- How to use a Blue Bowl to clean up gold concentrates. More fine gold recovery tips can be found at the only informational source for Southeastern Gold Prospectors: goldprospectingtips.blogspot.com
This is my method of cleaning up gold concentrates. Following this method net me nearly 100% gold recovery. Follow the instructions on the Fine Gold Recovery page on processing the black sands. In many cases, the gold can be "encased" in the black sand and not visible. Following my method guarantees you will recover the hidden gold. - Наука та технологія
Must have device for every gold refiner
Thanks for video
Concentrate is the material you gather out of your sluice box after running material through it. It consists of all the "heavies" your sluice caught.
What is ''concentrate'' ? Do you pick that with a shover near a creek or a river or it is pre-filtered stuff
Wow you found all of that gold and with no black sand at all... Lucky guy...
Are you talking about the older version of the blue bowl?
Thank you for the great video. It is very helpful
I saw a guy use one like this before and he fed the concentrate in a little at a time. He lost only a few flakes.
does it also works with a green bowl ?
If you lay all the material on the floor of the unit to start with,will you not have to use excessive water flow to get it mobile again?If you slowly add material to the input flow.the heave elements have a good two to three rotations of the bowl to settle out.lower water volume means finer particles will settle out.also with movement you get centrifugal force (kind of the hole reason for using a vortex in the first place)which should help keep value away from the top of the out put.
+TheJustinhcase Sorry for delayed response, been locked out of account but back in business now. What you are saying makes complete since. My reasoning behind my method is that it is classified so small that I fear when I drop the material in, the gold "dust" will get funneled out of bowl. I don't see anything wrong with your method. Best of luck prospecting to you! Thanks for watching
@Tim Kasey
Thank you for your informative comment(s). First off, my goal with the video was not to promote a blue bowl but to provide tips/advice/technique for using it. I have no affiliation with "Blue Bowl" besides personally owning one.
Second off, I'm confused as to what would be "not right or fishy" with the video. To sum up your lengthy explanation comparing gold recovery to "medium" mesh, gold is heavier than the "medium".
Thank you for your input.
very good video
I use a 70, 100, and 120 screen. Nothing bigger than 70 is bluebowled. I don't even try to get perfectly clean gold with the 3 runs. I just try to get most of the junk out. The crucible, flux and torch will finalize the process. Blue bowls are to get ready to smelt, not to totally clean up. It is amazing how much gold is less than 120 mesh!
HM Dickson you are right!
I just ran some medium, and the following two comments (down there) are what I discovered on my own. I don't see any videos mentioning these details.
What are you classifying you concentrates down to?
+Appalachian Prospectors 70 mesh in this particular video. Sorry for delayed response, I've been locked out of my account. Thanks for watching!
Красиво и быстро.
Ive watched fifty videos already about the blue bowl but nit person says where the hell to get one. Can you please tell me where you can buy one of these awesome bowls
+Gino Lopresti ironically, 50 is your IQ
eBay
You go onto Google. In the search bar you type "blue bowl mining" + the city you are in, and guess what? A whole bunch of retailers pop up including Amazon and eBay. Pretty amazing eh😁
Dont you have the damn internet. Jeez man look it the hell up😢
@@Triumph4212:29 AM And I forget my comment... Oh, that's what it was, have you tried screening to less than 70 mesh? I do 50, but I can see a lot going over the edge with a flashlight. Reason I ask is I found out hard rock gold averages between 200-300 mesh. I've only gone 50 mesh and fine screen is hard to find, but eBay has screen down to 500 mesh, Blue Bowls too, and my plans were to screen at 50, 100, 200 and 300 for shits and grins. Anything smaller than 300 will probably blow right on out unless you have just a trickle of water flow going over the center lip. I just got into classifie'ing as screens I couldn't find before and from what I've learned is you want the particles of mineral and gold close the the same size like how rocks bounce down a sluice and potentially dislodge the smaller stuff on the way out. Not for small batches as the bowl is painfully slow as it is. Just a thought, and when I make my screens and process what I have I'll report back with results. I think 400 to 500 mesh is the extreme limits for gravity separation and it's a totally different animal getting that fine flotation being one of the, I also use dawn dish soap as a surficent to break the water tension and prevent gold from floating.
Happy digging
American Blue bowls spin the water clockwise.
Perhaps Australian ones should spin it Anticlockwise.
This is the way our water swirls down the sink,- Unlike on the other side of the Equator.
Unless we are looking for the extra turbulence.
@SouthEasternGold - or - anyone that can answer this ! -- Will the blue bowl remove beach type sand or Only black sand? Where I live and prospect, it is always sand left at the end of my pans. I am aware I am looking for flour gold, which is why I want to invest in the Blue Bowl, but no one has been able to give me an answer if it will remove beach type sand? I fear I am losing a lot of fine flour gold in the sand. - Thank you in advance for any help you can provide!
for any one to render an opinion with out having tested your material would just be a guess. If you can pan it,the blue bowl should speed up the process.But it is not magic . material has to be classified to very tight size.the tighter the size the more effective it will be.
Buenas que estupenda idea donde venden el tazón
You're going to strain your material you use classifiers you should have three of them you can pick them up front of twenty bucks a piece and that blue ball should work flawlessly once you understand how it works
Yes it will it is made to remove all light and black sand
couldnt he just run the concentrate through the bowl again?
50 mesh works best for me
I will keep that in mind for upcoming videos, didn't make you have to pee did I? lol thanks for your comment
You don't have to turn into a gabaholic, but a little voicing would help a load, maybe explain what you're doing and why for the newbies amongst us. Other than that, nice, I gave a thumbs up.
Very nice, 🎊🎊🇵🇷🇵🇷💯
W O W ! ! !
It looks like you were running it pretty hard.
why you use soap
Use jet dry or something similar, not just soap, it breaks the surface tension between the water and the material so the gold will sink easier and the fine gold is less likely to float on the water and go over the cone.

Wheres the how to?
A voice would have made this better besides the sound of water
If you classify down with a 75 per inch screen, and the gold is smaller than 100 mesh, the gold dust will go right down the drain. If you don't give the exact sizing of the classification these videos become misleading. If I were to mix gold of a greater than 75 (per inch) mesh with a medium of less than 100, I would be misleading the public. The real world is different from setting up for maximum effect to promote a blue bowl.
Tim Kasey true!
Way to much at one time
You're running it to fast, not to mention with WAY to much material.
The "cons" should never run that high up the cone. You're gonna LOOSE ALL your fine gold running it like that.
Something not right with these videos. The gold is slightly larger than the medium. When you classify down, the gold (if smaller) goes right over the side of the drain. You can't separate out gold from the medium if the gold is smaller than the medium.
