Lower speed or velocity is required to recover fine gold in the lower or separate sluices. When the speed is high enough to carry off the larger non-value cobbles through a single sluice box, a loss of fine gold can occur if the material and flow is not separated.

I think using miners moss underneath your riffles is a real important item for capturing that fine gold. That is why miners moss is used in the sluices of nearly all commercial suction gold dredges.

Under the riffles, ribbed carpet or miner's moss is used to catch the fine gold. The old timers used burlap for this, and so can you. It still works just fine. Plastic sluices generally don't have carpet. They use either molded riffles or molded traps in the bed of the box to catch the gold.
