Artisanal and Small-Scale 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.
