Portable DIY Shaker Table for Gold Prospecting and Extraction
Вставка
- Опубліковано 14 жов 2024
- In this video I demonstrate a home-built, portable, gold-extraction shaker table for field use. I mix fine gold with black beach sand and extract it using the table. The results are presented.
Here's a link to a SketckUp drawing. It's approximate and does not reflect my current thinking on the best design. The rubber mat is not the same as the one used in the video. Please use it as a rough guide only.

I like your honesty in your opening comments. Most of us are just hobby prospectors. I also enjoy making homemade gold separating machines and gizmos. You are an inspiration for me to get back at my own gold projects.
Hi Scotty. Yeah, I love to try to make stuff and gold separation is fascinating. Good luck with your next one. -- Dave
Your video is the most enjoyable I’ve seen in ages... I just want to find some gold in my creek here in a very Geothermal region between Cobb Mt And Mt St Helena called Anderson Springs. I’ve got property with no cabin since the Valley Fire, with the deepest pool on bedrock that erosion has changed 8 seasons in a row, after virtually no change in my 65 yrs. grandpa built the cabin as his escape from grandma in the 29s and 30s...I had to make it my home in 2010. Grandpa found quite a bit while building the cabin and swore to me that I would find the secret ...I was 10! He told me in my 60s. I’m 65, and want to rebuild that simple life. Living in a Toy hauler is fine, but it’s a bit too tight, and I can’t have my trailer on my property without a dwelling. Gotta luv Lake Co Code Enforcement! My 39k had to be spent on renting in a tiny RV PARK,...That was NIT MY PLAN, lol ...such is life! Before I lose my vision completely, I want to have fun trying to chase a little dream. Lol😇 THANK YOU FOR YOUR INTELLIGENCE, YOU GAVE A DASH OF A SPECIAL “legend” hope!
Best of luck to you, Kitty!
i have just found your channel...and i have subxcribed beacause of your "all info "approach . im going to try to replicate your table...wish me luck
Hi bob, thanks and good luck. Be sure to watch the relevant videos before you start and please ask questions if you don't understand something. You can contact me at Orophilia.gold@gmail.com
Great design. I think the best DIY shaker table I've seen.
I just looked down and realized I'm wearing the same grey Columbia sweater as I watch this video. lol.
Very cool!
Excellent job 👏 👍 👌
I had given up hope for a small scale or should I say hobbie scale shaker table.
Nice job and not overly complicated.
I've been following Jason , Jeff , Dan and few others for some time . They are a wealth of information to those who enjoy prospecting .
Great video , thanks .
Thanks for the comment. Take a look at my latest video where I've changed to a bump-sluice type of table. It's looking good. -- Dave
Amazing!!! It would be great to have a manual on how to build one! Really amazing work!!
The portable power supply box looks like a happy robot! Lol! 🤔😎😆
Very interesting! Great build!
Hah! I follow all those guys! Your one smart guy. Thanks for sharing!
Pretty Slick! I had a rubber mat for flooring in a truck that i could modify . It had very small ribs across it. If I had something like a shaving razor to remove some ribs it would work real nice! I would have two batteries and charge them with a solar cell setup to swap out when I needed to.
If you make it let us know how it turns out. Good luck! -- Dave
Very nice build, great job!
Thats fantastic. Great work! I'm well overdue to make or acquire a wilfley table for our little plant. Thanks for all the detailed info.
Great design. Smooth and rhythmic movement. Thanks for sharing! You have a new subscriber!
Thanks for the sub!
That some great and informative channels you watch. Awesome table you have made, I would love to make one myself for computer chips
hey man just wanted to stop by and say nice table. i like the extras you did for the battery pack and all too its not a bad idea at all. if you decide to do a box for ac power for when your home you can always just use fan controllers from lowes menards home depot. or if you like your own wiring you can use rheostats aka dimmer switches if you didnt know.
also as for the flexors. look into scooter parts gy6 50cc or the 150cc the parts are dirt cheap and you can use their torque drive or clutch springs for your base. the 50cc stuff is pretty strong the 150cc is really strong and the 2 stroke stuff is inbetween. they may be a bit bouncier than the flat stock but will last forever and move more fluidly.
We've been beach mining in Nome Alaska for more than 10 years. We've developed several iterrations of a 12 vot portable mini-sluice for prospecting. Always looking for something better and faster. Your demonstration is very interesting. I admire your ability as a craftsman. I am not capable of building such a fine machine. How about a simpler solution? Have you thought about using an acoustic speaker and a vfo to drive the vibration?
That is quite an interesting idea! Yes, the idea with a sluice is to keep the material in a state of partial liquefaction, and the acoustically-induced vibration should do that. I'll give it a try. Sound like fun. -- Dave
I look forward to seeing how you cut the Neopreen and a supply list. Thanks as a fellow SoCal prospector.
Hi Jim. Greetings from SoCal. I'm cutting the grooves directly into Baltic Birch plywood. The process is faster and saves the cost of the rubber. Take a look at my latest version of the table. -- Dave
Great job love the tinkering!!!
knowledge is power. thank you for sharing my friend!
Very nice design, and workmanship
Definitely awesome and thankful this video popped up for future reference. Cheers mate.
Great video! l look forward to more of your ideas in action.
Great job on that table
Very interesting! I am curious about how much design you put into the shaking action itself? The asymmetrical gearing you show should produce an equal-speed back-and-forth shaking of the deck, but I feel there is huge potential in designing a shaking motion that is fast in one direction and slow in the other. Something akin to tapping a pan? I am only theorizing here, though. Thoughts?
Hi Kristian. Yes, I agree, there is some potential here for innovation. I'm trying several other methods of moving the table with more of an impulsive force. Asymmetry is the key. Thanks for the comment.
As long as the center of the motor axle is offset from the pivot point on the table, there is some difference in motion forward and back due to the geometry. It will move faster in one direction.
Amazing unit! Love the build and video.
parabéns pelo equipamento super simples e fácil de ser feito. gostei demais deste vídeo. Brasil rio de janeiro
Que bom que você gostou.
Great idea on the table.
Have you tried cutting 10 percent back on the speed of the shake.
Hi Steven. Yes, I've tried lots of different settings for the table. Thanks for the comment.
That was awesome!
I think the fine gold vs the sand and heavies is still not within the same "scale" though. For full separation you can't have a gold particle smaller than 1/2 to 1/3 the size of the largest heavy and the 1/3 is really pushing it. Try running it with classified material within this size ratio and tune water for that and I think you will be surprised.
Yeah good comment. I have a lot to discover about various types of material. I won’t be able to get out to the desert for another three weeks. I’m going to see how the apparatus really works
@@orophilia I just wish I had a goldsource anywhere near here.
I get to go to a goldcamp two times a year tops, and it's a 4 day stay with a 16 hour roundtrip.
Built my own vortex matting and classifying sluice though, and it works a treat.
The classification is really important to allow the shaking and water to handle the particles differently. Since gold is 19.3g/ml while the heaviest sulfides and black sand is up to maybe 7g/ml (tin sulfide 5.3, lead sulfide 7.6, hematite 5.26 and pure iron 7.8) a round-ish particle twice the diameter of a gold particle starts to act the same. Any larger difference and it's a random game of bounce the particles.
I've always been pondering some sort of screen system on a shaker table to automatically screen the material into very tight classifications so they can drop on different regions of the table with correct waterflow to separate perfectly. Would be beautiful to watch.
yes! that’s a nice idea. thx for the comment
I’ve been looking at the settling rates for gold and other minerals of various shapes and I see what you mean
Nice build, thanks for sharing
I would love to see you produce a tape of how to make the vibration device.
Commercial units are well over a hundred dollars.
I myself just cannot work out a suitable design.
EDIT : Oh , NVM - I asked too early - The tape clearly shows how you achieved the required movement.
hi Mohammed! I am on the road this week. Next week I will make a video of the motion stage with a new type of drive that I think has some possibilities. thx for the comment
@@orophilia I feel that whatever you post will be interesting - I Love what I have watched so far.
cool build, If going to the desert, I would take something that concentrates and does more production, then bring back the cons to your machine. It will not do as much production running desert material as you expect, i don't believe. I make concentrators, on my other channel, that would do much more production, Spike's prospecting Equipment! Great build and details! I mold ABS parts!
Yeah, you could be right. I have a few days off next week to check it out in the desert. I'll take the machine with me but I'll leave it at the cabin. I'll collect some classified material from various locations and run it through the machine in the evening. Great to know that you mold ABS! Thanks.
I've never clicked on a video so fast to find the link where to buy one of these...
Hey Chris. You are one of the folks that inspired me to make this. I enjoy your channel very much. I’ll be out in the desert in a week or two to see if it stands up and makes a good showing. After that I’ll help you build one if it works
@@orophilia mate if that thing works and you can make a consumer version I'll buy one off you no questions asked
Great video. Jason has a awesome channel.
This is fantastic! Thank you for sharing!!
Thanks, Skippy.
That's an awesome table thanks for some ideas
nice video toturial..... thank you. 👍
Great video! Thanks!
Finally a shaker table I could easily fit in the space my wife lets me have in the dog house 😯
Would you mind describing the neoprene mat you used?
Does the mat material have a big influence due to surface structure?
Example: Rubber can be very fine grain, neoprene can be rough (rough doesn’t mean bad per se, we all worked our pans for a reason).
Thank you, this is very encouraging!
Yes, the surface texture of the mat does make a difference, especially in the grooves. I finish the grooves with fine sand paper for this reason. I use simple neoprene mat, 1/4" thick.
Thank you for being specific.
I have a 3mm mat on my desk and two buckets of a nuisance to pan. You have helped me.
Could you put a run above the bar with a wet hopper at the top to do a constant small feed onto your current loading zone while you load the hopper twice as much but in intervals? (If that makes sense)
Yeah, totally makes sense and that's how I'd run it in mini-production mode.
Sangat kreatif,saya dari indonesia saya ter inspirasi dengan ide ini
"Very creative, I'm from Indonesia, I was inspired by this idea" Thank you so much. -- Dave
What kind of motor mount did you use please? Looks like either delrine or a 3D printed mount. Looks like it would absorb some of the shock from the acentric coupler. Thanks
I bought that motor from amazon, I think, and it came with the motor mount. I've made other motor mounts out of Aluminum plate, Delrin, etc. They all work.
Nice build!
Perfect for a gallon of beach cons!
Why is the battery voltage 8 volts? I thought the motor you are using 12 volts? Thoughts? Thanks
Hi Dennis, Both the pump and the motor are 12V devices, but I use the voltages to them to adjust the rate of water flow and the rate of shaking of the table. So, I typically run the pump at 8V and the table at 14V. That gives the best overall performance. -- Dave
You got my subscription let's go
TY great video!
I need this badly
Very cool.
I live in a town that only exists because of gold (Thames New Zealand) and yet the law prevents me from even panning in my own backyard with my own water and my own dirt.
I have to satiate my gold fever vicariously.
Nice my friend real nice
I really enjoyed your video
Good job. Where i buy this shaking table
I'm sorry, the table is not for sale at this time. -- Dave
What a nice job
Wou bee very interested in your thoughts and expertise on this matter.i am new to this and having trouble .if I could send you a sample of material you could keep anything you extracted for your advice and knowledge.
Hi Billy. I would make a video of the analysis process, so I would need a description of where the material came from and a photo or two of the place and whatever other information you could provide. I would do a fire assay at a minimum. No accuracy guarantees.
@@orophilia can I get information as to where I can send the sample to as well as how much of a sample is required.i am really interested in your knowledge and to put my curiosity to rest and have affirmative yes no
What about putting two shaker tables in a diamond configuration but with two feeds?
That should work but be aware that the load on the motor and springs will change. Some experimentation will be necessary. -- Dave
@@orophilia I didn't see that there was any springs in the system but I get what you're talkin about.
@@dennishedrick5308 The flexure supports are springs. -- Dave
Excellent just subscribed👍⛏️🇦🇺😊🙋
good job really nice
Awesome video, can you try running ic chip ash to test it out?
No, sorry, I don't have a source for incinerated ICs.
Very cool
Roast and morter and pestal?
Yes, that would work if the gold is trapped in the sulfides.
Where do you buy the 5mm drill bit? I have searched everywhere. No one carries it.
Hi Wayne, The nearest US size would be 13/64. -- Dave
But a nice build, are you some kind of wizard, thinking about the switchboard, and the whole built, diy or a lot of education
Some of both. Thanks for the comment! -- Dave
nice job.
where can I get the portable battery supply? or do you have a parts let on how to make one
Jackery Portable Power Station Explorer 300
Very nice...
you didn't think sir to try instead of water for example strong salt solution, won't the separation go faster or more complete?
No, I haven't tried that. Interesting.
Only on midnight under full moon ......😉😊 excuse my sense of humor and little sarcasm .....
We try a lot of additives .... on the long way of over 40 years ( first hook 1980 ) experimentation .. wich become slowly experience ......please read my comment above .....

What is the table feck or the rubbermath, what is that from, and how to get it,?
The rubber mat is made from Neoprene, 1/4" thick. It's available from Rubber Sheet Warehouse. -- Dave
Wow
Nice work

I like that design it's very interesting
Thanks, Eric
Very nice 👍
looking for a set of plans for this and the miller table...

Im desperately looking for small table , for gold bond wires🤔
Gold wire bonds are difficult for a shaker table because of the large surface area.
Do you have the motor specs and part number for the shaker motor for both tables please? Thanks

@@orophilia Thanks
Can I please ask if you would build me a table.
I have a table I bought for thousands and yours works way better
Thank you so much for the complement, Raddam. I don't have the facilities to make the tables. I'm hoping that someone much younger will perfect this type of small table and make it commercially.
Does anyone have measurements for the "grooves"? Are they all the same depth?
Hi Patrick, The grooves are 2 mm deep and 6 mm wide, spaced between 12 mm and 18 mm, depending on your preferences. -- Dave
Price for one of your shaker table and shipping cost to Ohio?
Hi Gary. I'm sorry but I don't have a way to manufacture the table. -- Dave
@@orophilia can you make me 2 mats for the table if so how much for them and shipping cost to Ohio.
@@garymiller6269 Hi Gary, Sorry, I don't manufacture anything. -- Dave
Two Toes is a good channel too,, Fyi...
I'll check it out, thanks.
Not trying to pic shit, just give you a heads up and tell you Aluminium will work harden so it will crack, you can either change to stainless steel or just keep replacing all 4 of the Aluminium if you see one crack, but I would take some with you at all times because you know it will happen while your away from home.
Hi Gavin, I've switched to Garolite for the flexures. Garolite is a trade name for epoxy-fiberglass and should last more than the life of the table. It works very well. You can see it in action in my latest table video.
@@orophilia Yep just watched it, I know bugger all about epoxy-fiberglass so was going to keep my mouth shut. Metal is what I have worked with for 40 years, I saw something that could be a problem and gave you a heads up, I glad you found something better.
@@orophilia Oh hope you don't mind but I sent Chris of Vo-Gus Prospecting a heads up about the miller table you made.

ສະລັກຈິດ
Suspend the water bar detached from the table
Why milligrams man wtf
If I understand your question, you're asking why I use only 50-100 mg of gold. Well, that's more than enough to get the job done. I'd rather use less because that would be more representative of the actual concentrations that we mine. At 10 ppm, using one kilogram of beach sand, we would expect to get 10 mg of gold. In the end, it's just a test of the efficacy of the table.
80% needs some tweaking . Was wondering if you have seen this video ua-cam.com/video/bZxSqqP5hpc/v-deo.html ?. Zeroing in
hi Bart. for heavy black sand extraction I think it’s pretty good. yes I’ll be tweeking it. thanks for the link!
High there !
First of all ..... I have to disappoint you ,- and the whole hobby mining community ......
There is for "average" person almost no chance to build a really working shaker table for fine Gold .....
Why .....?!
The physics and behavior of concentrate melange with fine Gold is ( and that with a obviously simpel
gravitation influence ) so difficult ,- that it needs a real S-table design ( even there with preparation of
the material) to separate the Gold in ONE "strike" !
These table comes with quiet some costs !!
It will help to read the "bible" of "Mineral Dressing" ( Taggart) ....... ( 1000 pages)
But to the next disappointment ..... there is no majorwise news since 1954 ......
We watch Jason for a while ... and his table have a different setting then yours .....
And obviously not even on the point ....
He is realy good in his work ( may we try to arrange a meeting at his place ..... will see )
Your handicraft is good ....so the critics are all around the principle of the hydro mechanical execution ..
The details are not easy ,- and easy to build .....
Your assumption ,- with the aluminum "spring" support , is not correct in the way of purpose ....as an
example .... it is way more to it .......unfortunately 🤥😪
Don't hasitate ,- if you have questions
Greetings from the team
Hi Rigel and the Team. Can you please give me more information about who you are and what interesting stuff you're working on? The table that I built works well in certain situations and not in others. I don't think either of us are surprised by that. I've been able to separate gold particles down to 250 microns (60 mesh) from black sand and heavy sulfides using the table, but recovery rates drop for gold particles smaller than that. Of course, it also depends on how the table is set up and used, and how aggressive the separation is. As you know, I don't manufacture the tables nor do I claim that others should make one. I don't understand your statement about the Aluminum flexures (springs). It works as I've demonstrated. The shaking rate, shaking amplitude and water flow rate and distribution are quite important.
This is a YT channel for entertainment only. I make no other claims.
I'm looking forward to hearing from you! Thanks for the excellent comment. I'm always interesting in learning more from the folks that make this their life. -- Dave
@@orophilia Ok .... where to start .....
You know the different of a Holman table and a Wilfley table ?
It have something to do , with the stroke ,- the deck surface ,- speed and angle ......
We can handle ,- as an example,- 230 mesh = 0.063 mm ( 63 micron) pretty easy ..... in one work process ...( means ... the Gold is meltable ,- and can be poored..... )
Dave ... unfortunately my wife is calling ( and what that means ....you know hahahahah)
I get to it tomorrow .....
Greetings
@@rigel1176 I know both tables. The Holman table uses a sawtooth waveform and the Wilfley is more sinusoidal. There is a company in the UK called Holman Wilfley. Their products look quite decent. I'd love to know how to make a table that handles 50 micron gold. Thanks! -- Dave
