    Gold Nanoparticles. Nanoparticles are a fraction of the size of human hair and are less than 100 nm in diameter.One nm is equal to one one-billionth of a meter. Normal bulk gold is shiny, it is gold in color, it is inert, and it conducts electricity. "If, however, you shrink gold down to a nanoparticle, its properties change dramatically.

  • Artisanal and Small-Scale Gold Mining Without Mercury ...

    As water washes sediment down a sluice, gold particles sink and are captured by material covering the bottom of the sluice, often carpets. Sluices are usually inclined at 5 to 15 degree angle. As moving water travels down a sluice, it generates greater force and keeps gold particles from sinking easily.
