Mercury Ore
Mercury is extracted from cinnabar ores (HgS) by heating the ores in a current of air and collecting the vapor formed. The reaction for this extraction can be shown as: HgS + O2 → Hg + SO2. China has been the top producer of elemental mercury in the world with almost two-thirds global share of mercury ores [5].
