Non-Chemical Anyone ever recovered gold using sound waves?

[jsargent]

Sometimes, in scrap yards, you can find old stainless steel vapor degreaser tanks that were used for freon before it was banned. In many of them, there is a powerful ultrasonic unit in the bottom. You can spot them by looking for a cooling coil mounted around the inside near the top of the tank. Most that I've seen were about 18" x 30" x 30" deep. The u'sonic power unit is usually a heavy separate box with a cable.

When freon was first banned, you could find tons of them, especially in scrap yards that were near large electronics manufacturers (i.e., Silicon Valley). In the last few years, I have still run across a few of them. I found one in Houston a couple of years ago.

Thanks for the tip. Time for a road trip to Green Guys Recycling and another great excuse to bring home a fresh pile of junk.

I would deffinitely not reccomend putting a CPU in some HCL acid in the microwave and powering it up. However, it could be done, harmlessly in a vaccuum. The presence of oxygen is what makes the cool sparks that occur when metal is used in a microwave.

A really cool company has patented a process for using high frequency microwaves in a vaccum to refine old tires into their organic bases, such as oil, gasoline, and other petrols. The steel from the belts inside the tires is also seperated and recycled.

The company stock Ticker is GBRC, Global Resource Corp. Don't know if this helps you, or intrigues you however I figured it could be worth the read?

Anybody ever used Supercritical co2 to extract gold from an ar soulution?

No... but funny you should mention it. Earlier today I was thinking about supercritical CO2 as a potential leaching agent. 15 years ago I worked with a bench top supercritical CO2 extractor at the lab. Used it to extract organics from soil samples. Pretty cool technology and totally benign. I wonder if it might be a useful alternative to DMG? The cool thing is that no precipitation is needed after extraction. Just open the valve and the CO2 gasses off and all that's left is the extracted material.

Jeff, I checked out your web site.

From what i can gather your looking for new processes in recovery and refining. I like your train of thought. :wink: :wink:

I also like the fact your using real science and not some pie in the sky dream. I'd like to pick your brain sometime.

Thanks

Hey Thanks Aflac! Drop me an email or call anytime. I really appreciate the video links and other info and links you've posted here. This forum is GREAT :!: Many knowledgeable and helpful folks here.

Tommy Joe and others:

You might look into the works of F.G. Cottrell ( around the turn of the century ) and A.D. Moore in regards to using electrostatics for precipitation. These processes are being used in industry today. I'm currently building an electrostataic generator with a drum pickup/discharge that I gleaned from Moores' book. A lot of possibilities there.

Also, as I posted a couple years back, is the bulding and using of a non-ferrous magnet. I built one and it did move small particles about fifteen inches or so. But being of an AC source, the amps can be quite lethal.

Another forum member posted a treatise he picked up, but there is nothing like building one and seeing what can be done.

Have fun, domo, Phill

My earlier post is labled "Non-ferrous magnetism"

Evo, Take a look at this. :arrow: http://goldrefiningforum.com/phpBB3/download/file.php?id=2987

Tommy Joe: Surfing and caught your post about sound waves. Have you ever thought about electrostatics ? It is being done in a grand commecial way. I am building a small unit based on Cottrells work ( c. 1900's ) Also look up the work of Walt Noon. And you might check out WWW.LINDSAYBKS.COM . Wealth of information there. Phill

We had a huge one, bigger than a bathtub at one place I worked. That cooling coil worked well to condense the freon vapor, but apparently not well enough.

Fill it part way with water and set your jugs of leach in the tank.

What ? No pickup on electrostatics !! Makes the world go round . Impossible to live without the transfer of those little buggers . There is a photo of a Van de Graff generator built back in the thirties floating around. I was lucky enough to be on the labor end of one built at my university about fifty years back. Now that REALLY had a spark gap. You really have to experience it to believe what power can be achieved with E/S. Phill

Isn't anyone out there on this forum interested in E/S for Au revovery ? Sure would like to hear from you !

I see you are an engineer. Probably not in your line, but grabbing at straws is the way I usually learn. Have you ever experimented in or built anything in regards to electrostatics ? Phill

 

[butcher]

I work as a building engineer in a hospital, running and repairing boilers chillers and and all the equiptment to run the building, make repair's to almost everything in the hospital, am boilerman,steamfitter, plumber, electrician, do electronics, repairs to firepanels, repair most anything and everything,
I know almost nothing about the use of electrostatics or sound wave's as you fellers are discussing their use.

since I am here, I have noticed, something you guys might answer for me, I have noticed when a precipitant forms and it forms crystals, they predominately form on one side of all my jars, always seem to form crystals on that side more and if they form on side of jar always on that side, for where I am at it is the southern side,it may shift somewhat east or west but always on south, since I am in the northern hemisphere the sun and moon is always southerly, would these effect crystalization? or could it be light or temperature, as even if jar is turned it still forms southerly, maybe there just good ole dixie land crystals? or is there a principle I am missing?

Butcher:

Gosh, I am repeating myself. You answered a post of mine sometimes back in regards to the same question. Pardon my blooper. As to your question about material seeking one side of a container over the other side, I have no answer to that one. However, I will be following this as I am most interested in what others have to offer. Any astrologers out there ? Phill

Butcher:

I would think it depends on slight temperature variations in your vessels. Solubility for salts is generally higher with higher temperature. So if you have a heat source, for example the sun, then it would make crystallization start in the back side of the vessel where the temperature is colder. When crystallization have started at one place it is easier to grow there than start new crystals so the effect will be amplified.

If you have a solution that is allowed to evaporate very slowly then large crystals will form as the energy in a large crystal is lower than in a small crystal. No, it's not a new age thing, it is sound science. The atoms making up the edge and corners of a crystal is more loosely attached than the ones on the flat crystal face, therefore a large crystal is slightly harder to dissolve than a small crystal. The effect is most easily shown when you have a closed jar with small crystals in a solution. Over time the larger crystals will grow and the smaller shrink. Small temperature variations will speed things up but even at constant temperature this is an ongoing process.

thanks, I do need more study on crystal formation, well I am kinda disappointed, I thought these may have been southerly seeking crystals. :lol:
