Reducing Mercury Pollution from Artisanal and Small

2020-10-14  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

Reducing global mercury pollution from small-scale

2021-1-3  Small-scale gold mining accounts for 37 % of global mercury pollution. Millions of poor people have to resort to this type of mining as the only way of sustaining their families. 2 A large part of the mercury used in the final step of gold extraction ends up as mm-sized droplets in dumps (tailings) from which mercury slowly evaporates to the

The Mercury Problem in Artisanal and Small-Scale

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 Mercury Problem in Artisanal and Small‐Scale

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.

GOLD: Addressing Mercury Pollution from Artisanal

2016-12-6  The GEF Council recently approved, at the October 2016 meeting, a global program to address "The Global Opportunities for Long-term Development "GOLD" in the Artisanal Scale Gold Mining (ASGM) sector, including provisions to address mercury pollution from the sector. The GEF GOLD program has strong private sector engagement, including major jewelers, electronics manufacturers,

River transport of mercury from artisanal and small

Artisanal and small-scale gold mining (ASGM) is a major contributor to deforestation and the largest anthropogenic source of atmospheric mercury worldwide. Despite significant information on the direct health impacts of mercury to ASGM miners, the impact of mercury

Artisanal and Small-Scale Gold Mining Without

Many artisanal and small-scale miners are achieving high rates of gold recovery without mercury, benefiting their health, the health of their communities, and the environment. On this page, we summarize some of the techniques in mercury-free artisanal and small-scale gold mining.
