Congrats on the new rig! Fantastic! Its awesome that you keep getting better while still maintaining the Mr Sreetips vibe. I cannot say enough good things about this channel. One Decillion applauds!
Would love if you did a “Lessons Learned” segment after you weighed it out - not only this video but others in the past. An example would be - talking about this process vs the process you used in the past. Did you use less nitric acid?, do feel it was worth it?, clean-up time vs in the past. Doesn’t have to be long, just a couple of minutes
You are welcome. Nice to see the fancy glassware being utilized at the service! It’s function AND Fashion facilitating a result that is functional and fashionable. Thank you Sir!👍👍🤟
Nice set up Kevin. I like the reduction in fumes. Appears that you use perhaps half of the nitric acid you have used in the past for this amount of material. Outcome is beautiful as always. Thanks for sharing!
Good to see this reflux set up Sreetips. Less waste and better for the neighbourhood. If you want to work faster, Q-glass make quartz boiling flasks (China suppliers also have them). The advantage over borosilicate glass is that they are near impossible to break with thermal shock. You could dunk them red hot into ice water and nothing happens. The number is something like 1000˚ per second decrease or increase in temperature and not crack. Borosilicate glass is about 160˚, bottle glass, 60˚, ceramic 30˚ or so, from memory. Also, lubricate joints a drop of conc. H2SO4 so they don't stick. I'm pretty sure you could melt the gold sponge in quartz glassware and have them survive. But $400 vs $40.
I've watched you for over 2 years. This process never cease to amaze me. I make award winning wine. It's very good. Today after 2 years it hit me like a slap to my head. I use potassium metabisulfates to kill off residual yeast before I bottle. Wow. We drink that stuff. It keeps our bottles from blowing up. Yeast tends to hibernate lol. I had to look at my chemistry shelf. Yes I have a large bottle of it. ❤😂😂😂😂
Yup, sulfites in many forms are used, some nitrite and nitrade as well. The potassium ion part will not affect with this reaction, just a bit more expensive , but it is the sulfade form that is incorrect. SMB is sodium metabisulfite, since only the sulfites generate SO2 (sulfur dioxide) that drops the gold out of solution. Just sodium sulfite will work almost as well (less sulfites by half), you can't get that at a garden shop (Stump Out) though, and most times it can be expensive in some areas, mostly used in photography development.
We like the tastes we get from the past. Another way to kill the yeast is an oxidizing agent like silver, pure elemental silver, buy a bit from Kevin, maybe one of his small vials and test the efficacy and taste on a bottle of your best over the years of aging both corked and open with no closure. Some monks used to decant into small silver casks and after a time, re cork a bottle to age. You may have heard about them, the Benedictines in the mountains of Spain. Value added indeed. Edited for typos.
@CothranMike I used 2 10$ gold pieces to kill a bacteria that my Camden tablets (sulfates) couldnt kill. Last resort. It actually worked. Saved a chokecherry wine.
Your setup looks awesome! The new burner with stir bar support in particular look perfect for what you're doing. It seemed to work very well. Great video! 👍
I LOVE to see the upgrades, Mr. Sreetips! It's awesome to see you constantly doing your best to learn and improve your process and equipment! I hope to follow your example soon.
Holy smokes mr sreetips this bar is awesome man wow single refining is great! Keep it up mr Sreetips your processes are great 🎉greetings from the Netherlands
Arielle, I didn’t pay close attention to that because I was trying it for the first time with gold. I’ll do another video and use the new setup, and the old method and measure everything to see the difference.
That's a nice elegant setup , it at the very least makes the fume hood exhaust less unpleasant , nitrogen dioxide is unpleasant in tiny concentrations , and Nitric is one of the major expenses recycling the water from the acid as another positive as you get less corrosion from the acid concentration on the condensed fumes on your ventilation
I see one improvement to make: Fill the condenser from the top with cold water, not from the bottom, so you can use the counter flow for improved thermal transfer efficiency.
The purpose of doing refining in new enclosed container is to show variation to the normal process and to save on Nitric acid by condensing the fumes. It would have been better if you informed us how much Nitric was used this time and how much Nitric you use normally (you know as a thumb rule). Because not every one is fortunate like you to be able to procure Nitric acid at such lower prices and in such abundance. It would have inspired those unfortunate few to shift to this kind of enclosed set up. Over all an excellent video as usual. I learned a lot about gold markets, processing etc from you.
Excellent. I was focused on the setup and operation, working the bugs out. I didn’t pay much attention to nitric efficiency. Maybe I’ll try another batch split in half, one half to the new redux setup and the other to the old way.
@@sreetips Silicon grease can leave contamination in the appearances for the shine surface of your gold, use sulfuric acid instead, works as well at the temps you work and will allow separation without any contamination. One drop or two on the ground surface is enough, apply to stopper rather than the inside neck, although, your usage would work either way, a bit of a twist to distribute and you are, err, golden, sorry for the pun.
Awesome video 😊 the money i spent on that setup was worth every dollar!!! Still on the same radon fan for the last six months in my fume hood as well !!! Silver is almost worth digesting with this method by it self !!! Remember its about percentages if your trying to turn a profit 😊
Thats what I was thinking, too. Looked like quite a "poof" of the mud went into the gold waste jug - the quick glimpse I saw of that jug after looked like there was at least some solids. That and the set-aside might account for most of the discrepancy.
@@GigsTaggart More than a few milligrams, I'd say somewhere between 500 and 750 mg as my best guess. And let's not forget the inevitable loss to the silver jar as nitric alone will dissolve gold, just very slowly and in small amounts, the remainder is most likely the lower carat.
NO2 will be generated by this reaction, the more uncontrolled this reaction is allowed to run, the more will be created. By slowly adding the nitric acid you control the reaction much better than if you dump in large amounts at one time - it only takes longer. I think the point of the reflux condensor is a different one: You will have water vapor condensing on the cooler and the NO2 will react with this water to nitric acid which then drops back into the reaction. Basically you are recycling your acid until it reacts (to some point you will loose NO2 as a gas). This can be seen in the reaction funnel where some nitrous gas escape via the pressure compensation tube and is dissolved in the nitric acid.
Hello Mrs and Mr Sreetips. I love this goldrifinings clip🔥I never get bored🌺So thank you Sir .Have a cosy weekend. A big thanks to Mrs Sreetips..83 gram 18 karat..100 bucks😂 God bless you🙏
More than likely it was... some folks like to get away from wood, steel, brass (if so, good! It is nasty stuff, zinc and tin can mess you up in the long time, users), aluminum and such. Glass is easy to clean as well. Fused quartz burner bowls, while expensive, are best. Edited to add punctuation for clarity.
Impressive, but I still like it when you use the gas generator to extract the gold. However, it's nice to see you trying out new toys. Keep up the good work.
I don't know what it is about the texture/pattern of the ingots but they look way better than a 1oz pamp suisse bar. I think I like the random patterns better than a boring perfect bar.
I'm not sure if you are saving the rest of that gold for other videos, but you should know that larger volume in refining means greater efficiency. The amount of energy costs, will greatly reduce when you are doing one batch instead of 2 or 3. Your reflux vessel and other equipment could easily handle a much larger batch. Efficiency wise, it would make more sense to do larger batches.
He is extremely efficient. He may well have poured a good amount off into the gold refining waste container, but it's not waste - this man does not use the term waste like most people do because he simply doesn't waste. I've been binge watching him the past month, and believe you me, be it gold, silver, even copper that he uses to cement out silver, he recovers what is practicable (plus some). He does volumes he's comfortable with which I say should be respected
@@m8imhawk Product loss isn't the issue. That can always be recovered later. I'm saying from the point of product unit/energy it's more efficient to do larger batches. Certainly from a product unit/time perspective this is also true. I love all his videos and will watch everything he makes.
@@sreetips oh, no, say it isn't true! Maybe slow down, post once a month, same format, either silver or gold, refining or harvesting, the occasional index to prior videos, and if you see one you haven't done to your satisfaction think about redoing that video maybe. You know, just to keep your fingers in, so to speak. I know you'll lose momentum if it's not once a week but at the rate you've been going it's been more than once a week maybe even sometimes as many as three a week so slow down if you want.
@@sreetips well, if you need us to say take a vacation, take a long one, enjoy the world as you wish... but take your kit with you, no, seriously, leave it all behind. Brigadoon is calling!
The nitric reacts with silver and copper to form silver nitrate and copper nitrate. I don’t know how to recover the nitric from those reactions. And I wouldn’t even if I knew how. I have access to plenty of nitric for my refining.
You could with a little plumbing recycle the used acid by recondensing the used nitric into the " liquid" for the nitric boils , it's basically strong nitric acid that's condensed from the reaction and should have very low contamination , it would also decrease the waste "silver jar liquid volume" we used to do this with solvents to make "gunwash " , excellent video by the way , love the attention to detail in the process chemistry ,
Give that addition funnel some support on that angle with a stand, during the refluxing. Take some weight off the glass seal and good idea to help secure addition funnel containing strong acids like HNO3. Protect the equipment and yourself some more.
The color off of Nitric Acid Boil #1 was much more intense green!!! Was it from your new set up or just the composition of the base metals? Not sure but that gold looked flawless after just one refinement!! I’m no scientist (I’m just a subscriber drinking a beer right now) but I think your new set up is definitely making a more pure product! Keep up the great job!!
The composition of the base metals, as a best guess I'd say there was more than the usual amount of palladium in there, probably from the dental scrap.
There was some dental scrap in this batch. Usually the solution is blue from the copper in the sterling that I added. Dental scrap contains platinum group metals. Those metals in solution appear yellow. Blue plus yellow makes green.
I’d be curious to know your total cost involved with these processes versus final value of refined metals. Cost to obtain the metals, cost of chemicals used during refining, etc.
My wife bought 7.5 pounds of unmarked silver at an estate sale a couple weeks ago for sixty five bucks. That’s a hundred ounces of silver. Chemicals were probably a hundred bucks. But really, none of that matters. I’d have to sell to realize a profit. And I’m not wanting to sell any of my silver.
rotate the rubber tipped bar on the support stand with the thumb screw so the thumb screw faces the front, so you dont have to reach around every time.
May have mentioned previously that I personally prefer silver to gold. I say that to say this: watching that silver melt away into the gold is heart-wrenching. 👀😁
Dear heart-wretched, fear not, I recover the silver and run it through my electrolytic silver cell and convert it to three nines fine pure silver crystal.
Here’s an an alternate plan: the sterling contains a known quantity of silver so long as it’s not melted and the markings ruined. Hold the sterling silver as is. No need to refine it. The only reason I refine it is because I use it to refine gold.
dam the reflux setup is real fancy. the spherical kevlar burner/heater was a treat. why care about nitric efficiency when you just boil it off later when you evaporate down? are you just low on nitric? i mean i appreciate the reflux setup
Did you notice that I did NOT have to “evaporate down” on this refine? That’s because I added just the exact (almost) right amount of nitric to dissolve the gold.
Interesting! Was wanting to see if there was any reaction in your nitric waste jar, but I didn't see any silver in the jar or fumes coming out! Do you think you consumed less nitric acid or got more mileage out of it?
@@sreetips You certainly reduced the amount of nitric required. There was enough of it dripping down from the condenser. And I am willing to bet the manual of that condenser instructs you to have the cold water enter from the top.
What happens with all the zinc? Its 10% of brass and I watched your waste stock pot video and see you cement copper but I have never seen you process the zinc?
It’s nice to see your new setup. Hopefully it produces some higher yields. If not then then hopefully it makes the process a bit easier for you. Either way, I enjoyed watching this process
@ that’s awesome 😎 it’s efficient and looks cool. Maybe you can add salt to the ice in the bucket with the pump to lower the temp of the water cycling through the condenser column. But I’m not sure if that’s cost effective
This looks like something that might be done with a Soxhlet extractor if the condensate can be sufficiently acidic. The efficiency could be greater as the enquarted gold would contact only warm, pure solvent.
Yo can go as high as 33% (8k gold) but it takes longer and uses more acid to get everything out of the gold. But I could do an experiment with the new setup to see.
Maybe you could do a cleanup video? By which I mean explain the process of recovering the glassware after the processing where the beakers get stained etc.
Man it'd be nice to have quick release on your stand that holds your neck and everything but I don't know how tight and secure quick releases can be unless they're adjustable ohh man how much time do you spend spinning a wing haha
Dear Mr Sreetp, I hope one day you display your laboratory equipment, instruments, and devices, such as flasks, crucibles, etc., and everything found in the laboratory, then explain the benefit of each one.
Reflux addition was a real treat to watch and learn. I hope we will see this technique in future vids. Thanks and say hello to Mrs Sreetips

WoW Shreetips, that's a lot of equipment on the table. LOOKS COOL.🙂🍁
The little bit of gold that was left over that you put off to the side that's probably the remainder of the yield you were looking for
Thats what I was thinking, too. Looked like quite a "poof" of the mud went into the gold waste jug - the quick glimpse I saw of that jug after looked like there was at least some solids. That and the set-aside might account for most of the discrepancy.
Both those put together were a few milligrams. What he said was probably right, some was just lower karat

Did you notice that I did NOT have to “evaporate down” on this refine? That’s because I added just the exact (almost) right amount of nitric to dissolve the gold.
Interesting! Was wanting to see if there was any reaction in your nitric waste jar, but I didn't see any silver in the jar or fumes coming out! Do you think you consumed less nitric acid or got more mileage out of it?
Yes
Great work. Looks like you have another refining method in your arsenal. Looks pretty efficient too.
I think it may have reduced the amount of nitric required
@@sreetips You certainly reduced the amount of nitric required. There was enough of it dripping down from the condenser. And I am willing to bet the manual of that condenser instructs you to have the cold water enter from the top.
What happens with all the zinc? Its 10% of brass and I watched your waste stock pot video and see you cement copper but I have never seen you process the zinc?
Because it is (nearly) pure copper, not brass.
I love to see new toys in use.
Nice mantle! What kind of vacuum grease are you using?
It comes on a white container about the size of a silver dollar.
I use Dow Corning. It's expensive but holds up to fuming nitric acid 😉
It’s nice to see your new setup. Hopefully it produces some higher yields. If not then then hopefully it makes the process a bit easier for you. Either way, I enjoyed watching this process
It saved on nitric, and it’s better than shooting those fumes up the stack.
@ that’s awesome 😎 it’s efficient and looks cool. Maybe you can add salt to the ice in the bucket with the pump to lower the temp of the water cycling through the condenser column. But I’m not sure if that’s cost effective
Amazing bar
This looks like something that might be done with a Soxhlet extractor if the condensate can be sufficiently acidic.
The efficiency could be greater as the enquarted gold would contact only warm, pure solvent.
Great idea! and way to conserve Nitric. Very nice! I'll bet you could make a good Bourbon 🙂
The King of Inquartation
If you flip your clamps the adjustment will be on your side of the fume cupboard.
I know, I realized this during editing.
If you felt like it, you could bubble the brown NO2 gas through 20% hydrogen peroxide and recover nitric acid.
Nice!
Hey Kevin, have you ever tried to use less Silver for inquartation to save nitric acid? Excellent video. 👍
Yo can go as high as 33% (8k gold) but it takes longer and uses more acid to get everything out of the gold. But I could do an experiment with the new setup to see.
Love your work ❤
Great video- never gets old
Always enjoy watching
Maybe you could do a cleanup video? By which I mean explain the process of recovering the glassware after the processing where the beakers get stained etc.
Since most of the solutions are acidic, there’s no stains, usually
Nice upgrade!
Good score there Mr Sreetips
Was it more HNO3 efficient than beaker boiling?
I think so, but I didn’t measure anything. Was just getting the feel of using my new setup.
Man it'd be nice to have quick release on your stand that holds your neck and everything but I don't know how tight and secure quick releases can be unless they're adjustable ohh man how much time do you spend spinning a wing haha
Due to inexperience I hand the thumb screws on the clamps facing toward the rear instead of toward me.
You can make your own nitric acid with that new rig you have. Shows you how right here on TH-cam
I know. I’ve seen it. But the process is cumbersome. I have access to plenty of nitric acid. Thankfully, I don’t have to make it myself.
That bar is a thing of Beauty and nice ripples as well be safe everyone
Dear Mr Sreetp, I hope one day you display your laboratory equipment, instruments, and devices, such as flasks, crucibles, etc., and everything found in the laboratory, then explain the benefit of each one.
