Artisanal and Small-Scale Gold Mining Without

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

Artisan And Small-Scale Gold Mining Without Mercury

Our vision is to enable small-scale gold miners to achieve the same gold recovery rates as large-scale miners but with a lower cost, scalable, mobile processing plant. Small-scale miners can find it difficult to operate profitably. In Australia alone, 85% of gold tenements are inactive. This trend can be reversed and they can now better afford to compete with the large-scale miners.
