Jul 17, 2021The shake table is a kind of gravity separator in the inclined medium flow. It uses the combined action of the specific gravity difference of sorted minerals, alternating movement of bed surface, and transverse oblique water flow and riffle (or notch groove) to allow loose layering of ores on the bed surface and fan-shaped zoning.

How I built a recirculating sluice box for gold prospecting

But I decided it was high time I learned how to weld anyway. So I bought some 1/2 x 1/2 angle stock and some 1/2 x 1/8 flat stock. My intent was to use the flat stock as rails on either side of the sluice and weld the angle stock between them to make riffles. The entire steel riffle assembly could then be lifted out of the sluice during cleanups.
