Which Type of Gold Dredge Jet is Most Efficient?

[@tylers1219]

I have never gold mined before, but I happened to stumble across gold dredging just about 2 weeks ago. I immediately thought of a different use for the technology as a local service i can provide to people. I’m a big data guy, and it was pretty hard to find information to learn more about jetlogs, the jetting, nozzles, all of it. I truly love what you are doing for this niche community. I did a looooot of video sifting, and was eagerly awaiting your video to learn some more, since you provided the best information by far. Data backed and simple. This week i completed my first successful 4” jetlog, and in my test runs, so far i have been able to attach a 60 foot 4” suction hose with insanely strong suction, and pumping about 5ft head after the jetlog. Which serves the purposes of what i need. Its been a cool learning experience, and im excited to dial everything in, and hopefully try and step up to a 6” dredge and even longer hose setup next 👀 i appreciate You, man 🤙

[@UtmostOutdoors]

That's very cool! I'd love to learn more about what you're doing... I guess for the general plumbing setup of a suction dredge this sort of video really is a good overview! I appreciate the support!

[@matthewcolbey9616]

Love your work and videos...keep going on the 2" inch dredge battery pack efficiency model i would definitely be keen to get one...hooked up to your your double decker high banker...what a machine

[@UtmostOutdoors]

I'm not sure how feasible an electric dredge would be to run into a highbanker due to the lift required... I'll get the plumbing sorted out for something that floats first. Either subsurface or just above the waters surface... I'm sure this can be done!

[@tylernelson276]

I can personally say that venturis in series greatly increases suction power. We used a 4in hydro force nozzle to lift material at a high velocity 6 feet vertical, then 20ft feet horizontally to a second venturi, then 10 more ft to the dredge. None of this was done underwater, so no buoyancy effect to help lift material. Spacing of the venturis did seem to matter so it would be interesting to see you experiment with that. Another thing that seems to help increase suction is to add air to the nozzle. They seem to suck harder when air is introduced into the nozzle. I have seen air lift systems to clear out a well and it's amazing the effect you can get from air trying to rise in a pipe. Best of luck to you.

You are really progressing with all of your research on smaller versions of dredges. Love it! Floating mini Le'Traps.🥰 comes to mind. Although I probably will never use one here in Alberta, at minimum, a powerful portable jacuzzi to ease my aching joints at my age. I did link your video to some US prospecting forums and my Facebook drop riffle forum. Keep up the great work Kyle! 👍

[@UtmostOutdoors]

Thanks John. I like the idea of a mini drop riffle designed around dredge flows... thanks for sharing the video where it may be useful for people!

[@robinirwin4306]

Fantastic. Would love to hear more.

[@Jaybo79]

Great work friend. Thank you.

[@jasonaucolorado5111]

I would really like a ready-to-go kit that I could attach to my 2-inch power head sluice with a Dream Mat in it.

[@BruceMiller-n1k]

Hello from California. I’ve been using gas and electric dredges for year’s. Right now I’m using electric 3700 in your video with a Goldibox dredge and high banker. I believe you Larry that makes the Goldibox dredge have a lot in common. The two of you might be better off working together. I will be watching you both. Good luck

[@Than661]

Cool Video, I'm excited to see where this project goes.

[@GamingKeenBeaner]

Interesting video. I have been working on my own design and I have it currently using 6.435 liters per minute(1.7 gallons) to move 208.198 Liters(55 gallons) through the suction intake. Your videos have been helpful in this quest.

[@UtmostOutdoors]

Glad to hear you're having success!

[@GamingKeenBeaner]

@@UtmostOutdoors Yes your videos have been very helpful. I didn't understand before your series just how outdated venturi tech in the gold business really is. They're mostly using concepts from the early 1900s. The velocity is the most important single factor on the motive water stream; so the more pressure the better! I'll try and get a video up soon about this. I am going to be doing some tests on propelling my boat with this venturi since it moves so much water......

[@Jeepmeat1974]

I went down this road about 10 years ago but 3D printers weren’t really that accessible back then I love your ideas man ! And I’m interested in seeing how you go with making up a system and possibly interested in buying a set up if it’s affordable ! Mostly cause I’m in Australia lol 😂 we always pay more here man

[@MrTebrown]

I have been following this like the superbowl

[@facetious_1]

I really like these 3d printed jets/logs/reducers,awesome ideas for handy sniper dredge, for when a large 4" is not needed...working cracks etc. Once you lift the sluice above the water. I worry for the bilge pump capability. Ebay has 12v brushless cntrifugal with controller. For 60-100$, they can provide way more lift/pressure. Less volume overall in comparison to an open end bilge rating. But waaay better head...

[@mattharper7395]

Definitely would be interested in setting one of your dredge nozzle and upgraded bilge pump. Would like to try to assemble a small 6” wide floating Dredge that runs off batteries

[@SentinelFive]

Testing water suction nozzles with a dried up houseplant in the background is an interesting contrast 😀

[@swedishpsychopath8795]

Hmm...... maybe you aren't into engineering, Kyle? But why don't you read yourself up on what Bernoulli wrote 286 (!) years ago about hydrostatic pressure and use his formulas instead of the try and error approach you are performing? The solutions are there - just use his formulas, but here is the gist of it: Bernoulli's theorem: How the pressure and velocities in a fluid (water, air, etc) are connected The pressure in the liquid + the velocity pressure + hydrostatic pressure = constant as long as the energy level does not change. General principle: The Bernoulli effect is in principle a way of expressing the conservation of energy. The work exerted on a volume of liquid (water, air, etc.) due to pressure is equal to the change in kinetic energy of the volume of liquid. General characteristics. Where the flow is slow, we will find a relatively high pressure. Where the current is faster, there will be a lower pressure. The curvature of the streamlines reflects pressure gradients (pressure forces). Decreasing pressure in the direction of the center of curvature. In short: P+21​ρv2+ρgh=constant

[@facetious_1]

That's the same information, hydraulic miners used to level mountains 100 years ago. The old theory's & math did not change... it worked waaaay back when. The information still holds true today....😂

[@robertw8897]

I use SeaFlow pumps for my electric system as well.....so I am extremely interested in the improved impellers for the 4700 gph pump and the nozzle with a jet attached. I am also in the process of making an electric dredge and am learning a lot about what I need to do from you. I am not 3d printing though, so my craftsmanship comes down to what is at the local hardware store.

[@UtmostOutdoors]

I guess it mainly just comes down to selecting the correct size nozzle to drill... I've had success in the past by drilling a bunch of holes at an angle around an abs plumbing pipe, then fitting a water jacket around the ring of holes... but then here I've found a basic suction nozzle has the best performance so far and would be quite simple to make DIY. I like seaflow because of all the cheapo pumps they seem to be available globally so I can use what's available in Canada/USA as well as Australia. Best of luck with the project!

[@markstahl1638]

The one thing that I noticed that you didn't try was, with the double suction nozzle, was to have one of the two further along down the tube. Just a thought.

[@orpaillagetoutsimplement2462]

Hi, thank you very much for everything you made us understand 👍 Personally I would be interested to see a 2" dredge with the sluice on the surface, on floats and that it can also be put on its feet for places where there is not enough water for the dredge to float. Why not fix the battery on the dredge, and the pump is attached to the dredge but quickly detachable so that you are free to position it in the watercourse. Greetings 👋

[@UtmostOutdoors]

Great suggestions!

[@fittergrips2010]

You now got data for future builds with a suction nozzle . I played with a suction dredge a little . Spent most of my time clearing a clogged line . Might be a good Idea to figure a nozzle design that prevents line clogging with elongated rocks . And hose to fitting adaptor the avoids fitting sitting in side line down stream of flow . a gravel full suction line is very heavy

[@goldentroutprospecting1821]

I've looked at the goldibox and it seems to be a good idea for remote locations but it seems like it needs some Kyle like engineering to get it to the next level. I'm patiently waiting for the box testing to begin.

[@UtmostOutdoors]

I'm a long ways from a properly thought out complete recovery system, but I should have the electric plumbing sorted out soon...

[@rickabrams376]

Im looking to put together a electric dredge/ suction nozzle handle with on off switch for only metal detecting. something i can carry in one hand instead of digging all the time. looks like i have an idea but just have to figure out electric pump and battery combo that will float . cheers

[@filipvelkov5263]

It would be great to have a dredge with 12V pump. I'm using 12V 4700 GPH pump with my 25" highbanker and it works great on shovel but I really want a sucking dredge on battery

[@mohammednovalija]

My head started to hurt unbearably at the 5 minute mark - GOD BLESS THE FAST FORWARD BUTTON.

[@UtmostOutdoors]

Heeeeeeeeey! Your supposed to be watching other things until I'm back out and about looking for gold... :)

[@mohammednovalija]

@@UtmostOutdoors But then I would have missed the tidbit at the end that the Fast Forward button found. btw - have you done something with your hair ?

[@Graham_OntheGoldagain]

Very interesting. Have you gotten any Aus au yet?

[@UtmostOutdoors]

Not yet... 😞

[@illernpiller]

Great info, but since it seems you are likely gonna be in shallow water I would more look into a suction nozzle instead of a power jet.

[@illernpiller]

Learn to watch entire video before committing 😂

[@illernpiller]

And I would love to see you test a infinity jet. =D

[@brandonjackson1434]

Curious to know if a twist in the double jet causing a spiral flow projection into the tube would have an increase in suction and flow

[@UtmostOutdoors]

My guess would be any energy directed towards anything other than direct linear flow would be an inefficiency. So ideally the straighter the flow the better, otherwise the energy required to impart a spin would be removed from straight linear flow. I guess that could be tested at some point...

[@brandonjackson1434]

@@UtmostOutdoors that's probably the reality,good explanation,,but in my mind the vortex draws more water but my mind doesn't have a pressure regulated to actual pumps ability

[@brandonjackson1434]

[@BearlyOutdoors]

U.O., I think I understand a little of what your smart brain knows! A small floating sluice with battery in backpack would be super for my situation. I look forward to your ideas/ultrafine gold equipment!

[@wolfpack1384]

The 2 vids are up on my page I messaged you. Hey wondering how why the divider in the backside of your highbanker

[@UtmostOutdoors]

I had a look at the vids. I'm not sure the divider you're talking about, but assuming it's what I use to direct 50% of the water flow to a top level and 50% to the bottom level which runs in parallel. I just split the flow from to 10" wide hopper into two identical 10" wide sluices underneath. It's essentially a 20" wide sluice box under a 10" wide hopper, but just a bit more compact.

[@wolfpack1384]

@@UtmostOutdoors ah very cool thought it might do with flow rate I like it I'm not good at vids never really been up for it but hope to some day

[@eldin-j6b]

i thought that you could NOT dredge on the sask river, or any where in alberta. so where do you plane on suing this.

[@UtmostOutdoors]

I'm currently living in Australia where I also can't dredge. But I've wanted to pursue this as a thought experiment for a long time and hopefully I can figure something out for all the folk out there who can make use of something like this. The long term goal is to learn how the plumbing works in order to build a larger version that could be used commercially somewhere like Nome Alaska.
