    Gold deposits along the general gold path can be small or large, depending upon the size of the gold trap. The most important type of gold trap in river mining is called the “pay-streak”. Pay-streaks always form along the gold path where the river’s flow slows down on a large scale during a major flood storm

    Artisanal and Small-Scale Gold Mining Without Mercury | US

    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
