Bucket Fluid bed idea...

[G-bone]

OK, just thinking out loud here and curious as to what you wonderful people think.
This whole fluid bed sluice design thing is great. but I was thinking about how to get er done without good "natural" waterflow.
I guess this would even fall under a "high banker" fluid bed of sorts?

It is very rough in concept and if pursued would totally need fine tuning and some changes here and there for sure.
But the concept itself does shine thru here... I think.

G-bone, I like it ! The concept is solid.
"...totally need fine tuning and some changes here and there..."

Curious how to acquire the circular tube?
How to clean out the unit?
Is this something you found on the old interweb or did you design this yourself?

There are a few people on here who have toyed with the idea, including myself. What's that saying, go big or go home? Take a look at this.

Thanks UnderB,

To answer your questions...
1 - Fluid jet tube could be PVC tubing heated up and bent maybe? Drill holes etc.
Could even be flexible garden hose for that matter.
2 - clean out would be turning over and dumping into pan as I see it. maybe the
3 - There is the "Nugget Bucket" on the market which utilizes the fluid bed idea as well.
But it is all gravity fed and requires you to Classify by hand (two different size screens which you clean out by hand as well)
Also, Water feed is manual as well. You need to pour water into the classifying screens manually.

That said, this variation is my concept, but with input from others ideas.
There is another Bucket design out there from another Tnet member that I derived the Grizzly layout from.
I don't recall it being a fluid bed type internally though.
I wish I remembered his name to give him props for that.
I am curious to see if he has refined his design too.
Maybe he'll see this and ad his two cents and update us on his latest version.

On mine though....
The actual fluid bed area may be too big as I have it.
That's one of the things that would need to be fine tuned as well.
Fluid tube size, hole size etc, all to be determined.

Very cool QNCrazy. Great job.
Guess I should have searched a little harder on Tnet for this stuff.
Definitely going big there, that's for sure!!

Cheers

On the last box type fluid bed I built, I ran the jets so they point to the head of the box and also angle downward to sweep the bottom. I figure if the jets push any gold, at least it will be toward the the head and not the tail where it might leave. My box also has the tubes about an eighth of an inch off the bottom. You will have dead spots under the tubes, but less dead zone at the bottom of the box and under the active areas.

You can see the dead zone created under the active areas with horizontal jets. This lessens the depth of the bed. The bed is 2 1/2 inches deep, and I'm loosing a good 3/4" of depth.


Here is what downward angled jets do. You can see the black sand line moved to the very bottom of the box. Now the gold will move to the very bottom of the box.

Don't think it's a new idea, but anytime you come up with something independently there's a good chance you'll introduce new innovation.

I'm very sure there was a recent thread. Hunting for some videos...

Not quite the same but playing with a fluid bed design


55 gal version


In fact, Matt has 10 videos, just click his name to get to the others.

And, well, because it turned up during the search...... sorry... truly....

 

[G-bone]

That was it!!! Astrobouncer made one just like it.
I knew it was here on Tnet that I saw basically what I threw out there.
So yeah, nothing new.
I'm glad it brought those earlier ideas back to light though.
It's good to see them and learn.

Astrobouncer, if your out there, any update on the version you made? Refinements?

Thanks all.

Me too...as long as you add a way to wash the rocks before they hit the grizzly. Gold likes to stick to big rocks...gotta wash 'em!

 

[PurpleGold]

Awesome idea! KIC has the exact idea I was thinking. There needs to be a way to slow the material down and wash the rocks as they get classified off the grizzlies. Around here there can be a thin sticky layer of grey clay on the cobblestones. I usually hand scrub these in my bucket.

 

[G-bone]

PurpleGold,
You and Kevin are absolutely correct.
That is what AstroBouncer was thinking too.
I am very curious if he has revised or updated his version since he made the video.

Cheers all

You said natural water flow but you must be using a pump? How many gpm is your pump?

A simple basic fluid bed that works great can be made from a round tub and a mesh trashcan.

https://www.google.com/search?q=pla...1Y7aZd-Id7wKOHw=#tbm=isch&q=round+plastic+tub

https://www.google.com/search?q=bas...h4KHXjoBUgQ_AUICCgC#tbm=isch&q=mesh+trash+can

A small inexpensive one inch 30gpm pump with a one inch hose in a 10-15 gallon tub so that it creates a vortex. Fill the mesh can with material dip it in and out of the tub to classify. The tub will overflow the lightest materials and keep the gold dead center on the bottom of the tub.

Turn upside down and drill holes bigger?

Now do you subscribe the gravity theory of causation or smashed on?

Sorry but I don't understand the question at all. It may be because you're from Pluto (per your profile!) but can you try again?

My pleasure The question was about the reason for the gold being stuck to big rocks

 

[KevinInColorado]

Oh right. I think it is gold flakes settling into a rock and getting cemented there. The rock may then move and change orientation so what was the top of the rock is no longer but the gold is still adhered to it. But that's just my theory...

 

[ebuyc]

Yeah I was going to mention Astrobouncer's version also...
