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.

Good info guys, thanks.

I agree with Astrobleme to..... Without the proper know how and equipment........

I don't encourage anyone to attempt fine gold recovery with mercury as the dangers outweigh the gains, in my opinion.

I'd say if you can save them up for more quantity, then it's probably worth trying new processes to catch the finer gold. Using magnetics to gently seperate the cons will definately help both wet and dry. When drying, use stainless steel shallow pans and spread them out. If there is any free natural merc you will see it gathering in a low spot or corner too.
The surface tension on the water when running these cons after the mag seperation should be a concern as well since the finer gold can float off so easily. The two best ways to combat high water tension is to let the water warm in the sun (warmer = looser molecules) and then some type of soap or jet dry as all water will have oils of some type in it.....even oil from your fingers will contaminate the system in time depending on water volume used.

I think the show mentioned above used some of these same techniques and they do work well. Hopefully they help.
