Gold Mining With Mercury Poses Health Threats for Miles. May 28, 2020 The mercury binds to the gold to form an amalgam, which is then extracted by burning, creating gaseous mercury that enters the atmosphere. The rest of the mercury ends up dumped on the landscape, which is ravaged and eroded by the mining

The Mercury Problem in Artisanal and Small‐Scale

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.
