• Bridging the Science-Policy Gap on Artisanal Gold Mining

    It is estimated that over 45,000 people take part in artisanal gold mining in this region. In their quest for gold, miners emit an estimated 30-40 tons of mercury into the environment every year, destroy an estimated 4,437 hectares of forest and load enormous quantities of sediment into the river.

    Aug 30, 2015In developing countries, this process is still popular for artisanal mining. The method involves amalgamating gold ore with mercury metal. The gold metal is melted into the mercury, while the impurities are separated. The gold-mercury amalgam is then heated to a high temperature, where the mercury evaporates, and pure gold is left behind.

    In mines, mercury is used to recover minute pieces of gold that is mixed in soil and sediments. Mercury and gold settle and combine together to form an amalgam. Gold is then extracted by vaporizing the mercury. The artisanal small-scale gold mining (ASGM) sector exposes miners to toxic mercury when they use the chemical to extract gold from ore.
