The patented RP-4 is designed for separation of heavy mineral and gemstone concentrate.; The RP-4 table can process up to 600 lbs. per hour of black sand magnetite or pulverised rock with little to no losses.

If your assay shows values for gold at almost 13 Troy oz./ton, there would be, assuming a specific gravity for magnetite (black sand) of 5.0, roughly 64 Troy oz./ cu. yard of black sand. IF there is a layer of clay below your placer, it will catch all of the migrating gold in a layer approximately a few millimetres thick on the clay's surface.

The clean black sand and fine gold is added to the black sand fines obtained by dredging, sniping, or sluicing for final processing at the end of the prospecting season. At the end of the prospecting year (which for me is late October or early November), I have accumulated something between 20 and 40 pounds of black sand concentrate.

It takes extremely good panning techniques to capture it in a pan, and a high energy sluice will generally wash the micron gold out with the tailings, maybe even easier than washing out the fine black sand. If you suspect you have micron gold, the first step is to look for it with a good 20X or 30X magnifier, looking for discrete, small ...
