The Mercury Problem in Artisanal Gold Mining. Mercurybased artisanal and smallscale 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.

In many countries, elemental mercury is used in artisanal and smallscale gold mining. Mercury is mixed with goldcontaining materials, forming a mercurygold 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.

Reducing Mercury Impacts in SmallScale Gold Mining / 04 Oct 2017 Despite knowing full well the dangers of mercury, millions of smallscale gold miners across the globe continue to use the metal to separate gold from ore usually because they have little other choice.
However, mercury is also routinely used around the world in certain products, like batteries and lighting, and in industrial processes, including small scale gold mining. The miners combine the
