The Bob Ross of gold refinement. Love your videos.
Thanks, Ethan! I'll take that comparison any day!! 😁
Sodium metaby sulphate?
Sodium hydroxide ? Use
Any one?
I though his voice had a Jack Nicholson quality.
Lol .. yeah a combo of Ross and Nicholson... Just needs a few swear words lol
if someone told me... "when you grow up you will spend hours watching videos of guys refining precious metals" I never would have believed it... here I am watching you and sreetips all the time
I someone would have told me I'd have the opportunity to do this stuff and then share it with the world... I would of hardly believed it myself. I very much appreciate you watching.
Can’t get enough of your videos Jeff ,keep ‘em coming
Great to hear! Thanks so much Chris!
Came over from tiktok - really love your content - like honestly 10/10.
The subject matter is interesting, your knowledge and skill is obvious, you communicate what you're doing well and have a voice that's genuinely nice to listen to! Oh and of course the vids are visually stunning!
Thanks for joining me here as well George! Thanks for the wonderful feedback... im glad these vids speak to you!
Good video Jeff. First time I have seen the ammonia rinses and it looked like it really cleaned the gold sponge.
I'll tell ya, that ammonia has been a game changer for me. It really scrubs out that sponge. I appreciate you watching John!
Same here, i never knew about the ammonia rinses , so Jeff tell me , you buy the ammonia in form of what? Liquid ?
i think you still shoulda used distilled water at 4:45 because yes even though tap water contains trace amounts of chlorine, the hydrochloric acid is like half chlorine, so you dont need to add extra chlorine into the system, if anything tap water would actually contaminate your gold solution, adding more to wash out when you percipitate it. also, you shoulda added a small amount of sulfuric acid to percipitate any lead that would naturally exist in the metal, cause its definitly there because it came from a natural source and not like jewlery or bullion.
I found the pros out weigh the cons at that point. Distilled water doesn't always flush that remaining silver out of the AR like my filtered tap water does. The deposits it might carry are washed out later, easier than the silver still in solution would have. It's working for me!
Oh yeah, always have to add the sulfuric acid. Bummer I didn't include it in the vid!
Thanks for watching!
@@LithicMetals yeah makes sense tbh. im just used to using distilled water for everything cause thats what you'd do in a lab setting, because sometimes things can be pretty sensitive to tap water (especially if your trying to get high purity products). also its even more so important to add sulfuric acid to natural specimins, as they contain higher lead content than most scrap gold.
I enjoy watching both you and sreetips refine gold.
Thanks Jeff. We deal with a lot or raw gold and dore bars made of electrum (Au 60%, Ag 40% plus traces of Cu and Pd). We sell it at 40% discount to the 100% pure gold. However i'd like to experiment with this process as people dont like "contaminated" bars. Great explanation.Very easy to follow and in your voice not some weird computer voice reading a script. 👍
That was so awesome! So much more professional than the way I've been doing it! Thanks for that!!
Thanks for the props Matt! 😁
Hello Jeff. Thank you fore this Great clip🙂. Take care, and God bless you.
Thanks for watching!
Very good explanation of what you were doing within that process. Nice outcome.👍
Love your videos. Really cool to watch the whole process
Great to hear, thanks Jacob! 😁
Jeff right on Brother thanks alot that was awesome man see ya from Alaska 🎉🎉😊
Good stuff bro, loved it. The ammonia rinse also dissolves any organic gunk passed on onto the metal.
Dissolving the SmB in water first allows you to just pour it in and get perfect mixing and an almost instant crashing out of solution of the gold. Cool to see.
Love the videos. Brand new to the industry and these teach me a lot!
Great to hear Collin, thanks! 😁
New to the channel...bravo love this video, can't wait to watch my way through the back catalogue. Informative and something for me personally to aspire to 👏
I appreciate you joining me here! I hope you enjoy the other vids too! 😁
That was awesome Jeff! Thanks for sharing👊🏻😁
Glad you enjoyed it Derek! Appreciate ya watching!!
Love your vids, Jeff. So silky smooth! The look of that gold solution always amazes me! ❤🤩
Wonderful to hear. Thanks for saying so!! 😁
Why isnt it the practice to kind of compress or adjitate the balls floating at the bottom, like at 3:28 it looks like the liquid is getting into the balls, and that you want that to happen, would something like a masher help break it up making more area covered by liquid?
Honesly id never do this or anything, just a question, this process seems so wild, real life gold out of sand haha
Great job Sir! I can’t wait! 👍😁🤗
Hi Jeff, I really enjoy watching your videos, keep up the great work
I really appreciate hearing that, thank you!
Thank you Jeff🌹🇳🇴🇺🇲
You can eliminate the chloride steps by simply continuing to boil in AR until the solution remains colorless. A touch of sulfuric acid during digestion will precipitate any lead. If you do this it will reduce the quantity of waste solution as well as the number of chemicals that have to be purchased and dealt with in the waste stream.
If you watch the video give a like , he is sharing something not a lot of ppl understand 👍
Thanks, Scott. I appreciate the support! 😁
I include ammonia boils that I learned from your videos to part of my rinsing protocol. It makes the finished piece have a mirror finish!
I'm glad! Just don't pour the ammonia waste into your stock pot
I love the idea of "fresh" gold. Just picked!
💛
Watching gold being refined never gets old.
💛
Here in Brazil, I use nitric acid for treatment and ammonia, ammonia to remove chlorides.
1:40 I would have used the magnet before the fusion to remove the magnetite, (black sand) if present.
I am amazed how much it takes to purify gold!! It is kind of mind boggling! 😅
Hi Jeff, I have see, you are doing ammonia rinces and gold looks amazing. I have some 3+ g of placer gold I washed myself, I clean it very carefully, that is the best part of prospecting. Here (CZ) is placer gold 22 K+, very goldy, mostly with silver, not much copper if any. One of reasons, I am watching refining videos, not to loose MY gold in refining process...
Thanks for watching! I hope I offer you a few good tips!!
@@LithicMetals Yes, you realy do, but not few.... many... 🌟🌟🌟🌟🌟 😀
Hi Jeff
Great work but I did not see any denoxing at all with Urea or Sulfamic acid can you please comment on it.
Thank you
I generally don't use excess nitric, so denoxing isn't necessary. However, I generally evaporate the solution once or twice to burn off the small amounts left over just in case.
@LithicMetals got it
Thank you so much
That ammonium you mentioned, is it ammonium sulfate?
ammonium hydroxide
That is liquid friend?@@Robert-bt8yj
Very professional job.
Thanks! Appreciate you watching!! 😁
You're a wonderful man. Exactly I have deposits of quartz almost similar to the soil I worked on I don't know man is it like it or not until I do like you ... Was this yellow dust caused by concentrating rocks and washing? thank you you are wonderful❤
Thanks so much for sharing!
Thanks for watching! 😁
Hello Jeff. Hoping you an your famely are fine.🌹 Seeing forward to more clip from your Great canal🌹. Arne from Norway 🇳🇴
This is such good stuff here!! I pan gold and have accumulated 50 grams so far. I bought it all from Klesh over the past couple of years and I dream of the day I can do exactly this to my gold. Thanks for showing me how! Now I just to get your setup in a shop… Hey, will you sell the equipment and chemicals or provide a link with a code so you get a commission?
Hello Sir, thank you for educating us, can i know if you loose the other precious metals and how much gold you loose in the process. And do you think if i have liquid gold in my suitcase the x-ray can detect it ?
You don't lose anything in the process. Yes the xray would see it. The last thing you'd want to do is carry liquid acid around.
Jeff HAS TO BE sreetips son. Theres no way they are NOT related!
Lol, I'm pretty sure we're about the same age.
I heard Sreetips mention the reason he doesn’t use cement silver for enquarting is because other metals will follow the silver when rinsed out, thus contaminating the cement silver again. I guess if you’re not dealing with silver it wouldn’t matter though.
Edit: the one he said follows silver the most begins with a P, wasn’t platinum though. Can’t remember the word right now.
None of that would really matter much because when I recover the silver, it will go to the silver cell to be refined anyway. 🙂
@@LithicMetals oh you refine silver also? Haven’t seen any videos of yours about silver yet. I’ll go look for that! New subscriber and I’m loving your content! Appreciate ya! 💪💪👍
@@LithicMetals oh and I guess Sreetips would have gotten the cement silver from refining the crystals out of his silver cell, so it makes sense for him not to want to recontaminate it. Different strokes for different folks. 👍👍
Hello Jeff, today I for the first time refined some silver using cupellation process. Small test, turned 2 g of 800 into 1,580 g of pure (I hope) silver, that went great. Also tried to refine 2,5 g of 585 (14k) gold, it turned it into 636... I probably eliminated just some 200 mg of base metals. I must clean the bead from cupel and oxides residues (sadly no sulfuric, I will try pH minus - NaHSO4), inquart and go with nitric or not inquart and go with HCl + H2O2, or directly AR... I am nor sure yet...
Sounds like fun experiments! If you really want the gold to be pure, you're going to have to inquart it.
Hello... Thank you for the most inspiring vids. But I have somw questions... You used ammonia to rinsed the gold powder? what type of ammonia? the one from the hardware store?
I'm glad you enjoyed it!
Correct, just household ammonia.
@@LithicMetals Thank you so much!!!
Hello Jeff. Always a highlite
Peace be upon you, I added nitric acid to the silver and after it dissolved in the solution I precipitated it with table salt, then caustic soda and sugar, and I washed it more than five or six times and heated it until it returned to like four, and after and after I went to melt it, I noticed that when melting the graduation material, and when I put it in water it returns to being like dirt and the rest is black in color and I hold it in my hand and it disintegrates??? What is the problem? Please advise us,
Very clean precise workmanship great job👍
Thanks so much! I appreciate you watching!! 😁
Man that is a lot of work for 7 grams of Gold
I'm glad I'm not the only one who thinks that lol still love the vids though
How many times can the acids for the rinses be reused? The Aqua Regia can't, but the others I suppose can be used a few times, as I imagine they aren't cheap.
When everything is done right, you can't reuse the reagents because they are spent.
@@LithicMetals Thanks for the info!
Why did we put water before acid, are we not making the acid weak????? Which I think might slow up the proces
As a rule of thumb, you shouldn't pour water into the acid. Always start with the water first. The water gives the metals a place to go. Yes, it slows down the reaction. But you generally want that control vs a reaction that runs out of control
Your video's are so inspiring, great video mate.
Thanks so much! I appreciate hearing that. 😁
What’s the purity of the hydrochloric acid you use to make aqua Regia?
Two questions: How much all the acids used here are worth & how big is the ammount of waste acids produced here?
For real, id like to meet the person who figured all this shit out
Fabulous work 🎉
Thanks Danny! I appreciate you watching!! 😁
That was awesome tq for sharing😊✌
💛
I'm familiar with refining, but would like to use the ammonia rinse. Any particular kind or % to look for? Thanks, love your content!
Do we need rinse the gold by H2SO4 after precipitation? Thanks Sir
Can you do a video of just beauty shots of gold nuggets and bars? HD/good cameras/lighting/smooth slow rotation
When I check copper karat. Copper show 5 karate. So can I refine this 5 karate form copper please
What is the that white bake pan you use? I bought some at Walmart but they explode when I heat them up on the hot plate.
Yeah, you can't use most glassware on a stove top. I use the old school Corningware dishes.
Alright got me a few on eBay!
They’re slightly pricey but they should last me for a long time.
Sir good day, I would like to ask you a question about neutralizing/denoxing the nitric ions, why is it that after the filtration i made from aqua regia gold solution, why there's white powder/ white silts forming from the bottom after I added Urea 46-0-0 and sodium metabisulfite to the solution.
What's the next step should I do to precipitate the gold?
Hmm... did the gold drop out and settle, and then a white precipitate settled on top of it? If so, I imagine you used a bit too much SMB.
Or do you mean that you added the Urea and SMB, and no gold dropped out and the white precipitate formed? If that's the case I imagine you may still have way too much nitric in the solution. In that case I'd either add and dissolve more gold until the nitrates are spent, or keep boiling off the solution and adding more hcl until you're confident the nitrates are used up.
@@LithicMetals thank you so much sir, noted.
Great and clean work, you deserve to be an expert teacher. If you give me a recipe in a comment written in full on how to purify brown and yellow gold dust and alternatives to the dissolving and dissolving liquids until the end of the smelting, thank you. I am waiting for the response from every expert. I love everyone.
It's not something that I can teach you in the comments section. If you really want to learn, you'll have to put in the effort and acquire the knowledge.
@@LithicMetals But I know how to find gold ores in the passage stones, quartz, valleys, and types of black, brown, and yellow gold, and I know how to heat the stones, grind them, and filter them from the soil with water to keep the heavy metals such as gold, silver, and iron, and the method of isolating iron and silver with hydraulic acid or by roasting with activated charcoal to evaporate the oxides and filtering several times and drying. I just want more clarification if you are satisfied with that, and thank you for the advice
hey so i hope this isn’t a dumb question too ask but i enjoy your videos a lot and was wondering if Precious Metal Refining is something someone can do as a hobby for people ? like would i need licenses for anything like the equipment or chemicals ? Thanks again man :)
You want to check your local laws, but yes... I started doing it as a hobby. There is a lot to learn in order to do it safely. Go to the goldrefiningforum.com and start reading up!
@@LithicMetals Thank you man i appreciate it :) !
Great video, good job brother🤜🤛
Thank you Loren! I appreciate it my man!!
Anytime I hear "I'm Jeff"
Fascinating!
Love the content.
Thanks, Lance! I appreciate you watching!! 😁
Love this content.
Wonderful to hear! 💛
Did you go to school for this? Have a degree in chemistry? Self taught? What's your background that allows you the smarts for this? I love listening to and watching your videos. I'm a silver artist and thought about refining my own used silver.
I first read a book by CM Hoke, she essentially wrote the refiners bible in 1940. After going through the experiments she outlined and with the help of the goldrefiningforum community, I picked up a few things. I've had gold fever since I was a kid, and I think playing with gold was just inevitable lol 😁
Most people use a magnet to trap the black sand and collect the gold from the pan or container.
👍
Another great video 🙏
Thanks David! 😁
When you add ice, is it fromdemineralized water?
Hey, Chris. No, I use plain filtered tap water for the ice. At that point, the solution is quite free of silver. If there is silver left in the solution, the traces of chlorine would cause it to drop out of solution, and I can then filter it out before proceeding.
Nice video 👍
That's so much time, energy and resources for about $400 of gold.
👍
Do put it on the stove.?
Do you sell gold as powder? Like in 12:00
Not often. 🙂
Can this method work in PGMs. Specifically palladium and platinum
Which equipment do i need to have this lab?
The most important thing would be a fume booth. Then there's beakers, hot plates, buchner funnels, PYREX dishes, melt dishes, torches, quantitative filters, scales, an assortment of chemicals, and a dozen or odds and ends.
Mighty fine 🎉
Wow. just wow 😊
Interested in your venting procedure
Do you mean my fume booth? I designed and built it.
@@LithicMetals both ur fume hood and where/how you vent it.
What's the chemical composition for smb
If we use SO2 for prepicitation. How is the Purity of gold if compare with SMB? Thanks
If everything is done right, both methods should yield 3nines or better.
mate absolutely awesome, but what type of ammonia do you use?
Regular household stuff 🙂
Which type of ammonia?
Hi, thanks for the video.. I am wondering on how to go about the SMB part... how do someone know the ratio to use, or approximate the amount to use?
If you have all of the free nitrates used up, you'll need just under 1g of smb for every gram of gold in solution. 🙂
@@LithicMetalsbagaimana cara mengilangkan nitrat bebas yg anda maksudkan?
Love your vids!
saw you first in TT.
where did you learn to do this stuff?
if you dont mind me asking.
Thanks! I started by reading a book by CM Hoke, then I just researched everything I could.
Sweet dude! I’m using Shor’s kit for two pounds gold plated copper contacts this week. I’m not liking the results. Wish I had extra time and stuff to get pure like you man!!!👍
I have a pound of their Quadratic Precipitant that I'm excited to use one of these days. I suspect that their kit should do the trick for ya, hope it goes good!
Great job....really enjoyed your presentation....very knowledgeable, and thank you for sharing....
Bill
My pleasure Bill! Thanks for tuning in! I'm glad you enjoyed it 😁
Professor, he has soil containing 2%. First, I conducted roasting, then washed with HCL, then nitric, then regia, but he did not eat the gold. There is a barrier that separates gold. Can you give me a way how to get rid of a barrier so that royal water dissolves gold
Melt it back down and inquart the gold. Then start again with nitric until all base metals dissolved. Then aqua regia.
@@LithicMetals Yes, I performed this operation, but the gold did not dissolve. There is a crust. I did not know that this crust is what prevents the gold from being dissolved in royal water.
@@LithicMetals What do you advise me to do so that my royal water breaks a barrier and eats gold
What do you do with the leftover chemical solutions?
There's a series of simple but time-consuming processes that render it all inert. I'll probably do a vid or two on it.
From where could i get the Ammonia ?
Anywhere, really. Grocery stores have it near the cleaning supplies
Why is the gold that precipitates brown and not gold colored?
I don't know why it absorbs light differently in that state. It's a good question to answer. Wish I could.
@@LithicMetals When you grind down white powders they often turn black (titanium oxide, a white paint pigment for example) because the light is difracted instead of reflected back to you. I assume that the fine gold sponge is full of molecular sized voids which will absorb and scatter light so it darkens. As soon as it melts those voids go away and the light is mostly reflected back at you again.
How much gold in one Bitcoin?
Can you add the ammonia waste to a regular stock pot?
No, it's not the best idea. I store and treat it separately. 😁
Hoping that life is treating you well and hope to get some new material from you soon...
I appreciate it. I have a lot of footage to edit, I've just been too busy in the lab to post vids. But I'll have some great pours to show you soon!

Good to hear & I can't wait!!!
Hey, there has to be some book to learn how to do this process.
I started by reading CM Hoke's book.
Do you use tap water ice cubes or distilled water ice cubes
I use store bought ice at that point, which I consider to be tap water.
Cool Jeff ,I was just wondering how much the loss would be on 20 grams 10 k .now I know maybe around 3 g? I follow stree tips as well. Cheers man✌️
20g of 10k = apx 8.33g of pure gold. I appreciate you following me as well!! 😁
@@LithicMetals looking forward to your next big project and it would have been great to have picked up one of your pieces.
@@jennc8554 I'm just about to wrap up my first 1/10oz Mercury series. A total of 250 pieces in the series. I have two on my bench at the moment. If you'd like to see pics or more info, please feel free to email me at lithicmetals@gmail.com 🙂
Hello teacher I'm doing the same thing as you in Korea. It comes out 99.9% in winter and as the weather gets hot, I see silver. I think it's because of silver chloride. If I pour tap water before filtering the filter, can I filter 100% of silver chloride due to chlorine?
The chlorides in my local tap water will precipitate silver chlorides, but the real key is to dilute the AR. At least double the volume. It also helps to filter in a Buchner funnel with a vacuum. The pressure difference also helps to drop out Ag from the solution.
@@LithicMetals Teacher, what is AR?? And would lowering the temperature of the royal water help?
@@LithicMetals Teacher, I'm waiting for your answer
AR is Aqua Regia
