via the methylation of the inorganic mercury ion. The most common inorganic compound is mercuric chloride, HgCl 2, which is used in photography, laxatives, disinfectants, fungicides, and more. However, its use has declined in many products so it is mainly found in disinfectants and pesticides. As previously mentioned, mercury exists naturally as mercury sulfide (Cinnabar) which creates the red pigment vermilion.
How is mercury extracted?
As previously stated, mercury is extracted from the mineral cinnabar through the purification process of distillation. This is done by first crushing the ore. It is then heated in a furnace which vaporizes the element. This vapor is then collected and condensed into liquid form. Vaporized mercury is extremely toxic and can wreak havoc on the respiratory system, so it is important to do so with caution.
