  • The Mercury Problem in Artisanal and SmallScale Gold Mining

    Mercurydependent artisanal and smallscale 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 heatedoften with a torch or over a stoveto distill the mercury and isolate the gold

  • The Mercury Problem in Artisanal and Small‐Scale Gold Mining

    Jan 03, 2018  These mining activities largely take place in the socalled “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 world's gold
