\nCinnabar is a mineral with the chemical formula $\\text{HgS}$ (mercury(II) sulfide). It is the most common ore from which the element mercury ($\\text{Hg}$) is extracted. Historically, it was mined extensively, and its red color made it a valuable pigment (vermilion). Roasting cinnabar in air converts the mercury(II) sulfide to elemental mercury and sulfur dioxide:
\n$\\text{HgS(s)} + \\text{O}_2\\text{(g)} \\rightarrow \\text{Hg(g)} + \\text{SO}_2\\text{(g)}$
\n<\/section>\n
\n– Cinnabar is a mineral composed of mercury sulfide ($\\text{HgS}$).
\n– An ore is a natural occurrence of a rock or sediment which contains sufficient minerals with economically important elements, metals or gems.
\n– Cinnabar is the primary ore for the extraction of mercury.
\n<\/section>\n
\nOther common ores of the metals listed are:
\n– Zinc: Sphalerite ($\\text{ZnS}$), Calamine ($\\text{ZnCO}_3$).
\n– Copper: Chalcopyrite ($\\text{CuFeS}_2$), Malachite ($\\text{Cu}_2(\\text{CO}_3)(\\text{OH})_2$), Azurite ($\\text{Cu}_3(\\text{CO}_3)_2(\\text{OH})_2$).
\n– Lead: Galena ($\\text{PbS}$).
