Reducing Mercury Pollution from Artisanal and Small-Scale ...

A major source of air pollution from mercury, artisanal and small-scale gold mining releases approximately 400 metric tons of airborne elemental mercury each year. Located in over 55 countries, small scale gold buying and refining facilities (commonly referred to as “Gold Shops”) are an important part of this production process, and are a major cause of air pollution from mercury.

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 distill the mercury and isolate the gold.

The Mercury Problem in Artisanal and Small‐Scale Gold

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.

Gold and mercury: A lethal mix - Ecocycle

Artisanal gold miners, often poor and operating illegally, use mercury to separate small amounts of gold from crushed rock. The mercury-gold mix is then heated over open fires to vapourise the mercury, leaving behind pure gold. This dangerous method of small-scale gold recovery is happening right now in many countries, including Papua New Guinea.
