Karat GOLD in Aqua Regia No Inquartation

[@BenjaminSteber]

Congratulations, everyone who pestered him about 'Why do you inquart with silver?' Now you know, and he made a royal mess of a demonstration for you.

[@jonpierce8342]

Some folks just have to learnthe hard way... 😕

[@kailuagarage]

Seemed the same in the end

[@nacota7559]

And we all learn! This is for us that are students right?

[@BenjaminSteber]

@@kailuagarage I will admit that I was surprised with the yield. I was not surprised at the repeated refining needed to clean out the gold, and also not surprised that the weight was short. That silvery button holds the rest and there's no way to get that out without inquarting at this point.

[@hot_wheelz]

​@@kailuagarageyeah not really. When you're running a business as sreetips is, the Idea is to make money. If you wasted this amount of time and materials everytime you went to refine some gold, you'd quickly find yourself going broke.

[@RDJ-v5j]

Thanks for showing us the “why.” Your lessons are so impactful.

[@scottodell7188]

"Burn all the people off of here"🤣

[@mrimmortal1579]

For those saying “you were only off by 0.6g, that doesn’t seem like enough to go through the trouble of doing it the other way”, keep in mind that this was a very small batch, and that very little of it was 18k to start with. On a much larger batch, or a batch with a much higher percentage of gold, the losses would be even greater. Not to mention the fact that he is still left with the process of refining the button of mystery metal, as well as treating the mystery solution prior to disposal. Plus, there is always a small chance that some of the pieces of scrap gold were miscategorized, which could mean that his actual yield may have been several grams higher than what he estimated, which would mean that his losses by not enquarting could quite possibly be higher than 0.6g (the only way to know for sure would be to refine the mystery button by itself to find out if there is any gold left in it).

[@IAmNoggin]

You did it wrong so we don’t have to! Thanks for taking one for the team!

[@julianalcorso5703]

Agreed. The cost of nitric in Australia is so cheap that inquartation is the only way to go. Also on my 1/2 kilo batches I dont want losses this high.

[@AndyGraceMedia]

@@julianalcorso5703 Yes, I'm amazed how much more expensive nitric is in America, but then again we more than make up for it in the cost of our beer!

[@anthonyrstrawbridge]

We already know that the button is gold passivated by silver. A few good nitric boils ought to refine it to acceptable 24 karat; No? And if the nitric boils are colorless there is no need to use Aquaregia unless refining to high purity is the goal; no?

[@julianalcorso5703]

Yes but hey, you cannot compare our beers with yours, well you can but it is an unfair contest. Back to Nitric, I can get a good industrail quality nitric of $4 Australian per liter. pretty good really. same with HCL but

[@thehaze1972]

Works if you are out of silver for some reason, the yield was a surprise to me as well, was thinking it'd be around 30g. Nice to follow along on your experiments Kevin, thanks for sharing and big thumbs up!

[@patduford3488]

Another great video. Thank you. You're showing us the wrong way to do it so we don't have to make these mistakes

[@kahnfu-zhin8627]

I’ve heard that if you inquart the gold with silver first, the procedure will go much smoother and the yield will be a bit greater. Forget who showed me how to do that……;)

[@alan11121959]

Hi there! Here's a thought, after precipitating the gold from solution with SMB, could you centrifuge the whole result to settle the gold faster? Especially with very fine gold powder, it seems to take an awefully long time to just let it settle on its own. Thanks for all the videos, I find these both educational and entertaining.

[@canonicaltom]

Centrifuging it would settle the gold faster, yes. A centrifuge spinning two 4 liter beakers (you need two for balance) would be scary.

[@sreetips]

Yes, but I’ve found that boiling also helps the fine gold powder settle much quicker. But watch out if there’s any excess nitric present. A delayed runaway reaction could cause it to boil over vigorously.

[@chiraldude]

If you could grind the raw karat gold into tiny pieces (or flatten into thin strips?) the passivation issue would be less of a problem. Not clear to me what the advantage is to this process. Faster? Less nitric used? Resulting gold looked surprisingly pure though.

[@chrism4008]

I believe this video is to show how less effective it is without inquartation, which is his normal method

[@sreetips]

Grinding gold would add another step to an already lengthy process.

[@scottindestin]

Thanks for going through the trouble to show us how to do it the long way. This was another very interesting show sir.

[@dennisflemming826]

Hi , great to see the advantages of inquartation , although having followed your channel for many years I was already a convert to the process . The problem I have is a lack of silver, living in the state of QLD Australia Stirling silver is not common and tends to disappear in to pornbrokers or call a ridicules price. How hard is it to inquart with copper? Love the show, cheers

[@sreetips]

Copper works hood. It takes more nitric to dissolve copper.

[@lylestavast7652]

love watching that refined gold sludge convert to shiny on the melt table as the torch moves around ... just cool...

[@gratshor]

13:30 It is better to mix silver chloride and sodium carbonate to homogeneous with excess carbonate (it is easier to do this in wet form or by mixing silver chloride powder with a saturated solution of sodium carbonate, then dry and melt the mixture) Also, the melt of silver chloride and sodium carbonate better to be mixed to speed up the exchange reaction 15:30 The milky gray color of the flux indicates that not all of the silver chloride has reacted; ideally, the flux should be colorless or transparent brown/transparent black. Drops of cloudy flux can be dissolved in a waste bucket

[@hot_wheelz]

While all of what you say is indeed true, if people would just follow the correct procedure of inquartation, dissolve silver and waste metals in dilute nitric then refine the gold sponge in Aqua Regia, the production of silver chloride and other undesirable by products can be kept to sufficiently low levels where they are easily filtered out and the waste saved for later processing. Sreetips deliberately made a right mess of the process in this video because some people just can't be told and clearly don't understand enough chemistry where they can reasonably predict the outcome of such well understood chemical processes.

[@saqosargis5277]

I didn't know that. Thanks

[@craterglass]

Oof. That first dissolve was so filthy, it looked like the recovery phase of electronic scrap.

[@SMOBY44]

Senior Chief, I was wondering when we get a Sreetips melt table sweeps video? That area has to have some spatter and vapor deposits from all the years. And also, what do you do with your spent melt dishes? Would make a great video series in my opinion.

[@CothranMike]

Sure would be a fine video. Crushing all the melt dishes to a fine powder by hand with a giant mortar and pestle would be a fine time-lapse wouldn't it. Using jaw Crushers set to finer and finer sizes on all of the contents not just the melt dishes, like all of his melting area would possibly yield quite a lot of gold after 20 years but like most folks I'm asking you to sweep occasionally put that over to the side and then do a recovery on that.

[@rdhunkins]

Thanks for demonstrating a technique you don’t like to use. It’s interesting to see how things don’t work well!

[@Pablo668]

Interesting to see it done that way. Not that I had any doubts, but I can see why you inquart it now.

[@Ilovegold]

The yield was quite surprising. Strait to aqua Regia will work but Inquartation is 100% the way to go

[@smijas]

Excellent demonstration. I like the inquartation methode best, on top of that. It seems cleaner and more predictable. On top of that, you have a second production line (999 fine silver) where all the nitric is reused and all the silver which was in the scrap jewellery is a bonus yield. Thank you for teaching us Sir!

[@FXGreggan.]

I also got a mystery button once after doing a batch of jewlery (I normally only did industrial gold cleanup) , didn't know what it was but it was really hard and I kept it, found a scrapper with an XRF gun and it turned out to be ~94% palladium.. with todays palladium price that was a nice bonus.

[@leonallen1973]

I am very happy that you did this demonstration, because it was something I have wondered about often.

[@julianalcorso5703]

Great to be able to point people at this vid when I am trying to explain why one should always inquart. Well done.

[@disgruntledtoons]

The benefit of inquartation, followed by the nitric acid dissolution, is that it is very consistent in its results. The silver and base metals are all in solution, and the gold and PGMs are left behind. You're not left with a beaker of heaven-knows-what.

[@David-xg3sq]

Are you able to go straight to melting the gold after parting out the silver with nitric acid? I know that continuing on with the aqua ragia will give a more pure end result but is it really necessary if you're just looking for something around 22kt?

[@sreetips]

The gold can be melted after the nitric treatments, without refining it in Aqua Regia. It won’t be three nines, but very close. Perfectly fine if it’s to be sent in to a big refiner. They will probably just throw it in with their next batch and re-refine it anyway, regardless of purity.

[@David-xg3sq]

@@sreetips thank you for the quick reply and for the information. I've always seen people refine the gold more after the nitric acid so I wasn't quite sure about stopping after the first parting. Thank you.

[@CSMMaster]

The viewers that inspired this video are fortunate you do not lash out in frustration. Unfortunately, I doubt this example will prevent them from asking the same mundane questions in future. Scotch was invented for a reason 😂

[@GokouZWAR]

I’ve been waiting for this for a while. I’ve always wanted to see the benefits of inquarting with silver cuz everyone thinks it’s a waste of time…

[@aga5897]

All i can say is Bravo ! Doing it 'wrong' is how you find out ways to do it 'right', but there is Never only 1 'right' way. Hoke researched and experimented, then found Superb ways that work, even for us dullards. I get the feeling that Sreetips could soon expand everyone's knowledge of how to refine Gold. That can only happen by experimenting and seeing what works. Maybe good, maybe bad, but very interesting whichever way !

[@shrimptrawler]

You've created a "Two Prong" approach which gives you 1) pretty close .999 fine gold in minimal amount of sreetips time, chemicals and energy plus 2) dirty

[@GlennSimpkins]

"Burn all the people here" OK that makes sense in context, but yikes outside!

[@MostlyIC]

one of the prettiest pours yet. as a machinist I occasionally do silver-brazing, where everything that gets hot gets tarnished (and I always end up spending more time cleaning up the tarnish that the actual silver-brazing), so it never ceases to amaze me that gold can be melted and poured and it comes out perfectly pure, perfectly clean, no tarnish. Amazing.

[@TrevorSenko]

Thank you for showing this, i wondered what would happen. Big fan!!

[@JaredKaragen]

I agree, inquartation is better for less cleamup/workup... but, you forgot to count the amount of NO2 you usually use in the parting process after inquartation.... several hundred ML... on top of whats used to dissolve the sponge. This method does save on nitric; at the expense of having to deal with the SNCL during workup.

[@lukasblazek5225]

1. Thank you, this was very educative 2. Why kitchen timer don't have sreetips writen on it, but 99? Was it gift? Stolen? Borrowed? Is 99 code for sreetips? etc :) So many questions came to my head whenever I saw it! :)

Where do you purchase your melt dishes at? I need to find a better source. So darn expensive on Amazon and eBay. I think I may have asked you this before and you had bought a bulk container a while ago but I’d imagine you have to had used them up and bought more by now. Maybe not, but figured id ask. Also, love it when you do videos like this that show the reason for the underlying principles of refining. It really hammers home what’s happening and makes for a greater understanding for those that don’t know.

Let it be known forever, inquartation is important! So mote it be!

[@Emu0181]

The kitchen timer was a nice addition to the time lapse. Also, on the plus side, it did turn the solution a nice shade of green

[@SilverStoll]

I will try this but with ferros sulfate instead of smb to precipitate the gold.

[@buggsy-sb3if]

I believe Sreetips has a video where he uses copperas as the gold precipitant.

[@ifyouvemadeitthisfarcongra7701]

I have even more appreciation for your inquartation process now. that was a very pretty ingot. I was wondering how close to three nines the final refine finished at.

[@jacobforrester9827]

When the chloroauric acid looks like super clear orange kool-aid, it's usually exceeding 999fine. That color should always be trade grade, provided you use a good method of precipitation.

[@anthonyrstrawbridge]

That's pretty fine me thinks. Isn't 24 karat gold just 23.5 karat anyway?

[@jacobforrester9827]

@anthonystrawbridge In jewelry stores, I think 24k is closer to 23k. I'm pretty sure that's just so you can't dent what you're wearing with a fingernail or something. Pure gold is pretty soft metal. But here, with the refining, it's far closer to 100% gold.

[@buggsy-sb3if]

@@jacobforrester9827 In the US - and probably all other countries with gold purity standards - the gold must be at least 23.5k to be stamped 24k.

[@silentferret1049]

This kinda reminds me of the episodes with the Jewelers polishing compound that you had to try and separate from the precious metals and how much of a nightmare it was until you tried the Piranha solution to dissolve the organic compounds. Proper process has a method not because its quick or cheap but because it makes the end result better and less of a mess through the process.

[@sreetips]

Well said

Thank you for the trouble you went through Sreetips ❤

[@ottolehikoinen6193]

Surprisingly good yield, possibly the excess nitric helped somehow, at least it might keep the passivation layer from forming for a while.

Love your video's. Thanks for taking the time to record, edit and upload them, I have watched just about every video you have uploaded. Quick question, have you ever tried sweeping up the area you do your melts in and incinerating your sweeps like you do for the jewelers? I know you are very careful and do not like to make excess waste, but have you ever considered sweeping up and processing your sweeps?

[@sreetips]

I sweep the table into a container. Then I add it to my cement silver when I’m making shot for the silver cell.

[@copperinquarter]

Great video, Mr. Sreetips! I don't think you had any excess nitric acid. If anything you probably didn't have enough. You ended up with 38.7 grams of gold which would require a good 35 to 40 ml of nitric acid on its own plus all the base metals in the alloys. Copper requires 4.2 ml of nitric acid per gram and I'd assume there was a lot of copper in these alloys along with the silver, zinc, etc. Passivatiom is a real problem, but I think a deficit in nitric acid is what caused the remaining undissolved metal here. Just my thoughts. Thanks for the content, sir!

That was my number one question. What would happen if you use Aqua Regia as the first step? Even if you are 0,6 g off it was a chaotic process in my oppinion. To watch the process without inquartation kinda feel wrong. With the whole inquartation you have way more control about the process in every step. This was a waste of liquids and even dealed with a Frankenstein Smoothie afterwards. Really interesting video, thanks for that.

[@hirschkuh2205]

there is way to go straight with AR, but the goldbutton must be flat (you need a machine to make it flat. maybe less than 1mm) and then the solution must be in motion all the time. Maybe you can use a stirring device. You will end with everything in the solution, but not silver cloride. it is not soluable in AR.... However, the inquartation method is the right way.

[@frantiseklaluch6605]

Hello sir, kinda brut force aproach, not so elegant, more messy, but somehow works too and needs less nitric. Well, for some materials, this might be the way to do first step gold and silver recovery. Thanks for showing us the way, you do not like and do not prefer.

So, by incinerating the carat gold, you actually expose most of the alloy to the effects of the aqua regia. Given the good amount of gold you recovered by the end, it looks to me this is a valid way to do the refining when you want to do it fast.

[@ottolehikoinen6193]

Yes fast and possibly impure, but that is not yet resolved.

[@storrmhammered]

Sreetips posted this video to demonstrate why inquartation is better, and some of the pitfalls of trying to refine when you skip that step. I've watched most of his videos; it seems that he's normally done with inquartation AND well into the first refining in about the same amount of time as the 5+ hour timelapse. After that time lapse, we still have a lot of trash to clean up and a mystery button to process later. So, when we skip inquartation: more time, effort and reagants required and SOMEHOW skipping it is the FASTER processs? For some, no amount of showing will convince them.

[@sreetips]

This is not a good way to go if you want fast. I got lucky with the filtering. I did one time a while back and it took six hours with full vacuum to pull the gold bearing solution through the filter.

[@buggsy-sb3if]

Silver is not mandatory, but he can use impure silver or sterling silver to do the inquartation. The silver is then precipitated as the chloride - which he uses in other processes, or recovers separately. Copper also works fine, but requires twice as much nitric acid as silver.

[@G2Gltd]
