Reverse plating in a sulfuric acid cell is the best way to go with gold plated items. Yes, magnetic pins will reverse plate quickly in the sulfuric acid stripping cell. As you can see in this video, it took a long time to get the base metals to dissolve. The mil-spec pins I used in this video would have de-plated in just minutes, instead of taking hours to dissolve base metals like it did in the video.

The sediment is probably a salt. Just let it settle completely for at least 24 hours, or until the liquid is crystal clear. It may take longer than 24 hours. Then use a piece of flexible PVC tubing and siphon off the clear liquid and leave the settled salts at the bottom. Gold plated pins are best deplated in a sulfuric acid stripping cell.

Might have been something in the vid to make me calculate that number. If you want to do this yourself study up on it. These videos of Sreetips are very educational, I've watched everyone of them and when I start to refine I'll watch them again and take detailed notes, also there is a book that he recommends in a few of his vids (It's like a refiners bible)!! I know standard fully plated pins on average yield about 1gram per kilo of pins! However mil spec gold pins are a much heavier plated pins than your average ones. After hundreds of hours studying I think it's safe to say that you should expect 2 grams or more per kilo of pins!! Again I'd have to rewatch this vid to see why I put 7.4 grams. It might be that he got a high yield from a batch and I just did the math and got 7.4 I'll tag this video to rewatch, I don't know how soon that will be, but as soon as I do I'll give you my opinion again. Probably a little more accurate than this one! Have a GREAT Day!!!

After precipitation I always filter the gold powder out of the green liquid. Then, after rinsing the gold while it's still in the filter with a little hydrochloric acid, I dump the wet filter and the gold back into a clean beaker. I add some fresh hydrochloric acid, cover the beaker, and place it on low heat. Then I add just enough nitric acid to completely dissolve the gold a second time. The filter paper disintegrates and gets filtered out during the filtering process. After filtering I precipitate the gold a second time. This second refining really cleans the gold up nicely and gets rid of the green liquid completely.

Brass, an alloy of copper and zinc, is highly soluble in nitric acid. Iron and steel cause problems because it don't dissolve as easily in nitric. Also, when the gold is dissolved in aqua regia, if any metallic iron is present, the gold will tend to cement out on the iron. The iron based gold plated pins are best processed in a sulfuric acid stripping cell.

If they are megnetic due to nickel then they will go right in with the non-magnetic pins and digest nicely along with everything else (accept the gold which is not soluble in nitric acid).

Hi sreetips! Can you give me your opinion? What you think about to plunge the pins directly in aqua regia and leaves them enough time to remove the gold plated? Obviously this will add a little amount of base metal within the gold, but maybe it can make the process faster, saving reagents and after that, the gold obtained can be refined by inquartation method. Thanks!
@sreetips7 жыл бұрын
While this seems like a shortcut it will end up using more time and reagents. The main problem is this; the base metals are going to be copper or brass. The AR will dissolve the gold, but then, in accordance with the reactivity series of metals, the gold will immediately cement out as a gold powder onto the base metals - this will use much of the acids requiring additions of fresh acids to keep the reaction going. Eventually, after adding much acids to get everything to dissolve, the gold will no longer have anything to cement out onto and the gold will stay in solution. But the solution will be very dirty, full of base metals and chloride salts. Also, if there is any silver present, the HCl in the AR will react with the silver forming silver chloride. The basis of recovery and refining is to selectively removed impurities. That is why the first step is incineration to remove grease and oils, then dilute nitric to remove as much silver (if present) and base metals as possible. Then, when all that is left are gold foils (because dilute nitric will dissolve base metals but it won't dissolve the gold) then it is just a matter of dissolving the gold foils with AR or chlorine. The resulting chloroauric acid solution will be fairly clear and clean of base metals and should precipitate quite nicely. Dissolving the gold foils with chlorine will eliminate the need to denoxx the solution because there will be no nitrates to deal with, because nitric acid was not used to dissolve the gold. Chlorine will dissolve just about any metal, even platinum.

Perfect sreetips! I have a good amount of plated pins to process and I want waste the least as possible of gold. So I'm thinking about the best way to do that. Thanks a lot.
@sreetips7 жыл бұрын
The best way to get gold from gold plated pins is to reverse-plate the gold off with a sulfuric acid stripping cell. Please see my video on how to build and operate a sulfuric acid stripping cell.

Gold from pins you add 1 spoon if SMB video prior to this one you added 8 spoons of smb. What is the criteria for quantity? Both beakers were not that different. Rules?
@sreetips4 жыл бұрын
I just added SMB until I thought there was no more gold in solution. When first starting out add a spoon of SMB then test with stannous. Add another spoon, test with stannous. Repeat until the stannous test is negative. If excess nitric is present (common for beginners) it will take much more SMB until all the excess nitric gets consumed. In time you learn how to add just enough nitric to just dissolve the gold. Then the amount of SMB required will be much less.

working on airplane throwing and changing daily yellow pins so am sure time it's aircraft parts must be more gold on it. but the operation is to complicated with all this kind of acid. I have nitric acid can I just let pins on nitric for days and see ?
@sreetips7 жыл бұрын
You'll probably end up with a mess and recover no gold. In the video, I used nitric to dissolve the brass so I could recover the gold foils For refining. I did it for demonstration only. This is not the best way to recover gold from gold plated items. The best way is to use a sulfuric acid stripping cell to reverse-plate the gold off the gold plated items. I made a video that shows how to construct and operate a sulfuric acid stripping cell.

Hey streetips , are u available for one on one help? I have experience with gold recovery from E-Waste and gold plated jewelry. But haven't done it a few years. Will be doing a sulphuric cell, AP and nitric acid. I've got a decent amount of material and I want to process it all.

Hello, unfortunately I don’t offer any kind of training or tutoring. And I don’t have much experience with escrap. I’ll try to answer questions if I can.
@hunterholley77087 жыл бұрын
Is there any chance for profit with this process, or after costs for acids, do you generally come out with about as much value in gold as you spent to get it? I am interested in doing this myself, but do not want to lose very much money.

No, there was no profit. I bought the pins for the purpose of making the video.

Ok. Basic question here. What the hell is a "military-spec gold pin"? What are they used for, and where does one get them?
@sreetips6 жыл бұрын
These type pins are used in plug-in type connectors where high reliability is required such as in military weapons systems. They usually have a thicker coating of gold than say, your cell phone SIM card connectors. If the thin gold on your cell phone rubs through then the only consequence is you won't be able to call. But if your getting shot at and your defensive weapons won't work because saltwater corroded the connectors - BANG - your dead. They can be bought on eBay.

I know this is like 4 yrs later but if one would grind up the pins would the reaction take less nitric to produce better or quicker results and by any chance you can be hired as consultant for future simply because i only trust 2 ppl I can tell so far no offense to others you are one of them cody being the other

Chopping the pins up would expose greater surface area and speed the reaction.

Is it necessary to kill the excess nitric? Whats the difference of using sodium metabisulfite and ferrous sulfate for precipitation? is there any advantage of using sodium metabisulfiteto precipitate the gold?
@sreetips7 жыл бұрын
Excess nitric in with the dissolved gold causes problems. It should be "killed" before precipitating the gold. Sodium metabisulfite will tend to bring down platinum group metals if there are any in solution with the gold, especially if excess nitric is present. Ferrous sulfate will not precipitate platinum group metals.
