Fine Gold Recovery. Separating Placer Gold Particles

Recovering fine gold from black sands is one of the most challenging aspects of gold mining. While we are all hoping to find that once-in-a-lifetime gold nugget, the vast majority of gold that we find as prospectors is very small in size, ranging from gold flakes down to dust so small that it is nearly invisible. Extremely fine particles of gold like this can be very difficult to separate

what is electrostatics? Yahoo Answers

2007-2-1  Electrostatics is the study of stationary electric charges. For example, if you connect one end of a battery to a giant metal sphere and the other end to another nearby sphere, but no current flows because there is no circuit, electrostatics studies how the electric charge will be distributed on the spheres and what the voltage between the spheres will be at different points.

When lightning strikes rocks or sand, the passage of large currents can heat the sand so that it forms hollow or branching mineral structures called fulgurites, or petrified lightning. The longest recorded fulgurite is over 5 m long.
