    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.
