Artisanal and Small Scale Gold Mining & Mercury • Despite having various uses, mercury in Tanzania is mostly used in the mining industry by artisanal gold miners (ASGM). • Despite that the use of Mercury for ASGM is legal, most of it is obtained through illegal means (thorough Kenya, South Africa and Zimbabwe).

The artisanal small-scale gold mining (ASGM) sector exposes miners to toxic mercury when they use the chemical to extract gold from ore. However, with the right policies and market incentives, ASGM presents an opportunity to fight mercury use and contamination, protecting miners' health and the environment at the same time.

Mercury is commonly used in artisanal and small-scale gold mining to extract gold from ore by generating a mercury-gold amalgam and heating it to vaporize the mercury and obtain the gold. This process releases ∼ 1350 t yr − 1 of mercury into the global environment, making artisanal mining the largest source of anthropogenic …
