Recovering the gold plating from these rings and jewelry a customer sent over for me to experiment with. These rings should have some gold plating on them and we are using some assaying and metallurgy techniques to determine the amount of gold that we can recover. We use the cupel method for determining the weight of gold in 3 rings and also melt down several rings and use an XRF gun to determine the percentages of metals in the entire alloy.

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.

This is the first time I saw this video. I remember those rings on e bay. The seller claimed to have several 50 gallon drums full of them. I think 700 lbs. He was trying to sell them for gold recovery. I refine gold so they caught my eye, but my brain said no way. The company that produced them new darn well they were worthless or they would never have let 700 lbs of them just walk off. Think about it. 1% of 700 lbs, 7lbs of gold, not. They were made for the movie Lord of the rings. Note the markings.

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.

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.

Gold plated is generally not worth going after unless you have a lot of it. Gold filled, if you find it and want to extract the gold from the jewelery, it's the way to go. GF is any where from 2% to 4% gold by weight. It's a cheaper option than jumping right in to the high purity 14k 18k jewelry.

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")

If these rings have ANY gold in them at all, the best way to extract the gold in them cheaply is a sulfuric acid stripping cell. All you need is a battery charger, a pyrex dish, A Lead Bar and some Sulfuric acid Drain cleaner. Since the rings have a large surface area, they should be easy to de-plate quickly.

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 ?

@@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.

@@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

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.

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.

1) Try an acid test on the gold for purity. 2) You should do the math and know how much gold by weight the button needs to be and what purity it needs to be to break even. 3) In this effort that button, even at 24k, didn't pay for cost of the electricity or the Cupel.
