Do you sell just the sticker of lines for mess count ? I've been experimenting with the blue bowl I've high grade platinum Ive removed from crushed rock, blue B. Did help get some of the gold from it but found myself replanning the platinum. Have you tried blues with any other minerals other than gold ?
Hi, I don't know if Steve is still running this site or Dave who now has the Copyright from Steve but this is one of the best inventions I have ever seen and used. If Steve is still running the site all I need to know is the name and size of the blue buckets you use on the demonstration videos please? I purchased my Gold Lab from Dave and am more than happy with It's operation, the only problem I'm having is where I am presently using the round black buckets I am having a lot of very fine sand coming out of the bucket on to the bottom of the main water run and being pulled back through the pump with the clean water in to the bowl. If anyone can help by letting me know the names and size or where I can buy 2 of the buckets that Steve used on the Video demonstrations I will be more than grateful, my email address is ian.mcdonald-wallington@sky.com. I am asking for this information because Dave told me a few Years back that production of The Gold Lab has stopped, with my Lab being a few Years old now and me living in the UK at the moment I will only be able to buy anything needed for my Lab. Any help from anyone will be appreciated.
its just a blue bowl and a micro sluice both items cost below $50 each lol laughing my butt off while I was watching this I wonder how many people actually purchased it haha
Fasten a nut on the inside of the tube so the tube threads do not strip out. or put a tit on the tube put a hole in the flat stock. Just above the tit have a rectangular spring steal piece fasten to tube hanging over the tit. Now just lift up the sheet metal and slide the flat stock over the tit and let the sheet metal spring back to hole it. You could better electric connectors. for the lamp post, insert a piece of smaller tube in the upright you have it fasten to so all you need to do is put the lamp pole over the smaller tube and put a lock pin in it. just like you hopper pins. Do the same with the hopper post. Nice idea. But a table with none stop feed and none stop collection would be the cat's meow.
Onde seria o local ideal para a retirada desse material, moro no brasil e tem muitos garimpos abandonados, faz um video extraindo o material do garimpo!!!
Maybe you didn't need the answer anymore...Anyway, you can distinguish between them using acid. Fake gold will react and real gold does not. Another way is checking the density, gold is really heavy, much heavier than fake gold.
> "[...] you can distinguish between them using acid." The problem with acid is that you slightly damage the surface. You wouldn't like to do it with your gold coin. Besides, it only test the surface not the interior. > "Another way is checking the density [...]" The problem is that there are other elements with a density very close to gold (ex: tungsten). A gold bar filled with tungsten inside would fool this test. Any idea how to avoid such issues?
> "You either need to use an ultrasound device [...]" Gold coins are too thin to use ultrasonic devices. > "[...] or measure the specific gravity." Tungsten filled gold bars can fooled this test.
Roger Nevez Yes it is possible to fool a specific gravity test with a tungsten core. No coins are not too thin for a high quality ultrasonic thickness gauge that is designed to measure ranges of thickness found in common coins. here is example www.dakotaultrasonics.com/product/precision/px-7/
Try placing a strip magnet underside of blue bowl at angle but stay 1 or 2 inches back from bottom of cone meets bowl to allow material to pass this will collect your black sands in the bowl an allow the blue to wash it some .
That's a nice set up & some great ideas for the blue bowl. The only thing that I do different is that I have the valve for the bowl mounted away from the jet so that it always has a full stream entering the vortex. But you have definitely turned this into a fine product 8°)
