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.
May 11, 2018· The Mercury Problem in Artisanal Gold Mining. Mercury‐based artisanal and small‐scale gold mining (ASGM) causes more mercury pollution than any other human activity.1 In this practice, mercury metal is used to extract gold from ore as a stable amalgam. The amalgam is then heated to evaporate the mercury and isolate the gold.
