The particles of gold can be reuse and recovered from electronics products and cards by sorting from many other metals or from sands. In mixtures of small gold spheres and sands have been sorted by an efficient method called eddy current separation able to separate the gold from a mixture of non ferrous particles. It's a mining sort and recycling industry. This study is based on the ejected force created by the eddy currents induced and the rotation of drum. These eddy currents create a opposing magnetic field to create magneto-dynamic repulsive force between permanent magnet of separator and gold particles, these last will be ejected in collector by gravity force.
