Question! You cracked a glass funnel in this vid and said you were going to put it in a bag and bust it up for boiling granules!!! What are boiling granules?? And what do you use them for??

[@sreetips]

Shane. When boiling a solution, heat will build and cause little steam explosions inside the vessel. Sometimes they can actually be forceful enough to break the beaker. Adding an inert piece of glass (or stone) to the solution will eliminate these steam explosions.

[@SCHTRAM]

Why melt silver together with gold then remove the silver? Does a silver-gold blend create some form of reaction in the gold that is left after removing the silver?

[@maximilianibel]

I'd like to know too. I suspect that this makes it easier to get the proportions of acid right so that you end up with silver and gold in solution and minimize toxic chlorine gas during the process. But then, why not add enough silver to the 14K gold to make it 10K gold and then go with a uniform 10K gold alloy ?

[@sreetips]

The nitric acid will not penetrate 14k gold. I add silver to reduce the karat down around 6k or 7k. With the gold content this low, then, and only then, will the nitric be effective and get all the silver and base metals out.

[@maximilianibel]

ah, so the idea is to create the low gold-percent alloy such that by extracting the silver we end up with a sponge-like gold substrate that can be dissolved faster in aqua regia ?

[@sreetips]

Max, that's a beautiful, concise, and compact way to get that point across. I couldn't have said it any better myself. I may use your words in a future video about inquarting. Thank you!

[@Kakiro_Miro]

Lovely video, next I have to see if you have a video of working the silver.

[@Impatient_Ape]

Since nitric acid isn't cheap, that brown nitrogen dioxide gas we see is money going right out the fume hood exhaust. I'm not sure if it's cost effective or not, but you can bubble the nitrogen dioxide gas through concentrated hydrogen peroxide to reform nitric acid. The acid will be relatively pure, but you will likely have to distill the acid to bring it back up to azeotropic strength. Concentrated peroxide isn't cheap, but it may be worth a cost analysis. As you probably know, that exhaust NO2 just ends up acidifying outdoor precipitation.

No wonder it costs so much for certain types of luxury metals

[@bormisha]

The cost comes from scarcity. Refining is generally difficult, no matter what substances. Yet, they have managed to optimize and automate the processes so that the refined substances cost nearly nothing. Not so with gold. It's just a scarce element.

[@josecqneto]

Dude, that was dope. I did some math here. Today (April 24th 2019), you had a total of U$ 5960 in 10K and 14K gold. After the refining, you got a amount of gold worth U$ 11185. That is a U$ 5225 gain just by purifying the gold, if what you say about the final bar being a 24K gold. If you recover all the acid that you used, this is a monster gain. Also, you should account the energy you spent and those powder reactants. Plus, you can take into account that you have a lot of silver in solution that could be purified also, and the palladium. Great video!

[@sreetips]

Jose, the amount of pure gold in both 10k and 14k scrap was 279 grams. The amount of pure gold after refining was 274 grams. There was actually 5 grams less after refining. This is normal because the amount in of gold in karat scrap is never plumb. The amount that you calculated, $5960, is not correct.

[@Biomorphs]

Inquarting - if you search it on you tube - Cody'sLab has a great video to explain it all

[@SV_Try_Magic]

when you primary smelt gold from ore it comes out as electrum which is the base of white gold. Lots of that unrefined white gold was used to make jewelry over a hundred years ago. They just didnt go any further because it wasnt worth it. And they were right its not worth it because he probably spent several thousand dollars in acid, sodium Meta Bi sulfate and other chemicals and glassware to come out with the bar of gold.

[@sreetips]

Adding the silver, then removing it with nitric acid, does an amazing job of cleaning the gold in preparation for refining the gold with aqua regia. Trying to dissolve the gold "as is" has two major flaws: first, karat gold contains silver. The hydrochloric acid in the aqua regia will react with the silver in the karat gold forming silver chloride and make filtering a nightmare. Second, if the silver content in the karat gold is high then the HCl in the aqua regia would cause passivation. Passivation is a thick crust of silver chloride that forms on the karat gold and shields the gold from the acids. Once this layer forms it must be removed before the gold will dissolve. Adding silver and parting with nitric acid, if done correctly, completely eliminates both of these problems. If I tried to dissolve the gold without inquarting with silver then I'd still be out there trying to get the gold cleaned up, right now!

[@sharudd]

Ok I get the nitric acid to dissolve the unwanted metals. I get that the karat gold has silver in it. But why add the extra silver. That's where i'm confused. Why not just add nitric to the karat gold in order to dissolve the unwanted metals before the aqua?

[@MrENT18]

@@sharudd So I've done some research on this since asking this question yesterday. It seems that if you want to remove 100% of the gold from the karat gold (or as close as possible), you have to add silver so the gold atoms are further displaced by the excess mixed in silver. This makes it that the silver has less of a chance to inhibit the dissolving of the gold atoms by means of creating a protective layer/capsule around the gold atoms, thus ensuring the maximum amount of gold gets dissolved by the acids. As recommended by @Biomorphs in the comments, Cody'sLab has a great video on this (just look up "Cody'sLab Inquarting"). Hope this helps.

[@Dealazer]

45:10 You got more Platina in the solution I believe? That means that nitric acid and muriatic acid is dissolving the available browned gold, but the mixture of browned cakes just opened itself that leads to more amount of different metal? Since it would be better to ground the brown cakes first with a machine grinder? Or is the process of the brown cakes already dissolved? But perhaps the grey colour in the beaker is probably something that weighs more than Gold? Its molecular weight describes either concentration of gold or perhaps other metals all ranging from palladium to silver, but silver should have been dissolved with both acids. But then again are we looking at perhaps Platina as its weight is so heavy that it doubles its presence to lay at the bottom? As Platina is 195 weighable as molecule AU?

[@sreetips]

You sound very knowledgeable. Can you post a video and show us how it’s done please?

[@Dealazer]

​@@sreetips Sorry, I wish I've had all the laboratory like you so I could at least show this, wait 2 more years and I'll show you the things that I go around and think. In my belief, there is this that molecular weight often makes Platina residue as blackish coloured substances that sometimes end up in your filters and are the last residue in the solution. Because of the high molecular weight of 195 Platina is as well hard to split up from the particles it is mixed together with. But it also would be behind in the beaker. Some would think that the steel would be residue, but on the other hand, steel is an alloy by reducing the carbon like in Iron. Correct me if I'm wrong. If acid does not bite steel then it's different measure about that. So we are most likely are talking about steel and Platina together being residue in the beaker. Splitting steel from Platina I believe you will need to use the lead method like perhaps cleaning gold bars. By molecular weight, you might end up having Acid on the bottom of the solution that is mixed with water over a long period of wait. By this, you don't see it but you can know what you see that the acid is on the bottom of the beaker after some time. Here we do not speak about Acid that has been used or is with a different solution than just water. Since water has low molecular weight than Acid. And what is with most molecular weight does end up on the bottom of the water solution. Water perhaps has weight 18, 2 of Hydrogen and 16 of Oxygen. And the molecular weight of Acid is also important to know. I believe that measuring the molecule weight has a big issue in your chemical procedures, as it states what often is on the bottom of a beaker after processing. I've been super studying all your videos over time and liked all of them, so I've also been studying these things I wrote about. It is just that I know the logic of this, not fully being educated at a school. This chemical processing gave me my life back to reality means that my life has some sort of meaning. It was hard for so long not having a purpose to live. Thanks for all your videos! They are a great motivation for a better day. Soon I will be ahead and having similar laboratory. Not amateur laboratory-like out in the woods cooking with acid and dying younger by the fumes that come out. People seldom do see your face making the videos, and seeing you using a professional mask and eyeglasses.

I'm going to use this equation in my future videos to show the reaction of sulfamic acid in the solution. Thank you!

[@aga5897]

I found on wiki : (NH2)2CO + HNO3 => (NH2)2COHNO3 The molecular weights are close enough (60 & 63) to call it a 1:1 weight ratio of urea:nitric, if it was 100% concentration - you'd need to adjust for the w% of each. The major problem with calculating/predicting what happens in refining is that it is a really complicated mix in the pot, not just those two chemicals. Another thing is that HCl & HNO3 are gasses dissolved in water. Heating them makes them more reactive, but it also boils them out of the water. Basically if you start with exactly enough HNO3 to react with X grammes of urea, some of the acid begins leaving the pot as a gas as soon as the reaction begins (it's exothermic) so you'd have to add more nitric as you go. Calculating how much more to add (and when to add it) is way beyond what i could calculate.

[@sreetips]

(NH2)2CO + HNO3 => (NH2)2COHNO3 looks like the HNO3 is still there.

[@aga5897]

sreetips it is, just ionically bonded to the urea.

[@J.funderberker]

You seems a little confused by the math so hope this helps Multiplying by 1.265 is just increasing your starting weight by 26.5% Multiplying by 0.635 finds 63.5% of your starting weight

[@lilBabyBornInCalifornia]

the only one confused here is you... like what "starting weight" are you even talking about? i dont think you understood his calculations at all

[@antigen4]

he's right- the multiiplier makes ZERO sense - it assumes that 14karat gold is more 'pure' than 24k gold

[@lilBabyBornInCalifornia]

@@antigen4 well, what he was trying to do was make both types of gold into the same karat.... its implies the 14k needs more silver to bring it down to the same level as the 10k

[@azmika85]

The way I'm understanding is that he need's a quantity of silver to gold. 10k has less gold therefore needs less silver, 14k has more gold and needs more silver.

[@elbystump56]

I'm curious why do you inquart rather than just throw the karat stock straight into the nitric acid? What effect does adding all that sterling have that couldn't be obtained without inquarting? It seems like a lot more work dissolving all that added sterling rather than just dissolving the silver already in the karat.

[@sreetips]

Seems counterintuitive I know. But adding the silver enable the nitric to penetrate. Without it the karat gold would just sit in the boiling nitric, looking at you, unaffected.

[@ugsisr]

I have a good friend who recovers pure precious metals from what others would call "Junk" and he does well. Its amazing where,what and how he gets the "Junk" that he uses to recover them from. Nice video....Thank You

[@simonci5177]

So what was the total price off all 10k + 14k gold +silver +all chemicals. VS pure gold on the end. Is this some big profit in doing pure gold? Price of 12k gold is half price of 24kgold. So what is the point of you making pure gold? There is no proffit in that

[@sreetips]

While not necessary as you point out, I refine it for several reasons: 1) karat gold contains silver and platinum group metals, you get credit for neither if you sell it, while I get to keep them both because I refine the metal myself. 2) I love doing it. 3) I get to make cool videos, the best on KZbin, on how to refine precious metals and share them with you!

[@simonci5177]

Yea, great video and interesting hobby. And bar looks hipnotizing good. Im just asking from the side of potential financial benefit of if. So how much silver you get from this extraction? VS what was the cost of chemicals you used. Because they say in this link, that any mixed gold "may contain some silver " so it may be Even 0%. And you "Lost" 5.5 gr of gold during extraction. I think price of lost 5grams of gold is bigger loss than potential random unknown gain of silver. I think financialy you lost more than you gained. www.jewelry24seven.com/metal_facts.htm

[@sreetips]

Simon, karat gold is never plumb. By law, 14k gold can be 13.5k and still be stamped 14k. That 5 gram loss is normal and expected. If you are looking at it from a profit potential then that has to be done when you buy. You make your profit when you buy the material. I paid between $5k and $7k dollars for the scrap in this video. I estimate $100 for chemicals, glassware, utilities, rent, taxes and insurance all in. Please see my video titled "how to make a profit refining precious metals" - it may have some answers for you.

[@simonci5177]

Im just thinking. How it works... So you paid 12.1k and result was bar 11k. I was right. You loost 1.1k. Hm... Than Maybe is more profit to buy pure 24k, mix it with cheappest metal to make 9.5k and sell it as 10k? (Just thinking) and zero loss on chemicals

[@sreetips]

I paid $7.1k, not 12.1k

[@kvjqxzz5905]

what a great vid, beautiful bar - gold will go up a lot in the foreseeable future, good idea to hold and appreaciate...

[@danielconverse8189]

Not to mention of course how much the total cost of equipment is that would allow you to complete the entire process from start to finish. Count the entire cost to a person to set up an operation that would allow a person to make from, start to finish, the pure gold bars.

[@tipxking9944]

Why did you use silver when initially melting your gold pieces? Was it to make the process of heating the reaction quicker? Is silver a necessity towards the valuable gain?

[@sreetips]

Yes! Adding silver reduces gold concentration so that the nitric can penetrate. No silver, no reaction.

[@tipxking9944]

Thank you for your quick response. Do the silver have to be pure silver?

[@gordendavis3585]

Hello Sir i really appreciate your videos very helpful and informative.. My question is: what is the optimal temperature for Nitric Acid to quickly dissolve all base metals in a timely manner ?

[@sreetips]

In my experience, the more heat the faster it reacts

[@gordendavis3585]

@@sreetips Thank you very much sir.. i am planning on doing my own refining, im retired military and looking for a new career now.. your videos are completely comprehensive..

[@ramonadavis3556]

Why did you add silver to the gold in the first place? Couldnt you have just melted the gold and used the nitric to get rid of the other base metals? Probably a dumb question to you, but i would really like to know.

[@sreetips]

Ramona - adding silver reduces the gold concentration and allows the nitric boils to penetrate to the core of each piece. This removes almost 100% of the impurities leaving pure gold that is very close to three nines. Inquartation - one of the most valuable refining techniques that I’ve ever learned.

[@ramonadavis3556]

[@zacharyw.beavers5005]

Do you know that the Nitric/Water combo has run it's course when the fumes cease? Or are you just going by the time you have it sitting in the solution?

[@zacharyw.beavers5005]

Also how many times do you usually run it through solution? Is there a standard method you use as far as how many times you purify it?

[@zacharyw.beavers5005]

I can tell when you do the 5th treatment that the red smoke seems to be almost non existent

[@zacharyw.beavers5005]

Also, when you're adding Sodium Metabisulfite, the color of the foam indicates wether or not there is more Gold to be precipitated?

[@theononas9137]

Why do you add silver? wouldn't that dillute it to make a lower gold alloy? Or is it added to substitute the gold bonded to the other metals to extract more pure gold? just curious of the expected end result

[@sreetips]

Inquartation: adding silver to reduce the gold in the alloy down to 25% so that the hot nitric boils can penetrate and dissolve everything out leaving only the gold.

[@rb3537]

I have a question about saving time. once the metal has been inquarted. instead of melting into the drops in the water, couldnt you melt into small bars,the run through a rolling mill until its very thin? Then, use the nitric acid so you dont have such thick globs of metal to work with?

[@sreetips]

possibly, but I've never tried it nor have I heard of any of the pros doing this.

[@panikrev175]

If the alloy was rolled out and then cut into sheets or strips, they will stack on each other like decks of cards at the bottom of the reaction vessel and less surface area would be exposed to the acid. You would then need to separate them and by doing so crush the gold sponge into a powder. Seems like more work and possibility for loss.

[@richardnl5193]

C. M. Hoke Refining Precious Metal Wastes page 39. PRELIMINARY TREATMENTS You first want to get your material in such form that it will be easy for the nitric acid to reach the base metals and dissolve them. The treatment will differ for different kinds of material. Old gold jewelry, clippings, and old dentures should be hammered flat and rolled thin, the thinner the better. Every minute at the rolls saves many minutes at the acids. Feed the pieces into the rolls with a little scoop whose sides have been cut out so that they will fit against the rolls closely; or put them on a piece of paper, and feed in paper and all. Cut the rolled pieces up into short lengths, twisting them so they will not lie flat in the acid; then anneal. And further on the following pages. Without Inquarttion! And many thanks for the uploads, much appreciated Best regards, Richard.NL@@sreetips

What are boiling granules?

[@sreetips]

Pieces of glass added to a boiling solution to prevent the solution from "bumping". Bumping happens when steam bubbles build up heat and release it explosively. Sometime with enough force to break the beaker. The boiling granule wil draw the heat and prevent the boiling solution from bumping.

[@JeffreyCVogt-ch9yf]

@@sreetips that is something I've never heard of! I love learning something new, thanks for the info and your great vids.

[@uncle_thulhu]

I assume those constants take into account the base metals already present in the karat scrap? So the constant for 12k would be x1, not x1.5, right?

[@sreetips]

Correct.

[@RenegadeADV]

Seems to me like running the gold BB's though a set of rollers to flatten them out would really cut down the amount of time it takes for the process to work, and the amount of solution required to dissolve all the non gold product.

[@sreetips]

Possibly, if time was critical. But it would add another step in the process.
