What do you do with your black sand? Options

[rich on western ...]

How much micron gold is usually in black sand? How much sand do you need to be worth looking into separating this stuff? Is there anyone that buys it? I was going to run mine through screens and put it in the blue bowl next winter just to see if I missed anything. Do both mag and non mag sand contain gold? I hear that it makes great soil mix for rose gardens too.

I have a stereo microscope and a couple of years ago I used it to study a concentrated black sands sample that I had collected from the Arkansas River near Salida. There was quite a bit of fine gold mixed into that sand that wasn't visible to the naked eye!

In the "old days", placer miners used mercury to collect the fine gold without too much effort. Of course today, mercury is a very highly controlled substance that isn't readily available. The particles I observed were clean free gold and would have readily been picked up by mercury. I don't encourage anyone to attempt fine gold recovery with mercury as the dangers outweigh the gains, in my opinion.There was a Gold Fever show a few years ago that featured a guy in California recovering very fine gold. He did quite well but had a lot of experience and some specialized equipment. If you can find someone that knows that process, that might be worth pursuing.
