Jason, I think your laugh when weighing the single tiny bead told the whole story, you may as well be gold panning in the Los Angeles River. Thanks for the demo and the detailed explanation.
The red colour was produced by the presence of Antimony (Sb). I've seen that in the slag from gold pours in mines where antimony occurred within the ore as stibnite. Stibnite in a floatation circuit will suppress other (perhaps gold-bearing) sulphides, so your chemistry has to be just right to avoid losing those to tails.
@@Dgafsranger The much better way is to use mercury to just soak the whole batch into it for a while until it strips all the gold plating from these!Than either evaporate/boil all the mercury or dissolve it in nitric acid and that's it!
Good video! What we can take from this is that it's not feasible to go after that little amount of AU. I think I would have tested with a magnet and jeweler acid scratch test b4 firing up the furnace.
8:17 The bubbles could be zinc evaporating... not sure what kind of low melting alloy they used but zinc is often a component of that kind of alloy. Saw the XRF... could be Antimony, it boils at 1500 C.
pretty amazing how thin gold plating can be ...one ounce of gold can cover an area of 950 square feet so if you get enough gold rings to cover 950 square feet you'll be in the money brother...awesome vids Jason
Bead Purity: Simply, why did you not XRF the bead? Not knowing how many pounds of rings there is nickel and copper have value. My thought is to reverse electro plate removing the gold surface then the nickel and copper. Once the lab is set up electricity does the work.
Yes gold oxide makes red glass but that might be lead crystal that I've seen and I've seen Italian army desert service goggles from the 30s with purple red glass that's said to be coloured with gold.
It looks like they took an antimony-hardened lead alloy to make it relatively dense and hard enough to wear without deforming, covered it with a bronze alloy, and then flash-plated it with like a micron of gold. Definitely just a little too much lead to meet regulations, haha!
I don't remember if you had a video on de-plating using sulfuric acid as the electrolyte, but I think it would have been faster and cheaper to do it that way. The electrolyte is reusable.
8:00 The bubbles could be boiling borax as it's boiling temp is 2867 F and something may have lowered it's boiling point in the melt a bit if it isn't that hot.
Gold went into the red glass as in the early days red glass was rare & those rings are from Lord of the rings Movie, You should XRF the Red Glass Slag & it might have your missing Gold
I was gonna say the exact same thing. My friend does glass blowing and when a gold bead is held in the flame in front of the hot glass the gold fumes off and sticks to the glass. Gold fume gives the glass a red/pink colour. He makes flower implosions and pipes. Silver fume is a smokey clear blue/green/white/yellow.
I think you are correct, he should clean cut one of the rings in half to determine the plating thickness. It is much lower than vermeille , I would just grind up the whole lot and Aqua Regia it ...then sulfuric acid precipitate out the lead.
That’s what I was thinking too. Lots of reds in silicate glasses are from gold ions. The plating could have a tin base and in the crucible that could reduce it and make the gold go into the slag.
@@rrfields65 I agree with your proposal - hydrometallurgy is much more efficient. he very stupidly rests against one of his own method of stove, everything goes into it, and electronic garbage and jewelry ... very stupid ...
I think your rings are coated with an alloy called Nordic Gold, which contains no gold, but does have some tin which could account for the Sn in your XRF analysis.
Great video! @sreetips on his channel pretty much confirmed what you're saying here - he has a few videos on recovering gold chemically (and I think electrically) from gold plated material and the reality (which surprised me) is that the gold plate layer is extremely thin and you end up processing a lot of material to yield a small amount of gold. I also think that however you attempt to do this it ends up requiring a ton of time and materials. It's really counter intuitive because it looks so shiny - but I guess it's true what they say about "all that glitters" and all that ;)
@@mbmmllc Yep. Look up the definitions of the various gold plated classes here in the US. We are looking at millionths of an inch (e.g. a few microns thickness). The bubbling may well have been lead boiling. Did the temp get about about 1740 deg C? When you did the cupel test, there was no need for the bismuth. All that lead in the rings will gather the oxides and suck them into the cupel. Also, your electric furnace must be quite leaky. Normally during an assay, the door is left open somewhat so oxygen can get in to oxidize the base metals faster and more completely.
Where did you get the little Electric furnace and how hot does it get will it get to 2100 F? If so could you please share a link because it's the perfect size for me?
About those bubless, many speculations are that they are caused by boiling metals but i found few comments that seems more logical to me, that it could be boiling borax (1,575 °C; 2,867 °F; 1,848 K). If your furnance got that hot it might cause it to evaporate. I will go with that theory because the metal on the bottom seems quite still (on the other hand the liquid borax looks very "mad and bubly")
Best way I think would be sulfuric cell but man theres definitely not much on those eh. Thanks from Ontario Canada. Also was wondering if you seen my message about the ic chips. I have about 150 kilo of very high grade and prob 500 pounds of low grade.
@@mbmmllc ok thanks anyways. Yeah with the gold corned bga chips yielding anywhere from 5 to 10 grams per kilo of caps I really wanna do the process because places like board sort pay well for lots of items but not the high yeild stuff. I figure theres about 250 to 500 gram of gold total in all my chips. Maybe in the near future I will buy a table. Thanks and keep up the great vids
Try using 5 parts HCL to one part Nitric Acid and see if you can get the gold in solution. I’m sure you have done it before but it works really well for gold plated and gold filled items and if that is silver in there the the silver will separate from the gold and you simply filter it out then drop the gold out of solution and you end up with a gold powder when it’s dried that u can melt If there is 200 rings there you should recover 6 grams .03 x 200= 6 right ? Seems like it’s to much lol
It isn't that simple. The HCl reacts with the surface of the silver and any tin present - passivating them and preventing them from being dissolved. That is why nitric acid boils are used until silver is no longer detected in the boil liquid.
possibly mercury bubbles means gas, use a respirator to be safe, we have a natural mercury 'spring' nearby quartz and close to the spring appears pink and/or red foreign mined gold unregulated may have been processed with mercury
So with such a low amount of gold, would it be more cost efficient to remove the gold? With heat or acids (like electronics)? …or is it not even worth it with that little gold?
they are probably made using a press. that means a little container shoots out and back to fill the die and it's pressed in to shape. it's not the most accurate way of doing it weight wise but it is fast.
@@scrappydoo7887 Well my idea to do it quickly, almost as if it was a mechanical process. There is so little gold, and it is all on the surface. It might only take a few seconds to do a batch. You could put a few rings on a plastic hook and dip and swirl in acid for a few seconds looking for a color change before reloading with more rings. The after you are done with a 1000, process the acid and see if the gold drops out of solution.
@@reina4969 I don't think that will work. You will end up with very badly contaminated gold and the two things you don't want in any solution. That's lead and tin
Rubies are basically compressed aluminum oxide. Maybe the slag is red because the ring had aluminum in it as well. Perhaps the ring had aluminum and trapped air and that's what the bubbles were from. Even tungsten can get air trapped in the metal so
Gold plates best to silver and silver best plates to copper and i am guessing copper best plates to lead so i guess the shine of the rings is probably due to the amount of copper added to karat gold alloys to give it that typical gold ring colour we all know.
Question: why did you use borax this time? On your other videos you use that sand looking substance that turns into glass, but this time you use borax. Also, at the beginning of video u mentioned about bismuth. And last question: why do u alternate between the electric little heater and the home made furnace with propane bottle. Im somewhat new to this but taking lots of side notes on paper and pen.
i would make about 400 ml of aqua-riga. (HCL and nitric) use it as a rinse and dip each ring in till the plating is gone the use some sodium metabisulphate to cement out the gold. You would have to use sulfuric acid to cement out the lead and then filter it before hand but if you follow streetips he explains it better
Is there an electrolysis method that you could use with having to first dissolve the gold into solution? I have seen it used before. Who knows if the yield would even pay the power bill lol.
Do you replace the cupel ever time since it absorbs all the other metals, if silver or other precious metals are present do they stay or are they absorb? Hopefully that doesn't sound too stupid just starting too learn
Is it true that the gold starts evaporating like steam when it gets to temperature? And if so, is it significant enough to be concerned about, with such tiny quantities?
@@KK-xz4rk you dont need much of an element to make a big impact in such things, only trace amounts of gold for example are needed to make a computer processor hundreds of times
Never assume. I can save you the trouble as someone who actually processes precious metals. Don't waist your time with anything gold plated. You'll need a 1000 of those rings if they are truly gold plated to equal maybe a half a gram. My guess it's a Nordic Gold recipe of elements. Throw them directly into the trash...
Thanks for answering my email and giving some advice its not as cut and dry with cupel and I'm sure I'll get it over time to see the flash you showed in a previous video of when it goes from oxides to gold ill see the flash day lol
The rings being different weights is probably because jewelry rings are different sizes for different people, That stack on the scale looked like different sizes to me.
That red was caused by my brain trying to wrap around how well you understand the different chemical processes and how to achieve the end result you are after.
That bead is so small, there's not enough gold there to have electroplated three rings, must be a very cheap alloy. The quickest and cheapest method to strip and recover any gold coating would be an Aqua Regia bath. Simple and quick, but safety first when using any of the methods of gold recovery.
I think the best thing you could have done was keep fire on the crucible and the mold as your pouring out the alloy. I think the borax would be less of a problem
This video will make him more money than the recovery did. (And that's true for most of these recovery channels.)

Considering the furnace temp is almost 6 times it's melting point, perhaps the bubbles are from the lead vaporizing.
There is a huge difference between the melting and boiling temperatures of lead - as is the case with most metals.

it could be a form of "Nordic Gold" which would make sense with tin content. Its composition is 89% copper, 5% aluminium, 5% zinc, and 1% tin.
