  • Artisanal and SmallScale Gold Mining Without Mercury

    Artisanal and SmallScale Gold Mining Without Mercury

    In many countries, elemental mercury is used in artisanal and small-scale gold mining. Mercury is mixed with gold-containing materials, forming a mercury-gold amalgam which is then heated, vaporizing the mercury to obtain the gold. This process can be very dangerous and lead to significant mercury exposure and health risks. In some jurisdictions, mercury use may be illegal or restricted in certain ways.
