Processing serious flour size gold, working with super fine gold Options

[jackragusa]

I read a lot about folks working with a Blue Bowl on very fine gold, but I find it's much slower than just panning . Besides, the seriously fine golds also works it's way out of the blue bowl even under the slowest workable speeds. I have a large bucket of con.s I would love to go thru and I am sure the gold is there but the labor of just panning is just not worth the time. Other than a wave table or a shaker table which is obviously way too expensive to balance out, what choices do I have. Even if there was say an ounce to an ounce and a half of flour gold in the bucket, I would still be making only half of min. wage panning it and I do ok panning. But with panning this size gold, you have to go thru everything three times to insure you didnt miss anything. So please HELP....

Hi Mitch and welcome to CP.
Good post...
The LeTrap boiler box creation is interesting. Are you saying that you use this as a final cleanup device.... or used as a field sluice?
If it's for field use..... a potential drawback for me would be production. I typically don't like to class down any further than 1/2". It's a time killer to hand-class down to 1/4" when you're trying move a lot of material. I'm guessing the unit runs off a 12V bilge pump. I don't doubt that it does a great job of recovering micron and fines. It just appears to be one of those things that takes a long time to process volumes of rough.
That being said, I'm kinda interested in the concept. I occasionally hit areas around the state that have primarily micron, maybe it would be useful for that. Most of my dig time however is at my claim. Not a lot of micron Gold there and high production is way more important, short season.
