Inquarting With GOLD FILLED Instead of Silver

[@williamfoote2888]

-That white gold in your 14k portion is Rh plated. -You could use the Au electroplated material to inquart. The Au is plated on brass, which is Ni and then Au electroplated. Just assume that all the electroplated weight is 'inquart.' You'd be adding in the same Cu and Zn that's part of your Au filled material. -That junk metal is 'brass' or 'Zn diecast', that is zincate immersion (Na2ZnO3) coated, Cu flashed, Cu plated, Ni flashed, then Au flashed. Zn is just as useful to inquart as Cu or Ag. It all comes out when you do your HNO3 boils. -The material at the bottom of your melt dish is likely stainless steel. -I'm surprised at how little slag you have floating on top. That'd be your Zn or maybe Pb oxides. Looks like they might have been rinsed out into the drain when you spatter cast your melt into the cooling water tank. -The activity series isn't going to predict reactivity with acid. If anything, the reaction you got would be from the amount of Cu and Zn in the inquarted gold. Whatever Zn you add to your process will pas all the way through to your final Fe waste stream and be discharged in any liquid supernate. -Jeez. I didn't even consider Sn. -That white sediment on the bottom of the beaker, after the HCl boil, is your PbSO4. -Double, triple or even quadruple up on your filter paper for the Buchner funnel. In the old days, we'd use an asbestos fiber filter mat. I'd think you could use an activated carbon layer on top of the filter papers to help you get your clear solution. Of course, you'd need to add the carbon to your filter paper stash for later metal recovery. Yes, the filtration step will be slow, but less sensitive to high pressure vacuum. That IS nice Au! Long road to well done!

[@lazerwolfdiecast]

It would be cool to see a video explaining the cost to profit ratio. Like how much you spend on chemicals, electricity, and metals compared to the value of the finished product.

[@anthonyrstrawbridge]

I believe it is negative. The scrap metal cost is fixed at scrap value. The refining costs are expensive. If you add up the two costs it is a big loss. Also, a percentage of the scrap material is lost during refining. The gold value in dollars per weight is the same regardless of purity. I don't think the cost in dollars is his mission. The silver from karat scrap is very profitable IMHO. 👍 The costs of equipment repairs, replacements, and upgrades and now replacements again, has been significant.

[@catch22frubert]

I love to see the honest results of experiments like this. The bulk of the brass is copper, which should be no problem when inquarting, but that 15% zinc and the lead tin soldier really changed everything. Awesome video Sreetips. Its cool to see you experimenting and showing why its better to stick with a sterling silver inquartation when possible. If not, use pure copper or pure silver.

[@Welshman2008]

Fascinating video as always I thought the splatter board idea was quite ingenious in its simplicity.

[@disgruntledtoons]

Your most perfect bar yet, and at today's spot price just a bit over $7300. And it seems that the high-purity gold precipitate tends to clump together (so that less of it gets poured off with the waste solution) than the low-purity stuff earlier.

[@mickg6480]

'Atta boy. That's more like the result we're used to. And the pour lines on that little bar are amongst the nicest I've seen from you lately.

[@guygordon2780]

Not only is the Zinc more reactive, but as it is removed early, it's absence will leave channels through the remaining mostly copper alloy. Those channels will add a lot of surface area, thus speeding up the remainder of the extraction. You might find yourself using this more often, to save time. Lets hope it doesn't add any problems. Of course, you could also inquart using a mixture of sterling silver and gold filled scrap.

[@DFPercush]

Might be worth experimenting to see at what percent of zinc does the gold start to fall apart and form suspensions.

[@BronzeAgePuritan]

Using silver feeds the silver cell.

[@lazyman114]

I think he spent maybe up to 10 hours extra to recover 6 extra grams from the gold filled scrap. Combined with the extra headache, I think it's not worth using this method.

[@guygordon2780]

​@@lazyman114 Trying something new always takes more time. Doesn't mean it's not worth trying. Best way to learn something new. The problem Steetips ran into is not inherent to this method. It's a problem whenever the inquarted gold is much less than 25%. At 25% you get a gold sponge.

Now this is gold content. Love the experimentation vids.

[@vinnycordeiro]

Considering that a lot of colloidal gold went to your temporary waste container while cleaning the precipitated gold, the yield was really good. I believe it was so close to the theoretical yield because of the extra from the gold filled material, about 5 to 6 grams. Anyway, that's a messy alternative to be used when you have no silver/copper readily available, but it is surely not ideal.

[@daftwulli6145]

well sure it is messier, BUT on the other hand you do 2 refinings in one, scrap and carat, so it seems like it does save work, and quite a bit

[@kwinterburn]

Don't know whether this might be useful but I used to have to extract settled sediments from the liquids, the problem was you couldn't Syphon off all of the liquid, so I got a wine bottle with a plastic screw top, cut off the bottom with a tile saw, then you could fill with the liquid and leave it, the sediments settled on the plastic cap right in the neck, so you could Syphon off almost all the liquid without disturbing the sediment, it's also how the painters extract pigment from water based paint out of brushes, it just flows out of the brush and falls to the bottom without circulation,

[@tonyquark493]

Wow at the final dissolve in aqua regia, it seems the solution was so saturated with dissolved gold I think that's why it was having trouble dissolving more until you added more Hcl!

[@roberthayward9299]

Great work as usual Sreetips. The zinc and copper will use a little more nitric acid than the silver would have because these metals both have a valence of 2 rather than the valence of 1 for silver. Interestingly, under some controlled reaction conditions, zinc will form nitrous oxide "laughing gas" instead of the brown nitrogen dioxide that usually forms.

[@sreetips]

I noticed some white foam during the nitric boils.

[@gratshor]

36:39 You no need to waste hydrochloric acid for silver test. Use for it medium to high saturated solution of sodium chloride (cooking salt times cheaper than muriatic acid). And salt will not rise acidity of solution, but gives same precipitation result as acid. 36:50 That green cloud is copper dichloride (CuCl2) and possibly zinc tetrachlorocuprate (Zn[CuCl4]), both salts quite unstable(especially second) in nitric acid or it's salts solutions 43:44 Nasty ortostannic acid (or fine tin oxide, from G.F. material) clogging filters in minutes or go though it if not fine enough. Using filter "sandwich" will help alittle. Filter Sandwich from top to bottom: rude filter (cotton pad), semifine filter/filters(quick and/or medium flow class) and fine filter (slow flow class a.k.a. "blue tape"). To prevent forming tin oxide add citric acid as inhibitor (about 24 gram per 100 ml HNO3) and avoid to heat solution above 50°C. 53:46 forgot stannous chloride test

[@apveening]

About that silver test, I'd say it is inconclusive, led chloride will also precipitate. The way to distinguish led and silver is to take a bit of that precipitate, (try to) dissolve it in ammonia and add some potassium iodide. Led chloride won't dissolve in ammonia and silver iodide will give a nice, bright yellow precipitate.

[@sreetips]

Or, just add a piece of copper. Silver will cement out, the lead won’t.

[@sreetips]

I didn’t do stannous at a couple spots. I’m so used to not do it then I forget while shooting the video.

[@apveening]

@@sreetips Works ... in a non-acidic solution.

[@gratshor]

@@apveening Lead chloride precipitate only in concentrated solutions, in diluted solution it's redissolves. Solubility difference between lead and silver chlorides is significant: for PbCl2 is about 1gram per 100ml (at 25°C), and for AgCl is about 20micrograms per 100ml (or 0.2gram per tonne)

[@bikinglikebecker]

is home refining profitable? aside from when you purchase for demonstration purposes & overpay... Also I was thinking Instead of just doing a straight nitric to pull out the base metals only, you could do it another way without having to inquart. Why not do aqua regia to put all metals in solution then precipitate/filter & do nitric pulls when it is a dried powder? I think it would do it better with fewer nitric boil pour offs... I could be wrong, I have as yet to do my first refine with all this e-waste from computers I found that I couldn't just rebuild & give away... Surprised that some of these old processors can go for quite a bit of cash... same as the ram & other hardware... almost like it was when it was cutting edge technology... lol..

[@sreetips]

You could put the karat gold directly into aqua regia without inquarting with silver. But two major problems would arise. 1) it makes a very dirty solution that looks like used motor oil. 2) any of the gold that contains much silver would passivate. The HCl in the AR would react with the silver and form a tough layer of silver chloride that would shield the gold from the acid. To remedy it must be removed before the gold will go into solution. Both problems are completely eliminated by inquarting with silver (or clean copper) and parting with hot dilute nitric boils BEFORE going to aqua regia. Plus, I refine silver and the first step is to dissolve it in hot dilute nitric acid. So why not use it to inquart? Like refining both metals at the same time.

I refine silver also. The 1st step is to dissolve it in hot dilute nitric. So I missed an opportunity to get some more silver dissolved. I have much sterling that needs to be dissolved. But I’ve also got a bunch that needs to be melted, granulized, and run through my silver cell. I’m way behind on everything.

[@Sanzus2]

@@sreetips the other thought would be to re-melt after the first couple of nitric acid baths when you are no longer getting a reaction and most of the zinc is gone. You would be left with mostly copper and some silver and it might keep it from breaking down into colloidal.

[@jerryellis835]

Considering the amount lost in waste that was a excellent total. Way more than I thought. No stannous testing, was it not really necessary on this one or was it cause you knew some would stay suspended ? 1 other question I always wanted to ask, would it be worth getting a digital karat reader? I know a lot of pieces not plumb would always be either under or over karat stamp. Would that interfere in inquarting ?

[@sreetips]

There’s a “Goldie locks” range for inquarting. Too much silver and the gold will crumble to a powder making separation of the silver difficult to pour off. Too little silver and the nitric may not be able to penetrate.

[@ghosttwo2]

When you get the purple gold nanoparticles in suspension, I wonder if adding a small amount of SMB would act as a surfactant, and cause them to condense? I know that it can make particles of many atoms when it reacts with chloroauric, but I wonder if it can have the same effect on particles in suspension. Next time you get some 'purple gold' it might be worth putting some in your spot wells and trying different remedies like copperous, or even lye. If you can find an additive that efficiently condenses colloidal gold, it might open up other refining options.

[@sreetips]

Gold filled takes several days to get it done. I can refine gold to high purity in ten or twelve hours. Combining the two processes into one, like in this video, seems that it defaults to to longer of the two processes, time wise.

[@sreetips]

I may try it again with a smaller quantity of karat scrap and reduce the amount of gold filled I add.

[@guygordon2780]

@@sreetips The basic idea was sound. But yeah, it was a large amount for a trial run.

[@troynixon9467]

Awesome video as always , was quite the adventure !!

[@dannomight1980]

Would it be beneficial to add an inline whatman filter when siphoning the liquid out around the 31min mark or just in general? Might be a way to save some time and gold in situations like this video? Heck I may just order some for my future endeavors 🤔 Most men can always use new tools or equipment right?

[@sreetips]

Right!

[@ericshuping3651]

For the purpose of inquartation, how do you know how much gold-filled material to use? Or do the constants you use for sterling silver still apply?

[@sreetips]

Should still apply.

I've been learning so much. I might try my hand at metals recovery.

[@dynorat12]

if you use a stainless screen that's touching the water you can get a finer beads of inquarted medals

[@chrisvanderburg5568]

Would it be more efficient to remelt the black gold powder and inquart with silver so you can refine in a normal fashion instead of pouring off small amounts of suspended gold powder each and every time you drain off a rinse?

[@sreetips]

I’ve done that when I added too much silver and the gold crumbled to a powder. Remelt, inquart with silver and proceed as usual.

Thank you for the demonstrations of the process of “Aqua Regia”.

[@sreetips]

Glad to do it.

[@JustJeff62]

Absolutely excellent video Sir Sreetips!💯This is exactly how we learn brother! A huge THANK YOU!!! You did a incredible job cleaning up that solution! Bravo!!! Is there a difference between Stump-out and Food grade SMB?

[@sreetips]

Thank you. No difference.
