Dec 10, 2018 Artisanal and small-scale gold mining (ASGM) in the Amazonian countries has undergone important technological improvements in recent decades. Nevertheless, this type of mining is largely associated with the use of rudimentary, low-tech and often manual methods, and inefficient gold recovery ( Hilson and Van Der Vorst, 2002, Veiga et al., 2014a ).

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 risksget price
