Gold mining

Historically, mercury was used extensively in placer gold mining in order to form mercury-gold amalgam with smaller gold particles, and thereby increase the gold recovery rat Large-scale use of mercury stopped in the 1960s However, mercury is still used in artisanal and small-scale gold mining (ASGM), often clandestine, gold prospecting...

Artisanal and Small

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...
