Mercury is a metal with special properties that give it a wide variety of applications. Most obviously, mercury is a liquid at room temperature and standard air pressure. It is this property that caused it to receive the name hydrargyrum, meaning “watery silver” in Greek, from which its symbol, Hg is derived. Just as water is an effective solvent of many substances because of its chemical composition, mercury’s atomic structure makes it an effective solvent of most metals. This, combined with its low boiling point, make it useful for extracting gold from ore in a process of amalgamation and distillation.

Hg / Mercury is used in Gold Mining to form gold-mercury amalgam with small pieces of gold in soil or sediments. This amalgam is then heated to vaporize the mercury and leave the gold behind. this process is common to artisanal and small-scale gold mining, which accounts for significant amount global mercury consumption.


  • Recover pieces of gold that is mixed in soil and sediments.
  • mercury and gold form an amalgam.
  • extracted by vaporizing the mercury and leaving behind the pure gold.
