Mercury comes from several types of mineral deposits world wide, but the most common type of mineral is called cinnabar. Cinnabar is mercury chemically bound to sulfur, i.e. HgS. Heating this mineral causes the sulfur to combine with oxygen creating sulfur dioxide, SO2, as a gas. (The gas is now considered a pollutant.) What remains is the mercury. Although mercury is a relatively rare element, there are dozens of sites around the world where it is actively mined.
