    Nov 16, 2020 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

    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
