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.
Artisanal and small-scale . SSM. gold miners Small-scale miners Some SSM communities continue to practice the same method of gold extraction developed by their forefathers, whereas other groups are innovative and try to improve working techniques to increase gold recovery rates. An excellent example of this is a group of SSM
