Alternatives to mercury use in small-scale gold mining
38.92. Tuesday, 2 January 2024. In Zimbabwe elemental mercury is used in artisanal and small-scale gold mining. Mercury is mixed with gold-containing materials, resulting in the formation of the mercury-gold amalgam which is then heated, vaporizing the mercury to obtain the gold. This process is very dangerous and can lead to significant ...
