Uses: Mercury is amalgamated with gold to facilitate the recovery of gold from its ores. Mercury is used to make thermometers, diffusion pumps, barometers, mercury vapor lamps, mercury switches, pesticides, batteries, dental preparations, antifouling paints, pigments, and catalysts. Many of the salts and organic mercury compounds are important.
Sources: Mercury rarely occurs free in nature. It's chief ore is cinnabar, HgS. Mercury is obtained from cinnabar by heating the cinnabar in air and condensing the vapor.
