Artisanal and Small-Scale Gold Mining Without Mercury

2020-11-16  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 ...

Gold - IMPACT

Artisanal gold mining remains largely informal around the world and is prone to widespread corruption and violence. Due to its use as an alternative to paper currency, gold is often favoured for money laundering and illicit trade. It is a high-value, easy-to-transport mineral, which makes it an ideal target for armed groups. ...
