The Mercury Problem in Artisanal and Small-Scale Gold

Mercury-dependent artisanal and small-scale gold mining (ASGM) is the largest source of mercury pollution on Earth. In this practice, elemental mercury is used to extract gold from ore as an amalgam. The amalgam is typically isolated by hand and then heated-often with a torch or over a stove-to dist

The Mercury Problem in Artisanal and Small‐Scale Gold

2018-5-11  These mining activities largely take place in the so‐called “informal” economy in which participants operate unlicensed or without legal authorization—a reason why effective regulation of mercury emissions is extraordinarily difficult.11 Nevertheless, these artisanal miners contribute substantially to the local and global economy, generating approximately 15 to 25 % of the

The Mercury Problem in Artisanal and Small‐Scale Gold

2018-1-3  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.

Mercury Contamination Associated with Artisanal Gold

2021-10-13  Artisanal and small-scale gold mining (ASGM) is the largest source of mercury (Hg) emissions and releases worldwide. The breakdown of anthropogenic Hg emissions by sectors shows that the predominant source sector is ASGM that annually releases about 1220 Mg of Hg into the atmosphere, terrestrial and freshwater environments. Over the last 50 years, Hg has
