On the three stage sluice, most of the gold gets caught in the upper part. As the gravel passes down the box, it goes over a screen, which in my sluice has 3/16 inch holes. The fine gravel and smallest gold goes down through the screen into the lower or underneath section of the sluice. There the slower water allows the fine gold to settle out.
