Abstract Mercury-dependentartisanaland small-scale gold mining (ASGM) is the largestsource of mercury pollution on Earth. In this practice, elemental mercury is used to extract gold from ore as an amalgam. The amalgam is typically iso-lated by hand and then heated—often with atorch or over astove—todistill the mercury and isolate the gold.
