Thanks for the interested comments, After doing more tests it's important to place any row of magnets in opposite polarity to each other. This prevents the magnetic particles from repelling each other as they are attracted to the magnets. This method also allows for the field to be dispersed to slow the gold acceleration through the sluice box and still collect the non-gold magnetic particles before they get to the sluice box. Don't throw out the gathered magnetic materials as gold can be stuck to it. Keep it for later processing.
No one has thought of it because they have actually ran a sluice or panned and have ran across black sand, a product that is ALWAYS present with placer gold and is highly magnetic!
I think all the elements of Ken's work with magnets is very interesting, and anything that can be used to recover the finer values in a river system holds the most promise going forward. One other element I find particularly interesting is what I might call 'Invisible' gold. Gold so fine that it is nearly invisible to the naked eye. We've all 'seen' it in the right conditions, a tiny sparkle at the trailing edge of the Black Sands that produces a glint as it tumbles in our pans and then disappears until it again catches a ray of sunshine for just an instant. What most of us have failed to realize is just how much of this gold is failing to get trapped in our riffles in those rivers that normally carry values so fine that they are difficult to recover themselves, much less the ultra fines we never see, or realize may even exceed in volume those fines we do see. My own Snake river is one I expect to loaded with just such fines. I had hoped to follow thru on some preliminary tests I did last year, but health issues prevented me. This year looks as tho I'll be diving into that program at full throttle, and hope to report the results when we have ice-out this Spring. See ya then!
I wonder what a significant amount, say a half gram, of this nano gold would look like, and how to handle it. Melting it in a kiln seems the only way, a torch would just blow it away, but just identifying and collecting it seems daunting.
Notice the gold coin was stopped or slowed at the EDGES of the magnet, but sailed through the middle. This is very important and was first brought to my attention by Theora Apophasis (credit where it's due).
install a bar magnet ABOVE the water across the sluice at any adjustable height.. it willl pick up alot of the magnetics.. several would seem to be even better.. and then magnets under the sluice box will slow the gold.. just a thought.. maybe a rotating upper magnet or even electromagnet to turn and depolarize anddrop off the magnetics into another bucket for further inspection
You should try a alternating rows of magnets on drum that spins at a high rate of speed opposite to the water flow. The faster changing magnetic fields will induce much larger eddy currents inside gold particles, thus slow them down much more than the slow speed of water alone. One concern is that small particles have smaller eddy currents for same change in magnetic fields. Bulk iron like a nail work great for an electromagnet but have high eddy current losses if you alternate the magnetic field rapidly. Transformer use insulated laminations with a poor conducting steel to reduce eddy currents. Magnetite, nano particles suspended in epoxy make a great composite magnetic core for a high frequency coil with almost no eddy current losses. And so, even if it is that small gold particles have less internal eddy currents to slow them down as they approach a magnet, if the magnets were spinning on a rotor at a high rate of speed, means the gold would slow down much much faster.
Hey Keith, These are very very good ideas. I was going to test a new design using a smaller inner core on my gold magnet (see my other video, 'make a gold magnet'). The idea is to use a sync generator and much smaller coils to create better back emf to attract gold. I like your idea on using epoxy and will try that. Also using a reverse drum to increase the eddie current is excellent. Good call. Ken
KenKlondike, things to consider: 1) Permeability is proportionate to packing density. 2) increased packing density increases chances of eddy currents. 3) Smaller synthesized nano magnetite particles have lower coercivity translating into lower hystorises losses. I am not certain, but I believe that if you want to save energy, a freewheeling spinning drum with alternating rows of permanent magnets might be better then alternating magnetic fields in stationary field coils. And if you want to make a drum with rows of alternating electro magnets fed power with two slip rings, then you will be better off with hard iron verses magnetite because your not flipping the magnetic domains. Either way of making a drum, you want many poles. 200 poles on a drum spinning at 3600 rpms (60 revolutions per second) and powered by any cheap induction motor, alternates the magnetic fields (from a stationary observer) near the edge of the drum 72,000 times a second. You'll want only plastic parts to get close the the drum.
understood. The idea is to increase the varying magnetic field as much as possible. As Faraday taught us, only a varying magnetic field will produce eddie currents and electricity. In other words, more motion is better. But I have other ideas in mind as well, please see my video on making a gold magnet. Its an electromagnet that attracts gold. I would like your input on that if you have the time. Warm regards, kk
Hi you two, I hope you'll come back to read this because you've given me an idea. Suppose you have a bunch of those potent 40mm bar magnets and attached (wove, JB Welded, wrapped) them across at the middle to to several (6-8) thin axles that reach from side to side all being driven by a pulley or chain system on the outside rotating at high speed just above the waters flow, forcing the nano gold to the bottom in stages. altering the poles Then at the end of the sluice you had a .5mm slit in sheet metal that looked like this: _______------ \ that 'siphoned' that layer of water into a holding bin to settle for a few days? I know I'm not in your league, yet, and appreciate the direction your guiding me in. I would even take a snicker or loud GUFFAW as positive criticism. I guess balancing them would be impossible :( It would also probably create a portal and demons would get through...
@@imdawolfman2698 a chain saw would probably be more power than needed. a rotating drum should freewheel for the most part. just overcome the friction of the bearings. a small electric motor should be more than sufficient. one can put magnets on an axle but I proposed a drum because at a larger radius they travel faster for each rpm. maybe JB weld will do fine. and yes balancing will be important.
Ken, Very interesting about the magnet and gold coin. I think all the research going into gold and magnets in recovery systems is closing in on very important ground. Sure, we all want the heavy stuff, but micro fines is going to leave an ever larger footprint in the game going forward. That gold coin stopping/slowing is an epiphany . Was that a common, or rare earth magnet you were using? The information about 'The Magnetic Zone' to clear riffles of black sands was confirmed as I said, but is only info on that particular aspect and not necessarily a specific "how To" sluice system. What you have shown here about a magnetic field slowing down the migration of gold across the riffles (as I suspect your demonstration implies), seems to be the icing on the cake. If gold moves to and then under a magnetic field designed to reduce the weight of the black sands so those can clear out in a significantly reduced water flow, and yet super fine gold be stopped even sooner by that same magnetic field, a man might make pumping common gravels pay off more significantly while after the 'Big One' I live within 200 yards of a large river documented to carry huge amounts of fines the old timers simply could not recover in significant amounts with common rockers and burlap a hundred and thirty years ago. But some did take as much as 1- 2.5 troy ounces a day processing only .2 yards of gravel a day. The price of gold then being $20 per troy ounce. The ultra, ultra fines here are so spread thru the general gravels, I can hardly wait to see what may be had in a finely tuned sluice. The visible fines in pay streaks might well turn into bonanzas if we ever get to trap all that goes thru our systems we once thought might catch them. I suspect far more is lost in systems designed to wash out the Black sands by force of flow those need, and with them the powder gold no bigger than grains of flour you might bake bread with. Certainly those we need magnifying glasses to see. Gimme a sack full of that we've been pumping out the end of our sluices, and you might just see a new gold rush!
Hi ken, can you tell me why you are using a ferrite magnet verses using a neodymuim magnet for this process? Are the magnetic properties differant in some way?
+KenKlondike I have ordered a bunch of neodymuim magnets of all shapes and sizes to do some experiments with. I have an infinite source of micron gold in the 25um range and am trying to develop a system that will separate the micro gold from the silicates and magnetite and concentrate the fine gold to process without using chemicals. Have you had any luck with magnets for the supper fine stuff?? Water gravity systems at these size ranges do not work well as the micro gold has no weight compared to the other materiel in the mix and just moves along with everything else.
+Rob Rainbow I know what you mean, I have prospected this and it takes a very fine pan motion and patience to separate it. Step 1: I would suggest a long wash board with mounds on it (like a kids slide - what we used to call a bumpy slide) Material flowing down would encounter the rolls and be heaved up where a magnet on top would catch the magnetic materials. Step 2: Take the materials that were filtered and screen it with a screen jig. Step 3: Take whats screened and run it through a fine sluice.
+Rob Rainbow I saw an article on a guy in the Yukon and he made a small trommel. It looked like a cement mixer but he put heavy steel rods in it. The material was added and the rods flattened the micro gold out. As you know gold can be flattened to extremely thin particles. The flattened gold was then easily panned. When the gold is thin you may also be able to work the magnetic fields in a way to cause them to float on a slurry.
Now tuen the magnet onto its corner. Then make a bunch of magnets with the corners on edge. Put the corners to your track. Works much better than just the magnet on the flat.
So, do you know who Ken Wheeler is before I stick my foot in my mouth? Love the idea/concept. As I understand, low permeability repels magnets, creating movement (or diamagnetic breaking) as a result if you plan it out correctly. What is that, centrifugal divergence or something when it is repelled, coupled with an Eddy Current. What the hell do I know though? I didn't even go to high school, much. Ask Ken. He knows.
A year or so ago I downloaded about 8 videos related to this one that showed the building of a sluice using magnets to trap magnatite and push gold down and now they are private ... WHY???
KenKlondike, why not just have a small thin barrier of say rubber or some other non magnetic martial that conveyors around the magnets so with a collection bin underneath the drop off point... the magnetic materials will be "pinned" to the martial when it is near the magnets and as the conveyor moves the material off the sluce and out of the magnetic field it will then fall off down into a collection bin.
Hey Grackis Godwind, Thanks for the post. This is a very good idea. The mini conveyor would need a method to turn the small drums. Electricity, water flow, solar, or a belt off the trommel? What do you have in mind? kk
Rather, gold itself is non magnetic, but a changing magnetic field induces currents (called eddy currents), in conductive materials, think coils on a generator. But, those currents do not go through a wire to do work, but circulate inside the material and internal resistance converts it to heat. All electrical currents including eddy cure ts create their own magnetic fields, but because of lenz's law they are in opposition to the external changing magnetic fields that created them. This is why magnets will always float above a super conducting material. The induced currents and opposing magnetic fields inside the gold particles is that causes the gold to slow down as any relative motion to a magnetic it is being opposed. Although, I'm not sure if small gold flecks generate enough eddy currents to be noticeable. But it will certainly slow a large gold coin passing a magnet or a magnet passing falling through a copper pipe and sliding down an aluminum bar.
@@johnnyllooddte3415: 'but yes it takes another metal between the magnet and gold'. I have never heard of this and seen it not be true. If you float gold on styrofoam (or a tiny boat) you can push it around with a magnetic field, and I have tied a string to the top of a vertical bar magnet with a button of gold at the other end, it will nearly come to a stop in front of the magnet when allowed to fall like a pendulum.
Pure gold is diamagnetic. A great test is get a piece of styrofoam and put it in a bowl of water. Put a nugget on that foam and bring a magnet close to it. The piece of gold will push away from the magnet. The concept still works though. The agitation in your water will help keep you heavy metals from grabbing your gold as the magnet both pulls the heavy elements out and pushes your gold into your matting. I would love to see some more vids about you using your setup though. Great stuff that you see nobody using.
Bullshit! Blacksand will be attracted to the magnets and you lose all of your gold in the process or you waste more time cleaning out black sand than dredging or sluicing!
You run the magnets above the sluice. It will pull the magnetic black sand out and slow the gold in the sluice, pushing it into the rifles. There are ways to set it up so you can easily clean the black sand periodically from the magnets to keep from diminishing results. Maybe you should try experimenting with it on your cons in a closed system, if your so worried about time in the field. Or you can just continue being a troll, and calling bullshit on something you have 0 experience with.
Most things are diamagnetic. Gold is no exception, but the diamagnetic effect is too small to be useful. Rather, this video demonstrates a much larger effect called the lenz effect, by a changing external magnetic field inducing currents (called eddy currents) inside a conductor like a gold coin, but said currents create their own magnetic fields that oppose the change in the external magnetic field.
So what would happen if you take a rail gun setup, but instead of aligning the magnetism to face the same way, set the last induced magnetic field in reverse, to sort of supplement diamagneticism such that it would become paramagnetic to gold?
Frank Scramlin, no paramagnetisim with gold.rather than magnetism arising from atoms or molecules and their electrons' spin the magnetisim seen here is due to lenz's law. Induced currents are always repulsive to the magnets that created them. Further point evidence of this is that it requires a change in the applied magnetic field to induce currents in the gold, that in turn induces temporary magnetic fields that go away if the external magnetic fields does not continue to change. In other words, there is no magnetism in gold in a static magnetic field. The difference between the gold and silver were only due to the height of the silver coin made it less vertically stable on approach to the magnet, additional size also allowed larger eddy currents and more back emf.
I would think that the sluice would be jammed constantly with black sand, doesn't look practical at all. And what is the point? Gold will be in the ripples or matting or miners moss no matter what anyway...
I would think gold would be slightly repelled by magnet and opposite for ferrous materials sting field above ripples should in theory push gold into ripples assisting gravity and pull up the ferrous materials and the rocks and organic materials should slide through the system
the gold coin is suppose to be the finest available, 99.999 pure gold for the Canadian mint. The magnetic field causes eddies in the coin which in turn is effected by the magnets field.
Hi Chuck, thanks for the comment. The gold coin is not plated. Any conductive material will work, however as mentioned in the video, size matters. I don't have a nugget larger than the washer, but as soon as I find one will.
Gold is not magnetic why would a magnet slow it down. Unless the coin was not pure gold. The magnet may reduce the black magnetic sands but not them all its still up to the mats but I suppose its doing something. Saving a little time maybe.
Thanks for the note PC, True - gold is not magnetic but it can be magnetized. Here is another video I did on how to make a gold magnet th-cam.com/video/-9e7DBzdpQY/w-d-xo.html
Thanks for the comment Carl. To be clear the gold I used is 0.99999 pure gold. Any conductive, but not magnetic, material will have the same effect. ie: silver and aluminum show the same effect. Electricity is not a thing, it is a result of movement. The principle shown in the video is caused by movement which creates an apposing magnetic field.
the Lenz effect magnetic Eddie currents. A magnet's field effects other metals that pass by. This induces a counter magnetic field in the other metal. Its the same principal used by Faraday to discovered that electricity has (is) a magnetic field.
Hey Christian, Thanks for the comment. No - the method pulls the black sands out before it hits the riffles. Have a look at my other video - make a gold magnet and you will see the principle of how it works. Take care
You have it all wrong. The magnets are suspended above the water flow, pulling the magnetite and iron out of the stream sparing the riffles, meanwhile slowing the gold so it drops into them.
Друзья! не могли бы вы сказать мне, кто уже сделал этот опыт? У него в руках алюминий и магнит. Что он сделал с магнитом? Кен говорит, что знаниями нужно делиться, но он молчит и не дает ни одного определяющего ответа. Хотя он сам четыре года назад попросил дать точное описание конструкции электрических и магнитов вот сдесь th-cam.com/video/HsC7Q0kwnGY/w-d-xo.html
Hahahahaha that’s not what happens! Copper is diamagnetic, what happens is the magnet causes eddy currents. Copper, gold, aluminium are all diamagnetic.
Correct, but gold is Diamagnetic . An applied magnetic field to gold creates an induced magnetic field in the opposite direction,hence the gold is repelled as it moves past a fixed magnet.The first magnet above the path is simply to attract ferrous metals and let gold continue down the path,the second magnet is a "breaking magnet" which "slows" the gold down to a relatively slower speed than the water and hence the gold is caught in the troughs as it slows down.If the riffles were not there the gold would simply speed up again to the speed of the water and be lost.
Thanks for the interested comments,
After doing more tests it's important to place any row of magnets in opposite polarity to each other. This prevents the magnetic particles from repelling each other as they are attracted to the magnets. This method also allows for the field to be dispersed to slow the gold acceleration through the sluice box and still collect the non-gold magnetic particles before they get to the sluice box.
Don't throw out the gathered magnetic materials as gold can be stuck to it. Keep it for later processing.
Do yourself a favor and add an electromagnet. It works better

Thats a good observation. It does clog up. I am working on a small conveyor type system to keep the first magnet bank clean.

And the reason is?
so you're saying that a ferrous magnet + aluminium can attreact gold while neither alone will?
Rather, gold itself is non magnetic, but a changing magnetic field induces currents (called eddy currents), in conductive materials, think coils on a generator. But, those currents do not go through a wire to do work, but circulate inside the material and internal resistance converts it to heat.

it doesnt have to be aluminium,, but yes it takes another metal between the magnet and gold

If you float gold on styrofoam (or a tiny boat) you can push it around with a magnetic field, and I have tied a string to the top of a vertical bar magnet with a button of gold at the other end, it will nearly come to a stop in front of the magnet when allowed to fall like a pendulum.

Bullshit! Blacksand will be attracted to the magnets and you lose all of your gold in the process or you waste more time cleaning out black sand than dredging or sluicing!
You run the magnets above the sluice. It will pull the magnetic black sand out and slow the gold in the sluice, pushing it into the rifles. There are ways to set it up so you can easily clean the black sand periodically from the magnets to keep from diminishing results. Maybe you should try experimenting with it on your cons in a closed system, if your so worried about time in the field. Or you can just continue being a troll, and calling bullshit on something you have 0 experience with.
Most things are diamagnetic. Gold is no exception, but the diamagnetic effect is too small to be useful. Rather, this video demonstrates a much larger effect called the lenz effect, by a changing external magnetic field inducing currents (called eddy currents) inside a conductor like a gold coin, but said currents create their own magnetic fields that oppose the change in the external magnetic field.
So what would happen if you take a rail gun setup, but instead of aligning the magnetism to face the same way, set the last induced magnetic field in reverse, to sort of supplement diamagneticism such that it would become paramagnetic to gold?
Frank Scramlin, no paramagnetisim with gold.rather than magnetism arising from atoms or molecules and their electrons' spin the magnetisim seen here is due to lenz's law. Induced currents are always repulsive to the magnets that created them. Further point evidence of this is that it requires a change in the applied magnetic field to induce currents in the gold, that in turn induces temporary magnetic fields that go away if the external magnetic fields does not continue to change. In other words, there is no magnetism in gold in a static magnetic field. The difference between the gold and silver were only due to the height of the silver coin made it less vertically stable on approach to the magnet, additional size also allowed larger eddy currents and more back emf.
I would think that the sluice would be jammed constantly with black sand, doesn't look practical at all. And what is the point? Gold will be in the ripples or matting or miners moss no matter what anyway...
over 50% of all gold is washed away.. thats why
That's badass I love science in prospecting :)
I would think gold would be slightly repelled by magnet and opposite for ferrous materials sting field above ripples should in theory push gold into ripples assisting gravity and pull up the ferrous materials and the rocks and organic materials should slide through the system
learned something new...great vid...that magnetic concept must have a slew of other applications..mickeyminer
great video thx
the thicker wall of the copper pipe the slower the magnet will be.
Good luck. Dont let the nuggets get away !
thanks Giulio
A Neodymium magnet is much better and will float very slow down the pipe without even toughing the sides.
Hey Gord, A smart comment, thanks
Is not the coin got infuriates in it which is why it's slowing down with the magnets
the gold coin is suppose to be the finest available, 99.999 pure gold for the Canadian mint. The magnetic field causes eddies in the coin which in turn is effected by the magnets field.
The gold coin is plated. Use a nugget.
Hi Chuck, thanks for the comment. The gold coin is not plated. Any conductive material will work, however as mentioned in the video, size matters.
I don't have a nugget larger than the washer, but as soon as I find one will.
actually its dielectric deceleration that causes that to happen (pathetically called lens law, but thats merely a BS description, not an explanation)
im glad you spotted that typo, youre so smart.
Theoria Apophasis Doesn't you hate it when peepull do dat stuf... lol.. I no i does
Thanks for caring for grammar. Did you agree with the content of the reply?
respect please
KenKlondike are there any plexiglass gold pans out there for sale?
Gold is not magnetic why would a magnet slow it down. Unless the coin was not pure gold. The magnet may reduce the black magnetic sands but not them all its still up to the mats but I suppose its doing something. Saving a little time maybe.
Thanks for the note PC, True - gold is not magnetic but it can be magnetized. Here is another video I did on how to make a gold magnet
th-cam.com/video/-9e7DBzdpQY/w-d-xo.html
just to let all the smart people know gold has some iron in raw form not much but enough for a magnet to effect travel
Thanks for the comment Carl. To be clear the gold I used is 0.99999 pure gold. Any conductive, but not magnetic, material will have the same effect. ie: silver and aluminum show the same effect.
Electricity is not a thing, it is a result of movement. The principle shown in the video is caused by movement which creates an apposing magnetic field.
cool
Хмм это и есть вы! круто!!!
Спасибо, мой друг
What sort of principle causes the general principal to work?
the Lenz effect magnetic Eddie currents.
A magnet's field effects other metals that pass by. This induces a counter magnetic field in the other metal. Its the same principal used by Faraday to discovered that electricity has (is) a magnetic field.
Fill up the rifles with black sand so all your gold go back to the stream that’s brilliant !!!!!!! 🤟🏾
Hey Christian, Thanks for the comment. No - the method pulls the black sands out before it hits the riffles. Have a look at my other video - make a gold magnet and you will see the principle of how it works. Take care
You have it all wrong. The magnets are suspended above the water flow, pulling the magnetite and iron out of the stream sparing the riffles, meanwhile slowing the gold so it drops into them.
Друзья! не могли бы вы сказать мне, кто уже сделал этот опыт? У него в руках алюминий и магнит. Что он сделал с магнитом? Кен говорит, что знаниями нужно делиться, но он молчит и не дает ни одного определяющего ответа. Хотя он сам четыре года назад попросил дать точное описание конструкции электрических и магнитов вот сдесь th-cam.com/video/HsC7Q0kwnGY/w-d-xo.html

perhaps
100 percent gold,, 100. really
100% of 86%
Only if you are dropping gold coins in.....
🖒🖒🖒🖒🖒🖒🖒🖒🖒🖒
not pure gold till has magnetite in it
The coin is gold of course. I'll be doing another video on this subject to show the system in action.
Hahahahaha that’s not what happens! Copper is diamagnetic, what happens is the magnet causes eddy currents. Copper, gold, aluminium are all diamagnetic.
Gold is not magnetic
Correct, but gold is Diamagnetic . An applied magnetic field to gold creates an induced magnetic field in the opposite direction,hence the gold is repelled as it moves past a fixed magnet.The first magnet above the path is simply to attract ferrous metals and let gold continue down the path,the second magnet is a "breaking magnet" which "slows" the gold down to a relatively slower speed than the water and hence the gold is caught in the troughs as it slows down.If the riffles were not there the gold would simply speed up again to the speed of the water and be lost.
This is known as Lenz's law., PLEASE LEARN BASIC SPELLING ! PRINCIPLE NOT PRINCIPAL!!!
oh oh, the spelling police. Also in charge of grammar I would expect.
Thanks for the comments Tony, next time we will be more careful.
The Grammar Nazi has spoken.
