Suggestion: Get a larger funnel and cut your opening larger than the diameter of the tube which was originally part of the funnel. The column of water would be lower and the speed of the water washing through it could be far slower. The lighter particles of sand and other debris will still rinse out, but the finer flour gold will have a better chance of being left behind. Also, have a 5 gallon bucket below your bowl to trap your tailings for future run throughs. More gold can be retrieved.
1. Cone not high enough 2. Water inlet twice size it should be. 3. Sides of bowl straight - should be 15-20 degrees from vertocal ... 4. to test mix gold with dirt, not glue the pieces to the bottom first ... The point is to MAKE the gold settle and not to have it there to start with, other than that nice job!
1. 2.The bowl is bigger than you think, the cone in the middle is probably 60 mm in height. But i run it way to fast, with too much water. 3. The sides are not straight. Take a look at my version 2 of this bowl at my other video. But this first version worked much better.
My experience is that the thing works best if the angle on the outside of the bowl mirrors that of the cone, and the depth of water is greater than 100mm else you lose fine (micron) gold. You also have to be careful with the angle you inject the water at. It needs to be slightly downward and almost parralel with the bowl edges. I also took an old Dyson vacuum cleaner (cyclonic) apart and thos things work well you just cant process fast!
i have worked for a mining project trying to recover micro gold (5 -25 microns) from a polymetallic sulphide deposit. the best method equipment to use would be a high speed centrifuge running anywhere between 125 to 150 Gs. with a reasonable counterpressure recovery rates can go as high as 98%.
Interesting video, thanks but I'm left thinking, what would happen doing that same demonstration with real black sand. The heavy kind, that comes with gold con's from the real world of hard work. I'm not suggesting you do it but what if? To see if it works just as good. I guess I'll have to try some day. In this test you had to almost overflow the bowl to get the turbulence required to moved that "light" sand out. That leaves me wondering if using a denser sand, closer to the density of the black sand found in fine con's, whether the black sand would even separate in that bowl? Based on the fluid dynamics involved I find this an interesting video indeed. Thank you, Cheers
I have done a lot of testing, this version is 4 years old. Check out my last one, with fine gravel and black sand mixed with gold. Homemade Blue Bowl - Gold Recovery V3 If the sand material is very small, it moves out before the black sand. If you get some lager stuff in the blowl, lake i did in this movie, it will not get out.
Explanation? What was put in. How does the machine work? How do you properly operate it? What was the final outcome? Was that gold in the bowl? How much? Questions! Questions! Questions!
So many questions not addressed. Diameter of bowl, diameter of inflow, diameter of drain, + why that height specifically ? Why not make drain hole and water inflow the same diameter to equalize water level ?
Water level is adjusted according to the size of the particles. Your concentrates must be sized first, and a different water level is used for each size range.
Two things wrong; first, the bowl is not level, this is obvious because the water almost over flowed on the far end and second you are running it way way too fast, no doubt you washed away most of the gold. Other than that It’s a good setup.
I don't think the cone is not high enough..I think the outlet aperture in the cone is too small and so the water cannot leave as freely as it would if the outlet were bigger.The depth of water above the outlet hole is causing an updraft and I reckon you would lose almost all of your truly fine gold.
while its not"homemade"..these "blue bowls"save a lot of panning time...stick ur finger in the water and stir up the concentrates,cleans up a lot faster,with less water...and don't worry...ur not gonna sling ur gold out.....
Thank God...finally found a video without annoying, overpowering background music!

omg I have been wondering what the heck a blue bowl is and why people are raving about it. A thousand thankyous for posting this!
It is a funnel. I tested with a much steeper funnel at first, but the result was the same.
I bought it at "Överskottsbolaget" here in Sweden.
It is a bowl used for washing, marked Made in Italy Tusfra.

you need some soap or jet dry to break the surface tension of the concentrates
omg thats incredible! can you show it working in the field, with a car battery?

that worked really good what did you use .to make vortex
great money saver, may i ask what you used for middle peace? thanks!
You need a little dawn soap so you don't lose the fine floating gold

Thanks for the linkElfix000
How was the funnel afixed to the blue pan?
This one works better than our store bought one !! make a video showing how you made it so we can make one or maybe you would sell us one.
Get a bundt cake pan from a second hand store and cut the center down to suit.
Sir, is this machine works for e-waste gold recovery process?
where did you find the bowl at

Um it's homemade and it's one of a kind

Cool where do u get it?
Perfekt!

Where did you find the bowl ???
Genius!
Where did you find the bowl ?
How many watt the water pump needs?
what are u putting in 2 the bowl
Very nice but wish you would have talked about how you made this one.
This person lives south of the equator? Normal blue bowl go's clock wise. :)
That was awesome!
It makes a pretty awesome tornado inside
Nice clear video, but no one is telling what is happening! Would like to know what and how it is doing it!
What diameter funnel, and how tall?
qual angulo e altura do funil ? qual altura do furo da entrada de água?
How tall is your funnel ?
I don't think the cone is not high enough..I think the outlet aperture in the cone is too small and so the water cannot leave as freely as it would if the outlet were bigger.The depth of water above the outlet hole is causing an updraft and I reckon you would lose almost all of your truly fine gold.
In version 2 i made a larger opening, but lower. Did not work that well. Homemade Blue Bowl - Gold Recovery V2

Will it help to add mercury in the bowl?

,
only applicable to big chunks....not suitable for water gold
From what I've seen of other blue bowl demos you seem to be running it way too fast. You probably washed gold down the drain
To much water pressure

@Bushidobull
thats just sand..
oh its tryin to get the gold my mistake
12Hqa what else would it do?
Talk much?
