A dry washer is a piece of equipment that is used to separate gold from sand with pulsations of air coming up through a porous cloth medium. This allows the gold to settle downward and get caught. It is the gold prospecting equipment of choice in dry desert areas. The vibrations and flow of air replace the function of water in the normal sluice ...

The inductor of the above tank circuit forms the detector of the metal detector (a large coil of wire). When metallic material approaches the center of the inductor (the detector coil), it enters the magnetic field created by the inductor. This changes the magnetic permeability of the inductor's core, causing the inductance to change. The ...
