Mercury Sulfide occurs in two forms, most easily characterized by their color:
The red oreCinnabar is the form in which mercury is most commonly found in nature
The black ore is less common. It is used in pigments.
An ore is a mineral deposit containing a metal or other valuable resource in economically viable concentrations. ... Cinnabar ( German Zinnober), sometimes written cinnabarite, is a name applied to red mercury(II) sulfide (HgS), or native vermilion, the common ore of mercury. ...
Mercury is found principally in the form of the orecinnabar (mercurysulfide) and can also be found in the uncombined state.
Mercury and mercury compounds were used from about the 15th century to the mid 20th century to cure syphilis.
Mercury salts released into the environment may frequently be converted by anaerobic bacteria into such compounds, which can then be carried through the food chain to humans as in the disaster at Minamata Bay, Japan Other micro organisms can convert methyl mercury compounds into the insoluble, and therefore harmless, mercurysulfide.
