Recovery of fine floating gold - Finishing

2008-1-25  The gold floats because of the surface tension of the water. In a small recirculating operation you can use a Jet Dry or dish soap to break the surface tension and the gold will not float anymore. With a dredge as long as you don't bring the gold to the surface it shouldn't float. Maybe a deflector to keep it down in the sluice might help. Good ...
