Artisanal mining - Wikipedia

Artisanal mining operations often cut down trees to clear space for their camps, and it is common for miners to hunt, fish, and collect other forest resources for food and medicine, or as a way to supplement their income. Mercury and other dangerous chemicals, such as cyanide, are commonly used in artisanal gold mining.

Artisanal and Small-Scale Gold Mining Without Mercury

In many countries, elemental mercury is used in artisanal and small-scale gold mining. Mercury is mixed with gold-containing materials, forming a mercury-gold 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.
