Wilfley Tables—Repair, Rebuild & Set Up
September 2014 by Roger NeuschelerI researched the Internet and found a number of table makers, but technology has changed in the last 25 years. No one could sell me a kit for a new deck with wooden riffles...
If Epd is larger, then the compressor will be spinning faster than the manufacturer’s maximum specified RPM and might destroy itself. If this happens, then the compressor again might not produce enough air to support a diver. Neither is a desired outcome.
I love to dry wash old nugget patches found by detector operators, and I have found my fair share of gold dry washing those areas. I have also found a few nuggets using a detector on the bedrock exposed by dry washing the patches.
“The evidence is clear—mineral deposits alone are not enough to attract precious commodity investment dollars...”
A Wilfley table works best when all of the mineral being run across it (the pulp) is about the same size. For this reason, I took a good look at each of the samples.
All these decisions and more depend on the richness of a claim—something that is determined by sampling. But sampling isn’t cheap, and even collecting the samples can be more difficult than it appears on the surface.
…as an academic argument, when mated to the appropriate engine, is the pump really moving water at the rate of 400 GPM?
The problem is that extracting gold from hard rock is often a lot more difficult than processing placer gravels. Still, there is some very high-grade ore out there in many old mining areas.
