  • Particle classifier apparatus
    Patent number: 8763812
    Abstract: A particle classifier apparatus used to mine for gold and other precious particles. The present invention is meant to replace the sluice box or any inefficient means for gold mining. The present invention is used with and without a stream of flowing water. The present invention comprises a PVC channel, a main trough and a plurality of small troughs. The PVC channel comprises a slit with a narrow end and a wide end. The present invention is designed for the stream of flowing water to flow from the narrow end to the wide end. The water flow pushes the particles through the slit and into the plurality of troughs located beneath the slit. The smallest particles fall into the narrow end whereas the big particles fall into the wide end. The plurality of small troughs are removed from the main trough so the captured particles may be panned for gold.
