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. 👍
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 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.
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.
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.
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...
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...
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.
@@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. 👍👍
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 😁
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❤
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.
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!
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!
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... 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?
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
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,
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
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 ?
@@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 🙂
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, 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.
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.
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.
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
@@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.
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.
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.

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 ?

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.
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
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.
Two questions: How much all the acids used here are worth & how big is the ammount of waste acids produced here?
mate absolutely awesome, but what type of ammonia do you use?
Regular household stuff 🙂
Which type of ammonia?
Can you do a video of just beauty shots of gold nuggets and bars? HD/good cameras/lighting/smooth slow rotation
Do we need rinse the gold by H2SO4 after precipitation? Thanks Sir
Very cool
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✌️

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.
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.
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!
What’s the purity of the hydrochloric acid you use to make aqua Regia?

Hi from Tic Tok😉
Hey! Thanks for joining me here!!! 😁
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.
When I check copper karat. Copper show 5 karate. So can I refine this 5 karate form copper please
Can this method work in PGMs. Specifically palladium and platinum
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
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.
Shouldve used a magnet for the sand... :) love your videos!
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.
Respected Sir If 1kg Gold Dore Has 83.33% of Gold and remaining 15.67 other Metals Then after Refining Can we Make it as 1kg Pure 9999 Gold..?
If you remove 15.67% the weight will decrease by that much. You can't turn base metals into gold if that's what you're asking.
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.
