This is amazing!
I don't know Alan, from the looks of what you had recovered wet washing I would say you had 90-95 percent recovery with the dry washer. I ran a test once with a puffer and took what came off the drywasher sluice (about 2 five gallon buckets) and then ran these tails thru a spiral wheel. Got 2.5 gold pans of black sands that I hand panned. Got maybe 100 tiny meaning sub 100 mesh pieces from the black sands. If you put them all together you might make one of the larger pieces the dry washer caught. If I had spent the time just continuing to run more material thru the dry washer instead of messing around with the spiral bowl and hand panning all that black sand I would have ended up with 4-5 times more gold than I recovered. But I was doing a test to see how effective the dry washer was. The only way to really determine the percentage is to weigh the test results and compare. But to me your mods to the drywasher was impressive.
Thanks for your comments John ! Glad to hear from others, and their testing. Yeah, the screen method seemed to help improve recovery. Did you classify the material down to about 25-50 mesh before the spiral ? I've never had much luck with fine gold on a spiral. I'm a Blue Bowl guy. Lol ! The type of material is a factor. Dry stream gravel is best. Unfortunately, the dry washer can't recover much from gooey clay, which is what I'm currently encountering. Almost everyone out here running volume is wet for that reason. Should have seen the hard chunky clay I was running with the wash plant today. Whoowee !! Best of luck to you prospecting ! 🤠⚒⛏👍
I really have been looking for guidance almost too long now...and here you are,prayer answered
Thx for posting! Very interesting video!
Thanks for watching ! Seems to work quite well.
It's a true joy to watch a professional explain things to the masses. I just bought my first drywasher. As soon as it gets here, I plan on taking your advice. Thank you for your videos.
Thanks for the kind compliments Ed ! Wish you the very best in your prospecting adventures with that new dry washer !
I hope to hear your from results, thank you
Hi Allan, I'm a professional prospector in Western Australia and run a large dryblowing opertion..this is a very interesting solution to a well known weakspot of constant air. It's got my brain going....nice work.
Thank you for the kind compliments mate ! I checked out your channel and subscribed. Wow, you're out in the middle of nowhere ! Is it difficult to bring in water ? Because water will substantially improve recovery compared to air. If get time, watch some of my wash plant videos where I'm able to recycle water effectively. Currently, I'm designing a new wash plant that will be trailer mounted and increase water savings by 20% compared to my current unit. Let me know if I can help. My email: allan.goldmining@gmail.com
@@allansgoldmining Hi Allan, wet plants up here are possable and we run a wet operation out at our open cut mine.When air is run right the recovery off a dryblower can get very close to wet recovery. Gravity circuits in general will only return 50 - 60 % of free gold. Our dryblower works alluvials and needs to be highly mobile....get in..process 10 000t and move on...no time for water.
great idea and common sense. that's exactly the reason I always have to haul water. now im going to have to modify my dry washer. thank you!
Thanks for the compliments Norm. A wash plant is alway better, however, this technique helps bridge the gap. Good luck with your prospecting adventures !
@@allansgoldmining Hi Allan, love your videos. I moved to AZ a year ago and would love spend time with you providing free labor as a way to learn for myself. My wife thinks I’m crazy, but I see it as a fun way to spend time with some cool people and learn a very cool hobby. Let me know if you want to get a coffee sometime.
This video gets my gold brain going. The screen/damper design test provides: in-depth
informational engineering edutainment. It is! much better than Cats
Go for it Johnny !! Fun project and works good !
Revolutionary...as expected! Except on my first pass of anything... wet or dry (no matter what) I want to catch all of the black sand.
I will use any and every trick up my sleeve (including magnets) to catch the black sand. (Wet or dry... dosen't matter). In a sluice box I use black sand stuck to magnets to catch the fine gold.
Anyways... I'm jumping up and down right now because I know how much large mining companies love ultra fine gold and how much weekenders hate black sand and just want to get rid of the stuff and just get the gold.
Normally fine and ultra fine gold recovery is beyond the scope, ability and interest of us serious weekenders... but not anymore.
I want to start a new TV series called. "Leave it to Allen!"
Thank you ! Glad you enjoyed the video. 👍
Very informative thank you!
Aqua Donkey Prospecting approved!
Glad it was helpful!
Greetings Alan, What a great upgrade ! My dream trip still about 18 mos away includes a few weeks in Arizona. I can't wait ! Thanks again
Thank you for watching. Good luck to you. Find some nice gold !
That was very good teaching. Most folks just want to judge by gold content. They are not wise. This is a teaching video ! And a dam good one from what i see. I love that mini wash plant too!. A vibrating screen will also help break up a lot of clods, dry trommel, mini garden high speed rototiller. These all will aid in a better recovery. As does the flatness of the recovery box. Like you said, depending on your targeted size of gold. The more dirt ya run the more gold you can take. Nice job thanks for taking the time to make this video! 😅👍
Thank you for the awesome compliments La Deda !!! Glad you're enjoying the videos ! My goal is to help educate folks so they can enjoy the prospecting experience. Also give talks to gold clubs too. Hope to have a few more videos this spring. Currently, designing a trailer mounted desert wash plant that will be very easy to set up and use. Hopefully get more gold too ! Best of luck to you in your prospecting adventures !! 🤠⛏⚒👍
@@allansgoldmining nice! Yeah i teach gold clubs how to detect and recover small even sub grainers. Its those tricks if not taught most folks will never find it. It takes years to discover them on your own. I have trained several dozen and in return i get invited to their "played out claims" then we start pulling gold! Even multi grammers.! The payback is so nice! Keep up the good work! You will feed those that are hungry for sure!
That's awesome. Maybe I should take one of your courses ? I have a Gold Bug 2 for many years. I really like it, and found a few nuggets. However, I'm really thinking about the Gold Monster or Equinox 800 with 6" coils. Seen some nice results.
@@allansgoldmining both are very good machines! I use an older goldbug II and the sdc 2300. That equinox is a good machine in trashy areas! You can fin a small nugget under an old rusty nail real clear as day. Yet it doubles up as a good coin machine too. The equinox will find subgrainers. But the older 5 diggit serial number goldbug II is the most sensitive machine out there! The gold monster is ok but i wouldn't trade up for it. The perfect pair is the GreyGhost headphones w/ the GB II your take will increase a lot! You wont be able to hear your buddies talking but your focus will be razor sharp! And thats very important for small gold and drywash tell tale nuggets. 👍 GB II W/ 6" COIL, GREYGHOST headphones. The gold monster is cool because it has excellent discrimination. But the goldbug is slightly more sensitive. I have found gold down to 1/20 of a grain. Also when the sun is setting the goldbug quiets down and becomes very sensitive almost supernatural!...
@@ladeda7033 thanks for the huge advice ! I'll have to check out the GreyGhost head set. I just have a cheap set. I have the old Gold Bug II. Bought it over 20 years ago. It has a 10" coil. Been thinking about a 6". My friend has been very successful with his GB II with 6" coil, and EQ 800 with 6". My area is full of trash from the 1920's. My friend finds those nuggets under trash with his EQ, I can't compete. Lol !! However, if I blade the trash it's easy pickins. Last year found a little flat nugget with a hole in middle. Little donut. Lol !
Very good Allen, thanks for sharing a really good tip.
Just saw you on Jeff Williams channel. Great small modification, I just bought the screen to try this is out.
I'm sure you'll notice an improvement in recovery. I was operating my dry washer last weekend. Got some nice pieces and lots of fines. Good luck to you in your prospecting adventures !
Awesome video. Always a learning experience with gold. Good job!!!
Thanks ! Glad you liked the video. Good luck in your prospecting adventures !
Seems like a puffer would do this by the very nature of the bellows design. More air being pushed through the top of the riffle tray than the bottom due to the increased volume of air at the top due to the tapered bellows.
Maybe ? Run some tests. Post a video of the results. In general, a vibro static machine has a slight advantage.
Very interesting. I like how you kept it simple.
Nice!
Don't know if your still watching the comments. My question would be would it not be better to preclassify the material before putting it through the dry washer? Get out everything #4+ (and metal detect that to pick up any nuggets, and only run #4- though the drywasher, turning down the air flow to minimize the loss of fine gold. Since you don't need to blow out the big stuff, you shouldn't need as much airflow.
Hi Michael. Thanks for your question. Yes, you're idea would work as well. The screen idea, attached to the dry washer, permits the operator to classify material "on the fly." Best of luck to you in your prospecting adventures. !
Great video.
We have just completed the field testing of our new Airwasher plant.
Recovery rate is above 90% in the capture range, 1/2" minus to 30 mesh minus. NO box, continuous dual output, save port and reject port. Rejection ratio is approximately 25 to 1.
Adjustable capture range. Slowing down a bit, will capture the 50 mesh minus but the rejection ratio with drop to 20/1. This new system is designed for heavy mineral sand mining. We have closed down our manufacturing and sales, opening a mining operation in Nevada.
Good luck to you ! Hope you find lots of gold !
Never have dry washed yet. But this is so cool, I will do this when and if I get to do this someday.
Completely different experience. Hope you get around to try it sometime. Gotta love the dust !
Interesting modification. Your mod is similar to an "underflow" sluice box on a dredge. I may have to try it sometime. You are a natural video maker and your narration flows well.
Now a suggestion or two….
I don't understand why you don't use a magnet to carefully remove all that black sand when doing your cleanup. It will make the process so much easier. So will classifying your cons before panning.
Your experiment and results are valid only for your particular dry washer and material. You can't apply your results to all dry washers with varying airflow, etc. out there processing a huge variety of material and gold particle sizes. If you want to take your experiment further and then make your claim, then you will need to spend the time to process material from many different areas with many different dry washers.
I wonder if the bellows type dry washer would benefit from your mod?
Great video.
Hi Nick. Thanks for your compliments and thoughts. I don't like to use a magnet to remove black sand from concentrates. The filings tend trap fine gold. Tapping the magnet helps a bit, but not completely. The panning in this video was for quick demo purposes. Generally, I take all the cons and classify, then run through a Blue Bowl or Maverick Finishing pan. These effectively separates the black sand.I believe the screen technique with work well for all vibra static dry washers. Just a matter of adjusting the air volume and riffle angle for each condition. Not sure how well this idea will function on a billows system ? Hope somebody out there can test and report. Would be interesting.Currently, I'm designing a dry wash plant that will classify material through a dry trommel, then flow onto separate dry washers at different rates, air flow, and angle, to move volume and improve recovery.
Very nice sir.
Ur really good teacher or explainer very simply explained n understand great job sir my salute to u especially
Thank you for your kind compliments. Wish you the very best in your gold prospecting adventures !
Right side of sluice (if you're standing at the discharge end and facing the dry washer) has a lot more material flowing through than the left side does. That loses quite a bit of gold as well due to not being perfectly leveled (side to side) and perfectly balanced. Great idea with the screens tho man!
Thanks for watching ! I'll try to get it more level next time. Lol !
Hi Allan..
Fantastic setup..
Next step you can use Borax .
For recovery instead of mercury..
Thanks for sharing your knowledge.
Cheers TONY.👍🍺⛏🇦🇺
Mercury is safe if one knows how to manage it properly. It's not for amateurs by a long shot
Allen, if you tap the top edge of the gold pan it will force the gold up to the top edge where you can use a snuffer bottle ; this is called the " Blueberry Bounce " !
Problem solved. I use a Maverick pan for the past few years. Check my latter videos.
I most appreciate your posting this. I've watched your video on your washing op and really learned a lot. I need to watch this further. Perhaps you answer the question down the line. What about flour gold, I mean the really fine stuff, which is what we have on our claims? I think the words you were search for (50-cent geology terms) regarding a large iron particle vs a much smaller gold particle is "hydraulic equivalence". If words matter. Certainly specific gravity does.
Hi Thom. Thanks for watching my videos. Much appreciated ! Yes, the wash plant is the best way to recover fine gold, without going overboard and making giant Blue Bowls or Miller tables. Even with that, some gold at -200 mesh, or finer, can best be extracted by leaching. And that gets costly ! So, the values have to be there to make it worth it. A dry washer is at a disadvantage because of the physics. My little screen technique helps, but not as good as the wash plant. Thanks for your comments, and good luck prospecting ! 👍🤠⚒⛏
cool video , keep up the good work
Thank you. Best to you and your prospecting adventures in Deutschland !
Nice work, mate.
- I came here because Ash Jeff Williams recommended you :)
I saw the other video too, but forgot to leave a comment ... Sorry.
Thanks for watching. Good luck to you in your prospecting adventures !
You are a thinking man. a box is not just a box to you, is it? I like the way you think amigo, right or wrong you challenge the norm!!!
Thanks Richard ! Yeah, I've always done that all my life. Lol ! I'm an inventor at heart. Check my latest videos on the Gold Rattler. It my latest creation. 😊
Allan, you are a BIG Solution to many us, this is a industry nobody wants to help,but to enrich themselves, once again thank you... especially when you are new and know nothing, if possible what is your take on other commodities like copper, I m new I haven't even try for once to prospect or anything,first I want to educate myself and then take the step,that will be very soon, I live in a area of rich copper deposit,I want the ground experience...🙏🙏🙏
Thank you again for your kind compliments Prince. Glad to help those in the prospecting community get started building equipment at low costs to extract gold. I also recommend "Ask Jeff Williams" RUclips channel for prospecting tips. He's very entertaining ! And you will learn much. I have worked with copper. Processing and extraction depends on whether you are dealing with oxides or sulfides.
Thanx Allan,I will follow him as well, i will appreciate it if you you can tip me off on both sulphur and oxide,thank you
Cool
Enjoyed your video, technique, and comparative elements very much! My machine would benefit from your example, thanks.
Thanks for the kind compliments. Wish you the best in your prospecting adventures !
Allan thanks very much... I subscribed here. If you get some time stop bye my channel. It's new and I would appreciate it. Just getting started really. Cheers and best wishes, Aaron.
That was a GREAT video , l have an old Keene Dry washer without a shaker , it has a 3 1/2 H P Briggs and a big blower , How do you figure out how much air to use ? And what angle to set it up ? Then I just have to find some ground to work. Thanks. TANK
Surface area also plays a key roll… i use a Royal dry washer and it looks like yours has half the surface area as mine which means yours will have a greater output of air pressure.
I run my blower on idle and it seams to work perfectly.
I do like you idea and I may try it just to see how much I’m dumping.
I also use a metal detector to find any gold that may have jumped the riffles in my tailings.
I like your set up.
Hi Fred. My blower runs about 1/4 throttle. Surface area is definitely important, considering the volume of air being delivered to the unit. Give it a try and let me know how it works for you. Best of luck out there ! 🤠⚒⛏👍
Every time I see Allan I see Benny Hill: It's the check shirt, jeans with braces, cravat and hat combination that cracks me up. (No offence or malice intended; but the first time I saw these videos I had to check to see if I had my glasses on, sorry!)
Ha ha !! That was my nickname during my college days ! Had a lot of fun with. 🤠
I watched 3 times and paused several times. It looks like “by weight” you got 70% “as is” and your modifications look like pan 2 was 15-20% and only looks like 5% (leaving the usual 5% even the sluice misses) as super fines look like a lot but don’t ever seem to weigh that much. It sure looks like you are pretty close to 90% recovery with your modifications. I would like to see you run a good size sample through your modded dry washer then run the tailings through the wash plant. Keep the cons from both and take them home, clean, dry and weigh the results. Thanks for sharing!
Hi Chris. Thank you for your analysis. Unfortunately, the camera does not have the resolution to visualize all the fine gold. So its hard to assess on the video. I think you are pretty close though. In this demonstration, I ran four 5 gallon buckets of material. Yes, a larger run would improve validation. If I get a chance this summer, will test with more volume. Thanks for watching, I appreciate it !
Oh, one more thing. The material I ran was tailings from 1920's dry washing. The material was well broken down. The virgin ground I'm currently working is caliche with chunky red clay. So, the wash plant will have a better edge on recovery.
I really enjoy yours and Jeff Williams desert prospecting videos. The collaborative video was funny! Jeff was like a kid in a candy store. I think it’s fantastic you have come up with a way to help people who have to prospect with little to no water. I agree that your wash plant with the dewatering trommel will work much better assuming someone could get even that much water to where they are working, but for those that can’t use a wash plant, 90% recovery is pretty amazing.
That’s cool, I’m glad you are still getting good gold out of the old tailings! It’s also really cool there is still virgin ground to be had.
Thanks Chris. Glad you liked it ! We had a fun time filming that one. It was totally impromptu, and we just let it roll. Yeah, a lean well tuned dry washer can obtain a good yield. I still use mine for prospecting all the time. I'll let you in on a "dirty" little secret (but don't tell).... I LOVE dry washing ! It's a lot of fun, and prefer the dust over mud any day ! Lol !
Just got home from a weekend on the claim running the wash plant. Got a nice nugget, a few pickers, and a bunch of fines. Made a video. Hope to publish it in a few days.
Why not line the bottom of the hopper or the head of the riffle tray with magnets to collect the black sand and gold (by getting stuck in the sand) allowing the separation process to be more efficient. The screen idea is genius, btw. Great tip!
Audrey, thanks for complements. The folks at Snake River Products have a device called Clean Gold, which utilizes magnetic strips to create a black sand riffle field for trapping fine gold. I use it on my wash plant sluice. Works great on fines. However, the same concept doesn't work well on air or dry material. Will keep trying though !
This shows that rerunning your tailings helps improve capture when drywashing. Have you compared running it un-modified twice? That might give you much the same results!
Hi Kevin. Thanks for your question. I did test a second run and only found a few specks. It's what you would call "Random Change." Running tailings a second time though a dry washer or sluice will yield gold through this effect. Best of luck to you prospecting.
Excellent, that adds more credence to this idea!
Use magnets to stall the fine gold in a fast flowing tube out the back.
Might be worth a try. Had something similar on the sluice called Clean Gold. It was marginally successful.
@@allansgoldmining There is a man who says he will design and build a magnetic sluice unit for free except for the travel, hotel stay and food, not sure if that is only for Canada and Alaska or for any place gold exists, but from the looks of those diggin's you are working on at the moment, it would probably not pay off.
Sorry, I bout know you language. Aim from it's Kazakhstan) ..
Your big jobs end nice video. Bravo.
Thank you. Good luck prospecting gold.
GREAT VIDEO!!! best drywashing video on youtube! That should work on my puffer drywasher to...right?
Thanks Shane ! Glad you enjoyed the video. Not sure how well this technique will function on a puffer model ? Give it a try and report results. Maybe make a video ? Would be interesting indeed.
WILL DO! i have a bunch of gold prospecting videos on my page if your interested...Thanx again!!!
i love your trommel too!!!!!
I just watched this video again and picked up a couple things I missed the first time around. The spruce is to support the screen high enough for the flow to continue. About how high from top of spruce to top of riffle?
The spruce stock is 1/4" square. So the gap between the top edge of the riffle to the underside of the 20 mesh screen is about 1/4".
Allen, have you shown these modifications to Keene engineering? if so, are they going to incorporate these changes? If not, would you consider manufacturing and selling the screens?
Thanks for the kind comments. If Keene or Royal present a new line of dry washer screens, you'll know they watched the video. Lol ! Honestly, I put it out there for everyone to share. Most of my effort are towards a marketable portable wash plant. Appreciate you watching. Best of luck to you prospecting ! 🤠⛏⚒👍
@@allansgoldmining Thanks for getting back to me Allan. I have just asked Keene to quote on the mini drywasher for me. I have recently retired from the Army and settled down in Dunolly, Victoria so I am literally living on top of gold. Thanks for sharing your thoughts on improvements I shall incorporate them in my new plant when it arrives.
Would a puffer/bellows dry washer benefit from this modification?
Hi Bob. I've had a couple folks give it a try, but not too successful. I think the problem is the bellows angle. Due to its triangular hinged design, higher air volume occurs on the upper riffle board, while the lower section less.
YeeeeeeeHaaaaaaa
Hi Allan, I checked out the Lowe’s buckets. They’re very rigid. have a question about the trommel. Do you have an idea on longevity and which part/s do you see wearing quickiest (so I’d keep spares)? Thanks, Terry
Honestly Terry, I've only run about 20 yards through the system so far, and haven't noticed any excessive wear. I performed a complete inspection last month. I'm quite amazed how well things are holding up ! I speculate that the plastic bottom plate inside the hopper would be the first to go, considering it takes a beating from all the rocks being dumped on it. However, it's holding up too ! This past weekend my waterproof bilge pump died, so I had to replace it. Somehow water leaked inside the motor compartment through the power cord insert, and shorted out and burned the brushes. It was sudden and unexpected. I plan to raise the pump high enough out of the water to keep the cord dry. That's the only issue so far.
HI Allan, Sure would have liked to see the screen under your screen!!
Hi Dan. Not sure what you mean ? The screen over the riffles is a single 20 mesh. No other screen. The screen on the underside of the riffle tray is 75 mesh. Both are well demonstrated in the video. Hope this helps.
Do you have blueprints for your wash plant/tromal that you built for the 37 gallons an hour ? I'm interested in that plant. It's small and looks like it could be compacted to fit any vehicle and possibly, could be pulled with an ATV .
Hi Alan, thanks for the great video, free knowledge is always appreciated. I live in Arizona and I have a quick question but not about your drywasher. Does that type of mining require a claim to be held or filed before you can prospect it? Any tailings, unless they're on private property, are fair game?
Hi Chris. You don't necessarily need to file a mining claim in order to use a dry washer as "Casual Use" defind in BLM regulations. However, you need to research whether the ground is open to mineral entry, and where there are legal mining claims posted. Both the State of AZ and BLM have PDF files you can download online that will give you all the info regarding prospecting and filing mining claims. I personally have mining claims. Also, if you visit "Ask Jeff Williams" RUclips channel, he has over 300 videos on prospecting, including how to file. Good luck prospecting !
Thanks for this video. I'm going to give this a try. I'm curious if you think a screen over the entire box would work? Do you think this would increase the capture rate of the fines even more? The risk is losing bigger gold but you could metal detect the tailings. What are your thoughts?
Hi Josh. I haven't tried covering the entire box. Give it a try and see if it works. My thoughts are you need a portion of it open to capture larger pieces of gold. Best of luck to you. Keep me posted.
Did this guy stop off at the fancy dress shop on the way over! Haha. Well he's a tryer ill give that to him.
On the other one, I don't have any leather bellows hanging around so what about bagpipes hmmmm!
Never tried this experiment on a bellows unit. Not sure it it will work ? Only vibrostatic machines. The hat and costume is my trademark.
What is the best angle to run your riffle tray at. Your first clean up has way more black sands than I am catching. And I am losing alot of fine gold right out the end of the sluice box. And might I be feeding my material to fast. Any help would be greatly appreciated
Thanks great video
Red
Hi Red. Thanks for watching this video. There's no real angle to set the riffle board because of so many variables, air volume, feed rate, material type, machine type, etc. But in general, I like to start at 12 degrees. I feed at a rate that I can barely see the top of the riffles. Don't feel bad about losing fine gold. The physics involved makes it difficult to recover, unless you have an over abundance of fine gold you're working. Dry washers are a good prospecting tool. However, when you find a really good spot, it's always best to bring in a wash plant to maximize recovery. Check out my Gold Rattler videos if have time. Best of luck to you !🤠⛏️⚒️👍ruclips.net/video/3xLrOrDDbgc/видео.html
Have you thought of placing strong magnets onto the vacuum hose while you are cleaning the screen.
When you have cleaned remove magnets and black sand will fall out of the vacuum hose.
Should take out alot of black sand.
The problem with static magnets is that particles of gold become trapped within the magnitite filings. I currently have a better solution called Spin It Off. Pulls off magnitite, but leave the gold behind. Works perfectly. Check out their videos. It's amazing !
I use magnets for that reason but afterwards I collect the black sands as they do hold tiny and microscopic gold particles. I then process the black sands with Mercury. Mercury is PERFECTLY SAFE if you know what you're doing, wear proper PPE and NEVER slack on having a safe protocol!
Being a Arizona prospector for 28 years, this was very interesting to me. It would be well worth the test. Very good explanation. I subscribed to
your channel. Please do the same for me and continue doing what you do.
Thanks for the compliments Chuck. Always fun to converse with a fellow enthusiast. Give it a try and publish a video. Looks like you picked up a nice dredge. That would be fun to take to Nome. Best wishes to your prospecting adventures !
Hello sir, new to the desert and failing; I tested my puffer with fines in Idaho and it looked ok compared to wet washing. I'm using microfiber cloth which generates a lot of static. Just wondering if there are pitfalls I'm unaware of aside from durability. Are furry materials avoided to ease clean up? Thanks for the content! (If you find time to respond, I'm very curious as to what a decent grade of bank gravel in a wash would be and how large of a sample should be taken, more so than the cloth, thank you.)
Thanks for your message. Probably need to do testing for efficiency and durability.
I’m thinkin 2or3 more feet of screen to run the fine stuff over would up your % a bit?
Thanks for the ideas Joe. That might work, but make for a long dry washer. Another option might be to add a series of little riffles on the same board. After all, we're attempting to catch fines, so replacing the existing 1/2" riffles for a bunch of 1/4" might do the trick ? Will have noodle on this more. Best of luck to you prospecting ! 🤠⛏⚒👍
do you have a recommendation for a vibration motor for my top hopper that will work on the large royal without spending 100$ 12 volt?
That's about the going price. I bought a 12v on eBay a couple years ago, and paid $85. I would keep an eye on eBay for a deal to pop up..
Always make sure to turn off your autofocus when shooting close in shots ;)
Phone camera does not have that feature.
Hi Allan, how are you?
the black cloth in 9:48, this is a nytex nylon??
Thanks for info
Yes it is. Can find it in most fabric stores and Walmart.
I've been told that a magnet will separate the gold from the black sand, presuming that the blacks and is like magnetite
Yes, it can. Unfortunately, not all black sand is magnetic. I love my Spin It Off magnetic separator. Good invention ! 👍
Cant it be that the fact you ran the material twice is the reason for more capture? I would like to see material with guaranteed Au amounts ran thru both systems. NOT Dissen, just pointing out not fair comparison. outside that, it does look like screen helps, just not sure how much. cheers and thanks
As I mentioned in the video, there is gold trapped in the upper riffles due to "random chance." Anyone can re-run tailings through their dry washer and collect a small percentage of gold on a second pass due to this property (Physics 101). The physics remain the same, until there is a change. That's where the 20 mesh screen and reduced air volume come into play. The gold is trapped on the lower riffles because the dynamics have changed on the second pass. Obviously, this gold wasn't recovered on the first past because of the inherent physics of a dry washer. By modifying certain features, the physics and be altered for improved recovery.
Random Chance isn't intelligent or physics lOl, unless yor a Newt/globalist. first pass caught specks smaller and equal as second round with screen. perhaps/ Obviously,,, percentage of Au against volume would better represent advantage' of screen and baffle compared to inherent Preponderance and Obvious,, Dipole properties. Confirmation Bias is Bitch.
Think what you want. The physics are undeniable.
hi.(sry for my bad english) are you sure you don t lost large gold parts, trying to find the smallest one? did you test without modification to see if you don t find large gold part after the middle of your washer?(i think your idea need this experimentation because if, when you find 0.1 gr small gold, you lost 0.2 gr large one, you understand it would be less interesting)
Any gold 0.2 grams will easily trap in the first riffle. The dry washer is very efficient in that regard. I have experimented with this for quite some time. I run all my dry washer tailings through the wash plant, and have never recovered gold greater than 100 mesh.
So c'mon lets go!..... oh shit, sorry wrong channel. oh well, at least you have another sub!
LMAO !!!!
I watched it when it was first launched. Lots of good fun making it.
Just a thought, I do not mine myself, but I am interested. Why do people not design their machines so that they can draw power from their vehicles? ie drive up on rollers and put the vehicle in gear (just like when they test brakes), thus avoiding big electric motors. Or putting a pulley system on the front of their engines to draw power?
That's how they did it 100 years ago using a Ford Model T. Common practice for poor man mining. Thanks for sharing your idea !
@@allansgoldmining being a "poor" man myself, ideas come all the time :) Here in Denmark we can try and find amber, that is about the limit. However the dream is to go to Australia on a holiday and do some prospecting when I go on my pension.
That's the truth. I think more ideas and inventions come from poor prospectors. Me included. Lol !! Best of luck to you on retirement and the Aussie adventure. Sounds fun !
On a side note, I maybe in Denmark late June to quarantine before leaving to Greenland on a gold prospecting expedition.
@@allansgoldmining I have heard that Greenland can be promissing. We live in Assens on the island of Fyn (funen). Give me a call at shieldfoder@gmail.com, maybe we can find some fun things to do if you have the time.
Thanks might do that. We'll see how the schedule unfolds.
i know you know Richard and grey over on the old 4 witches clam they renamed it now. one of thees winter i will be back i like the screen on it that cool now doing the green gold out hear in Colorado but living on a old hydrollick mine my spelling suck i do have a creek but it a desert up hear very dry on prospectors radio a new high-banker i was in ridge-crest on a Sunday and i won a gold hog so peace out
How long do you have to pan like this to make your money back on what you spent on gear and fuel?
Hi Delicious. Would be a very long time. Lean pickins out here. Ha ha ! Virgin ground runs about $25/yd. If I work hard, can run about 2 yards/day by hand with the wash plant. Helps pay for gas and food, but that's about it. Would need heavy equipment to move volume to make it worth it. That's why I haven't quit my day job. Just enjoying the adventure. Consider it like fishing. Spending big $$$ on boat and tackle to catch a $10 fish. LOL !
@@allansgoldmining I've always despised and disdained fishing too.
@@allansgoldmining Still, if I could get 25$ per yard running my track loader, if there was enough land to filter through, I could make about 1000$ per day, as it only takes me about 2 minutes to scoop up a yard of dirt and rock, and a moderate 8 hour day is 480 minutes long, enough time to scoop up 240 yards [assuming one has a conveyor belt and it is all set up on a long lasting tank of diesel from an efficient little diesel engine] because 240 yards would be about 6000$ but by the time you counted fuel, travel, overhead of all possible kinds [more if you stay elsewhere in a hotel and not in a camper or tent on site], you might make 1000$ per day... Maybe.
@@DeliciousDeBlair yeah, that's the dilemma. Not enough volume out here at that grade. Plus the permitting and legal fees would out weigh the benefit... Plus the Greenies would go crazy if I ran over a cactus. Ugh !! So I have to remain stealthy. Lol !!
why do you use the smooth part of the pan when cleaning up what are the riffles for.
If you look a little closer, you will notice my pan has two types of riffles, coarse on one side and fine on the other. The coarse is used for stratification and cutting coarse material. The fine riffles are used for fine material.
Yes i saw that exelent pan i thought you were working inbetween them if you were not please accept my appolagy thank you good videos
I think your RUclips likes will make more money then that tiny Gold :)
Ha ha ! So true. But I'm not in it for the $$. Just having fun. Sort of like fishing. You never know what you'll catch in that sluice box ! Actually, that was only a test of four 5 gallon buckets. Placer production is measured by value per cubic yard. My virgin ground runs $60/cu.yd. That's very profitable at volume. Thanks !
I have a homemade dry washer..I don't lose any gold..I don't see any reason to try your modification..it looks like you have too much air pressure blowing through your small dry washer and the upper hopper is at such a steep angle everything is falling off...what brand is the dry washer you're using??
Bring me your tailings. I will be more than happy to debunk your claim that your dry washer doesn't lose gold. You need to understand the physics behind this process. The material I am working with contains high quantities of clay and silt. Therefore, the excessive dust is not from increased blower volume. The angle of the riffle board is set at 2:1, which is very shallow compare to most operations.
Pretty nifty
What if you drywasher just sucks? Keene makes a good model.
Thanks Wade. Same principles and physics apply regardless of manufacturer. Indeed, Keene makes really good equipment.
I got that same pan, except I don't catch any gold...yet.
Hi Mitchell. Keep trying. I find it works well, however, I use a Blue Bowl to recover my cons. I use the pan merely to see if I got anything. BTW, recently found a new pan sold by Snake River Products called a Maverick Pan. Works so good I bought two ! Good luck prospecting !
Allan Guthmiller - I'm living mobile. Just bought a small pebble crusher yesterday. Ready to get smashing & panning.
Thanks for sharing your ideas. Find a big one. 💰🏅
👍👍👍
Your original problem statement sounds like your air flow may be too high to begin with, if you're losing gold over the riffles all the way down just a thought.
Thanks for thoughts Ed. I've significant testing regarding air flow, slope and riffle dimension. It's purely a physics issue. I have a significant amount of clay and silt in the material, lending an appearance of excessive air volume in the video. If I run it any lower, the riffles would become clogged.
@@allansgoldmining Understood. Did the added metal mesh affect the static charge at all?
I'm not sure. Haven't performed any tests on that. My best guess would be no change. Using an additional layer of nylon material, as an alternative, might increase the effect. Worth looking into.
All that then panning too......
Not for me...slow....machine
must do panning or it.'ll take forever.
Just metal detect your damn tailings and save yourself a nugget
I do that too.
Why Alan why do you dress like you do why no one in the world does so are you thinking that old timers dressed that way well they didnt your dressed like a television fake gold miner dressed not at all like a miner not a TINY BIT
Obviously you know nothing.
