Mercury, commonly known as "mercury", is a rare element in the earth's crust. A very small amount of mercury in nature exists in pure metal state and is the only liquid metal. Cinnabar, mercuric chloride, mercuric thioantimonate and other minerals related to cinnabar are the most common mercury deposits.
50% of the world's mercury comes from Spain and Italy, and the others are mainly Slovenia, Russia and North America. After cinnabar is heated in flowing air, mercury can be reduced and condensed after the temperature is lowered, which is the most important way to produce mercury.
Mercury is the only metal element that is liquid at room temperature. In nature, most mercury combines with sulfur to form mercury sulfide (HgS), also known as "Cinnabar" or "cinnabar", which is widely distributed in the surface layer of the earth's crust. Cinnabar and its polycrystalline Cinnabar are the main mercury-bearing ore sources. With the evolution of nature, various environmental factors may contain mercury, forming the natural background of mercury.

Mercury removal method
Due to the great harm of mercury pollution, all countries have formulated reasonable and effective mercury removal methods. At present, it is more effective to use an innovative patented chemical formula to effectively remove mercury through simple chemical reaction, and its basic component is a natural inorganic compound.
It is easy to be repaired with metal compounds, which have adsorption capacity for mercury. It is produced by natural chemical reaction and keeps low energy consumption in the production process.
The most effective way to remove mercury from coal combustion gas is to add a fine powder material to coal combustion gas. This substance interacts with gaseous mercury to remove it from coal gas, and mercury-containing particles are captured by the particle capture system of power plant.
Novenda (preparation of silicate) is a patented mercury removal agent, which can effectively remove mercury produced by coal coke plant. This product has the advantages of economy and environmental protection, and cannot be used with other mercury removal products.
