Sluice Building For Fine Gold Recovery – Part 3 – BC Gold ...

Sloped Flat Bar Riffles. In general, flat bar riffles at virtually any slope failed to generate efficient concentration vortexes and seemed to operate basically as dams to interrupt and slow the water flow just enough so that the normal gravity settling characteristics of the various particles came into play. As a result capture of heavy materials was primarily based upon gravity so retention of fine gold is very poor.

» Double-screen Classification System in Dredging

Classification is the Key to Fine Gold Recovery. It is well-established that if you want to effectively recover finer particles of gold, you must first separate them from the larger-sized materials which are being washed through your recovery system by a higher-velocity flow of water. The small-sized material can then be directed to a milder-flow of water over a shorter set of riffles.
