chemical process of 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.
