I'm kinda fond of this configuration for the Gold Well. Three 12" Gold Wells side x side.

do you know how many yards per hour was being run thru this sluce ? looks like it might be on a ocean dredge ? do you have anyone using your sluice behind a shaker screen or trommel ? and how does it handle the increased volume ?

I'm thinking about using a 1/4 inch stainless organizer thingy as a classifier on my sluice. I am wondering if I set it in the slick plate as the photos show, if it will allow enough water to clear the smaller material without impeding the sluice box. I've got good flow where I will be doing this.

Has anyone else tried this or similair? Good results, bad?
Thanks

To add... I am already dry classifying to roughly 1"

Here is my setup. Its a work in progress as I am building everything at once. The sluice is 12 inches wide, 60 inches long, 4 inches tall and made of .080 aluminum. Has Gold Hog Mats from top to bottom. Will be fed with a 8000 GPH pump running the sluice at about 8 degree angle. This is a recirculating system using 3 tanks with the pump in the last tank. A very fine screen will be installed around the 15 gallon barrel covering the 12 two inch holes. Will be using a siphon system between tanks to keep the water balance while all water will be pulled from the center water level in each tank. You can click on the photo a few times to view it in full size.

Increased material volume is not much of a problem. It handled the Nome black sands pretty well. Not sure on the volume they ran there, but we have run 5 yards per hour without the sluice loading up and losing gold. I have never run it to the max yet, but it's looking like (depending on material of course), the Gold Well 12" model can handle somewhere around 8 or 9 yards per hour under optimum conditions. I do know that it kept up with the material processing on the AU Grabber, as it had to process all the material daily that the main sluices processed. 3 feet wide, 1 foot deep. And as I understand it, in the end, final configuration, 3 Gold Well's were not used or needed for that task. (Hey Hank if you read this and would, why don't you fill in some of these details.)

Water like shown in the picture becomes a problem if you don't slow the velocity down before going across the sluice. The Gold Well really doesn't need very much water depth as it won't 'scour' like a regular sluice can. And a lot more volume is fine, but you can't blast it with a fire hose. Water velocity is the factor that needs to be kept in mind with a Gold Well. In that photo it was being run on the AU Grabber (huge ocean dredge, one of the biggest) in Nome, AK this summer with excellent results, however NOT in the configuration shown as the pump they had was humongous and was designed for their normal style sluice.

They ended up as I understand it, dumping all the output from the main sluice into a bin before going over the side, then sucked that out of the bin and pumped it through our sluice with appropriate water flow. Shown in the picture is my brother who was there (whom I communicate very little with and thus know too little also), and that was from a 4 hour run, the gold captured as I understand it that would have been blown back over the side from the main sluice if the Gold Well had not been inline in the process.

Yes, there are people using them behind a large New Age trommel as well as home made ones with no issues. It really doesn't matter the method of input. I am almost done with the dredge crash box for these units, as well as a nifty unique new stand/cart for dragging sluices around in the boonies rather than carrying them on your back (for those that have to pack in), so I am trying to accommodate any desired method of input.

People who have seen or use my sluice are amazed at the throughput on it, and a lot of them think they need a big one, yet, when they find out how much a Gold Well can process, they soon realize they don't need such a huge one after all. But, for those that really DO need something big, we have a countersunk screws option (flat head screws used on the sides after we countersink them), that allows them to be ganged side by side, and for those wanting a longer one, they can be daisy-chained, one sluice dumping into the next, either a simple frame made to set them in, or simply using some kind of fast release clamps to hold them in the desired configuration while in use.

There is a video that one of my customers did, that shows them running a few buckets (the last of 20), in Happy Camp this summer. They only classified to 1" (tbh I never classify at all myself when I go out, I'm too lazy and put those 20 buckets through a 12" in 14 minutes. But if you watch the video carefully, you will see that he's pouring out of the bucket down the center of the sluice and so only 60% of the sluice is really being utilized, as well, I can tell by watching it that the sluice could handle probably another 15% more material as he is underfeeding it. Then too is the fact that he walks away to get more buckets, during which time there is nothing going through the sluice. So you do the math, he's way under max, but that puts it easily up in the 120 - 180 buckets per hour category.

Well I hope that answered your question satisfactorily Bill. If not let me know.

Nice sluices in here!

lets see some more plz

 

[socalocmatt]

Added a little upgrade to the a52a. Cut and bent some expanded metal to fit over flare.



Gonna test that out to hopefully cut out the classifying.

Also added a rubber flap to see if that'll help dunk dry material under the water line.

36" Fluid Bed Sluice
My Fluid Bed Sluice is a product resulting from hundreds of posts offered here and there. After a Dry-Washer my next contribution to prospecting was Mike's Trommel and now it's my fluid bed which is designed after the Bazooka. All of my tools have been of the DIY nature. Howard Schmidt's patent caught my attention and I had to have one in my ensemble. See my project by clicking here.

 

[KevinInColorado]

That's really gorgeous, nice work! I bet it works great too right? How did you decide on the hole patterns in the tubes?

My DIY super fluid bed high banker 3" dredge sluice designed for high production fine glacial gold recovery..........................





Also my DIY fluid bed combination highbanker/stream sluice with fold out wing dam......






Almost left out my DIY concentrator sluice................


Plus many more but these are my favorites.



Go for the gold,
GG~

Kevin,
I did a lot of research and I think I got the idea from someone on this forum who said they just got their sluice in the mail and described a hole pattern like this. The middle tube staggered with 1/8" holes along the center and the outside tubes had holes on half inch centers about the 45 degree angle downwards. Almost every part of this sluice has been taken from different places. I think I have as much fun with DIY projects like the sluice and dry-washer as I do finding gold itself ............. but there is nothing like topping off your first ounce!



Cheers,
Mike

Very interesting and a combination of form and function that's just inspiring

Kevin,

Just finished building a stand for the fluid bed sluice. It's pretty cool and thought noteworthy to be posted here. Again, got ideas from around the net and changed them to fit my needs. I posted the build to my server. Mike's Gallery :: Sluice Stand

Very sweet. Another thoughtful, elegant design. Looking forward to seeing it get wet!

 

[Prospector70]

I like the fold out wing dam!

 

[Goodyguy]

I like the fold out wing dam!

I thought it would do a better job in open water than it did. However it did work great in certain situations though.
Anyway I took it off due to seldom using it.

24" Fluid Bed Sluice

........ and so completes my winter projects with a small 24" fluid bed sluice.

This sluice has a larger fluid bed than the flume plate above and also incorporates an experimental "hydrofoil" design to create a low pressure drop for the heavies into the front of the bed .......... we shall see ............ There are two 1" tubes with 1/8" holes drilled at 45 degrees on alternating sides, spaced at 3/8" intervals. See the plans here.

I really like that.
I can't seem to get a lot of production atta this....
