Dry Washer Air Sluice

The riffles in the dry washer's sluice box are pointed up towards the top of the box, instead of towards the bottom of the box. This allows gold to be trapped under the riffle.

Another thing about setting up a dry-washing production program is that you always set up a dry-washer downwind of where you are working! Once gold falls into the dead air space within the riffles, it will usually stay there. The air-flows are generally not strong enough to push gold out of there. There is a limit to this, however
