I'm curious about the use of a rollup mat for beach sluicing that used the flow action of the water.
My idea is this:
1) A rectangular mat 2m x 0.5m. Ribbed, or rubber-backed miners moss.
2) Used on a shallow sloped beach at a point where the wash from waves covers the sand periodically (every 10 seconds or so on our local beaches, near Newcastle, NSW), in a shallow curved trench that concentrates the water, anchored at each corner.
3) Waterflow would be back and forth, but gravity and speed would, on average, work downwards.
4) Feed of sand would be to the middle of the sluice.
Has anyone tried something like this before?
Would it be effective at trapping small amounts of fine gold?
