  2. A little Bit of History • Element #80 • Hydrargyrum • Dates back to 1500 BC • Used as pigments and vaccinations

  3. Characteristics • Liquid at room temp • Rarely found in nature • Mined as Cinnabar • Low melting / freezing point’s • Color determines grade of ore • Can be transformed into other forms of mercury

  4. Geologic Formations • Found in two places • Near volcanic margins • Felsic intrusive • Hot springs • Hydrothermal source

  5. Production • Percentage in crust • China • Kyrgyzstan • Rest of the world

  6. Extraction Process • Hot springs • Open pit / Underground • Sulfur bank mine CA • Near volcanic margins • Underground

  7. Industrial Uses • Power generation • Chemical plants • Artisanal mining

  8. Commercial / Practical Uses • Fish consumption • Thermometers • Barometers • Fluorescent lamps • Vaccinations • Hat making industry 1800’s

  9. Different Forms of Mercury • Bituminous coal • Key ingredient • Elemental mercury • Ionic reduction • Oxidized mercury • Smoke stacks • Methylmercury • Final product

  10. Geoplolitics • EPA measures • Clean Air Act 1993 • Safe Drinking Water Act • Emission Standards

  11. Some Odd Stuff Wouldn’t You Say??? • Alchemists thought of mercury as the father to all elements • Only three other elements are liquid at room temp • Cesium, Gallium, and Rubidium

  12. References • http://en.wikipedia.org/wiki/Mercury_(element)#Etymology_and_history • http://www.chemicalelements.com/elements/hg.html • http://www.naturalnews.com/016544.html# • And 28 others that wouldn’t fit
