That's a righteous button of 999 fine gold, sreetips! I'm digging this stockpot series, it's packed with very valuable information for we who are following in your footsteps. I can't wait to see the PMG'S being separated from the solutions and melted up!
I am actually happy that you decided to do the SMB route, I had replied to another persons comment on the part 3 section where they were asking how you would go about refining the SMB solution and it appears that you are going to do something like that. it just makes sense as once you get the gold out its pretty straight forward with what you've done in the past. Great work as usual!
Absolutely brilliant work sreetips ! This video is like your products - Pure Gold ! The spot plate tests are beautiful. Looking forward to episodes 5,6,7,8 and hopefully more :)
Thanks aga. I had to take the day off. Been staying up late and getting up early and it finally caught up with me. Just as well because that solution with the SMB added needs to settle completely. I'll hit part five early tomorrow morning.
Fantastic video series. The logic and thought process is a delight to see. For me, Hoke's book on gold waste procesing is a great resource but putting it to practice was difficult without pictures let alone video showing the reactions.. Your video and comments are excellent in visualizing many of the steps. Hoke (she) is probably over your shoulder looking down on your work . Additionally my chemistry experiments have been generating more waste that require processing. I plan to use your process. Thank you for bringing us into your lab. .
That was fun to watch the 7.9 gram gold button come out of part of this, process I'm already very excited for part 5!!! Thank you, I'm soaking it all in and loving it!!!
My first comment would not post, so here is another: Fantastic formulas! Great results too! 7.9g is not shabby! I can't wait to see the yields when you drop the platinum and the palladium! I'm also very curious about whether there is rhodium, how you would test for it, and what the quantity willbe if you try to extract it. This has been an awesome success so far! You might be getting good at this! LOL Thanx for an awesome series buddy! :D
Wow I am so excited for the rest. Can't wait to see how much gold persipitates out of the solution. Then to see how much u get of palladium an stuff. Excited thanks for being a great teacher.
sreetips, not sure if you will read this but, I use plastic syringes to remove solutions from precipitates. It's much easier and faster than a pipette. They are cheep, easy to clean, and last a very long time. Just extend the tip with some tubing. They also work great to start a siphon, just hook up the tube, pull on the syringe a bit and pull off the hose.
@@RobertSzasz in my public school we played with sodium metal, teacher said "i know i know im not supposed to know this , Slade i need your knife for a minute and you can get it back at the end of class, but were gonna have fun today!"
Great sir . I was accepting little bit more gold by seeing the volume of solution when u started this video but great and very egearly waiting for next part thanks for sharing sir
Great job sreetips! That 7.9 gram bead came from the incinerate leftovers. I'm curious how much gold you got from the big flask at the end of Part 4? With all the great videos you have done, how are you going to top this? :)
All of that fine gold floating on top at about 12:40...from my experience placer (and hardrock) mining, a drop of dish soap will make that drop to the bottom in an instant. Not sure how dish soap reacts with those acids. Might want to try first.
Shouldnt you rinse with water to rid the nitrites before rinsing with hcl? If nitrites are there its liable to dissolve some of your gold and loose it before precipitating.
You and your video's have been a great help. I understand why you re-dissolve the gold to clean and make more pure. Could you soak in boiling hot ammonia to do the same thing?
Still trying to get the gold out of solution! I have dissolved urea till it won't dissolve anymore, added spoonfuls of SMB, still can't get the drop. Dumped it all into a bucket of copper. Will try again later. Coffee filters do not dissolve and really plug up the filters, working up to a vacuum filter set. Loving the stockpot series! keep up the good work!
If you were just interested in just getting the gold and silver out of the stock pot , could you process the solids the same way you’d process inquarted gold ? Regrettably , the PGM s seems too dangerous, and tedious, to recover with my limited knowledge and equipment . I really enjoy your videos . I have learned a lot . Thank you .
Wow, to think, that could have been disposed off, and all that lost!!!! Well done. How is the DVD sets coming along? Hint.... Hint.... Hint....

What do you do to clean your melt dishes? There's always a tiny bit of gold that bleeds off into the borax in my dishes and I've boiled them in water without much luck. Got a pile of them saved up in a bag in the corner of my shop. Was thinking a dilute sulfuric acid and water boil and then collecting the solids. Haven't tried soda ash yet either.
I've been able to get small amounts with my oxy/acetylene torch and borax. But the amount of gas it uses is high. I think I read somewhere that they must be crushed in a ball mill then the precious metals can be extracted chemically.
@@sreetips thanks for the replies, it's appreciated. With most things I do, I read about it first. I did find a thread on grf about using sulfuric acid to clean melt dishes. Apparently Harold wrote a "how to" on the subject, but I haven't had any luck finding that thread exactly, and considering the source it's most likely some handy info to know.
I'm curious why you chose zinc to cement your platinum this time. I've always watched you use copper in the past. Is there a specific reason why you need to use zinc in this case?
I use copper to cement silver, and copper in the stock pot because it's cheaper and it doesn't react as fast as zinc. Zinc is more reactive than copper. You seen how it bubbled when I added it to the PGM solution. Copper would not do that because it is further down the list and less reactive then zinc. Copper could be used but it reacts much slower than zinc. In this case I'm using zinc because it is more reactive than copper and it will cement the PGMs out of my solution much quicker. Hope this helps.
I would presume that the gray material is ash from the paper labels that where on the copper fittings you incinerator,, it looks like that with burnt filters too and a real pain to filter through
I can't remember ever seeing burnt paper looking like that. I have a sneaking suspicion that it may be some of the other PGMs that I'm not used to seeing. It's all very interesting none the less.
Starting with a dirty AR solution, being various metals. I only want to pull the gold out. Which is more selective to gold only? Copperas[ferrous sulfate] or SMB. I understand put the precipitate back in to clean more. I have been putting the filtered AR solutions[only liquid] in a stock pot with copper pipe, water and air bubbler.
I understand your left over solutions that go into your stock pot wouldn't have much nitric. Mine does, will this matter? Other then eat up some of the copper. I double the AR amount with water, but nitric will still be present. Should I add sulfamic to the stock pot AR to help kill the nitric? I was told as the copper is precipitating, the AR will redissolve, continuously. That I should have denoxed then double with water then into stock pot. Since my concentrates have a lot of sulfur. SMB wont work with my AR's. I have to get the metals away from the sulfur, then start again. I done the process with zinc, but was told to watch you. Your stock pot you use copper. Zinc will grab all metals that I dont want, copper only precipitates those below it.
@@sreetips Thanks for the answer to his question... uhmmmm... I googled eustabafelous and even GOOGLE had no clue what it was. I fully enjoy your videos and marvel at the font of knowledge you have on this subject. PS Your wife reminds me of my wife's mother. Many years ago she would go to garage sales and estate sales and buy up all the precious metals, she would really love what you are doing.
I filtered off the stock pot. I left it on for 4 days 1 day to settle, then filter. I could see black and brown specks, soaked it with HCl then rinsed with hot water 3 times, then put it in hot not boiling AR. 1 hour went by and there was still the brown specks in the bottom. Stannous test is real dark black, like blue/black color. There is about 200 ml HCl with about 20ml nitric. Color is yellow with green. All black specks are gone just fine brown specks? Dissolve long or what?
Would a stroke feel pretty good about now? then please allow me the honor sir. Ive been watching for a while and I really dig going back over the videos. Now I have since enough to know I would have a terrible accident if I tried my hand at this so all the experience I will ever have well probably be from a Sreetips video so I appreciate the way you show your successes as I appreciate the lessons which grow experience not sure I said that right but this is a genuine stroke sir.
So it seems like you're always gonna have some of that ultra-poisonous platinum solution as a waste product when you are done with this entire process -- what do you do with that? How do you get rid of it safely?
Ugh I was like man, what the heck happened to SREETIPS?!?! The quality wass 360P MAX RESOLUTION AND I HAVE A WONDERFUL COMPUTER/NETWORK connection so that's not it, other 4K streamed fine same PC different tab... THEN I REALIZED it had like 24 views or something and refreshed the stupid UA-cam window and got the 1080p 60Hz version continued from where I was at. I got on it quick! UA-cam hadn't even had a chance to process it through their codecs and other stuff they do so all i had was 360 which i kept watching until i realized I was being dumb! DOH! Keep doing what you're doing, be careful!
If you are already dealing with hot sulphuric acid, you might as well deal with your filter papers with hot piranha (add some peroxide to the sulphuric and you will turn any carbon containing molecules into CO2,) I'm not sure if it would leave metals alone, but since you are dissolving them anyways it shouldn't screw things up, be careful though, hot concentrated piranha reacts violently with organics, so be careful and don't go breaking out the rocket grade peroxide.
he's not really dealing with hot sulphuric though he's only adding a small amount near the end of refinings where most metals are in solution to remove any Lead that may have found its way through. I wouldn't be creating hot piranha solution unless I absolutely had to as that stuff can be really really nasty
@@CoinSilver800 fair point. It should still destroy organics at relatively low concentrations though right? If you just want to clean up some remaining carbon and potential ash I would expect a bit of peroxide to help. (Though switching to low ash filter paper would be my first fix)
Robert, there wasn't enough carbon left to be a problem. None of the refiners that I know have ever used peroxide in this manner. I believe you when you say it will work. Refiners use compounds that could produce violent reactions, right on the edge sometimes. But making piranha juice just to dissolve a few flakes of unburned paper it probably not a good idea.
Alconox then a quick rinse with distilled water. 80% of my distilled water usage comes from rinsing my glassware after cleaning it. You can buy alconox on eBay. Formulated for lab glassware.
1 gram stannous chloride. 1 gram pure tin shot. 25ml distilled water. 30 drops hydrochloric acid. Mix and use immediately. Lasts for up to three months.
Ok I AR my cons, filtered, then put urea in the AR to cut the nitric, then doubled with water, added copper pipe and some HCl and added fish tank air tube. The test that I done worked, but the copper that gets dissolved where does it go? Into the liquid in the solution and causes the precious metals to precipitate? I thought I removed all or most of the nitric, but the stock pot is eating up copper pipe.
@@sreetips Ok yesterday the solution was real green, today dark like black or brown with slight green tint. Day 1 gone, still bubbler mixing it. I dont see it eating any more copper.
The first time you disolved the incinerated materials it took 27 ml of nitric to dissolve all the material. After you dropped the gold and removed the sediment, it only took 5 ml of nitric to dissolve just the gold. So I'd say you had another 4 times the gold of other precious metals to start with. I would save that sediment!
I save all my filters. I've got a five gallon bucket full of them. If you're implying that I lost some gold you must first consider that the initial dissolution in hot aqua regia after incinerating will take much more nitric (27ml) to get the gold because of the recycling effect that happens when other metals are present with the gold. After the first precip and the gold has become concentrated and the other metals removed, it takes much less nitric (5ml) to get the gold to dissolve. This has been my experience.
@@sreetips I didn't mean to imply you lost gold. I was think you had other (precious?) metals in the sediment you filtered out. Could the grey stuff be lead? Or more likely rhodium?
Yes, there will be some other precious metals. I'm so deficient when it come to rhodium. I don't even know how to test the grey material to see if it is. But I've got the filter saved. They put you in the spam folder and I had to go in and get this comment posted for you.
Are u using concentrated hcl Because there is no fumes in your hcl When I use 32 % hcl fumes are outing and it making trouble when dropping SMB in AR solution I use ur method nitric dose adding I useing sulfamic acid for detoxing nitric acid
Excess HCl will make no trouble. Adding SMB to HCl makes big trouble in the form of sulfur dioxide gas. You don't see fumes because of the air flow from my fume hood, but they are there. If you dose the nitric properly then you won't need to denoxx at all.
46:07 el oro se forma un surco eso quiere decir que es oro puro? podrias hacer un video para saber como tu sreetips haces tus pruebas para ver si es oro puro 24k? porfavor estimado seria interesante , soy un alquimista
As someone that has never reclaimed or refined anything, I have to wonder why someone pours so much known gold solution into a stock pot when you are in the process of refining the stock pot. Why not pour the dissolved gold from the flask and beaker into the solution you were about to drop gold from?
@@sreetips I can understand that. I just finished the series. Very informative. I was anticipating the "disaster" because of the title but I never anticipated what happened. I look forward to your next video. Subscribing now.
Hi sir..I dissolve 95 gram gold in 500 ml hcl with 100ml nitric acid ..but at the end of gold dissolve it comes 300ml.. is there any mistake or it is possible acid will reduce
Re-purification. The stock pot contains a bunch of different metals. Junk tends to follow the gold. I dissolve and precipitate, using a different precipitate, to try and eliminate the contamination. But, as you can see, it was stubborn and I couldn’t get it out with five refining. In the end I think I inquarted with silver and started all over to get the hold cleaned up. Inquarting (alloying silver with the gold to make 25% gold alloy) then parting with hot dilute nitric does a fantastic job of cleaning the gold, removing those stubborn, hard to clean metals that follow the gold.
Neither, just a retired Naval Engineer with an FAA Commercial multi-engine instrument rated flight certificate - expired. But I do work at a jewelry repair shop.

And ends up in the Ag

Copperas solution would be CuSO4'H2O5 ?
Copperas is a ferrous sulfate
FeSO4 = ferrous sulfate
Have you tried sulfamic acid to denox? If I can find, or make some I want to give it a shot. How do you know when the nitric is done reacting to urea?
Iron supplement from Walmart is 325mg Ferrous Sulfate pills, a small percentage of titanium and magnesium. interesting
I'm pretty sure iridium doesn't dissolve in aqua regia either.

Alconox then a quick rinse with distilled water. 80% of my distilled water usage comes from rinsing my glassware after cleaning it. You can buy alconox on eBay. Formulated for lab glassware.
@@sreetips oh ok , thanks, ill have to get some. my glassware looks ferral
How do you make the stanis chemical to test the reaction liquid of gold , platinum
1 gram stannous chloride. 1 gram pure tin shot. 25ml distilled water. 30 drops hydrochloric acid. Mix and use immediately. Lasts for up to three months.
Ok I AR my cons, filtered, then put urea in the AR to cut the nitric, then doubled with water, added copper pipe and some HCl and added fish tank air tube. The test that I done worked, but the copper that gets dissolved where does it go? Into the liquid in the solution and causes the precious metals to precipitate? I thought I removed all or most of the nitric, but the stock pot is eating up copper pipe.
Yes.
@@sreetips ok thanks then its doing correct, its supposed to eat up the copper.
@@sreetips Ok yesterday the solution was real green, today dark like black or brown with slight green tint. Day 1 gone, still bubbler mixing it. I dont see it eating any more copper.
The first time you disolved the incinerated materials it took 27 ml of nitric to dissolve all the material. After you dropped the gold and removed the sediment, it only took 5 ml of nitric to dissolve just the gold. So I'd say you had another 4 times the gold of other precious metals to start with. I would save that sediment!
I save all my filters. I've got a five gallon bucket full of them. If you're implying that I lost some gold you must first consider that the initial dissolution in hot aqua regia after incinerating will take much more nitric (27ml) to get the gold because of the recycling effect that happens when other metals are present with the gold. After the first precip and the gold has become concentrated and the other metals removed, it takes much less nitric (5ml) to get the gold to dissolve. This has been my experience.
@@sreetips I didn't mean to imply you lost gold. I was think you had other (precious?) metals in the sediment you filtered out. Could the grey stuff be lead? Or more likely rhodium?
Yes, there will be some other precious metals. I'm so deficient when it come to rhodium. I don't even know how to test the grey material to see if it is. But I've got the filter saved. They put you in the spam folder and I had to go in and get this comment posted for you.
@@sreetips sorry for the multiple comments, not sure how that happened.
Haha, the lady wants her dollah, got to keep the wife happy lol
Also why use copperite the 2nd time as opposed to the SMB?
SMB will drop platinum group metals, copperas will drop the gold only.
Are u using concentrated hcl
Because there is no fumes in your hcl
When I use 32 % hcl fumes are outing and it making trouble when dropping SMB in AR solution
I use ur method nitric dose adding
I useing sulfamic acid for detoxing nitric acid
Excess HCl will make no trouble. Adding SMB to HCl makes big trouble in the form of sulfur dioxide gas. You don't see fumes because of the air flow from my fume hood, but they are there. If you dose the nitric properly then you won't need to denoxx at all.
very cool
Thank you
46:07 el oro se forma un surco eso quiere decir que es oro puro? podrias hacer un video para saber como tu sreetips haces tus pruebas para ver si es oro puro 24k? porfavor estimado seria interesante , soy un alquimista
En efecto, es oro puro.
45:05 to see the result
After 2 days of AR solution in stock pot with copper pipe, There is alot of white stuck to the copper pipe. Any idea what?
Not anything that I'm familiar with.
@@sreetips ok
As someone that has never reclaimed or refined anything, I have to wonder why someone pours so much known gold solution into a stock pot when you are in the process of refining the stock pot. Why not pour the dissolved gold from the flask and beaker into the solution you were about to drop gold from?
Good question. It was probably due to me being in a hurry to get a yield for the camera.
@@sreetips I can understand that. I just finished the series. Very informative. I was anticipating the "disaster" because of the title but I never anticipated what happened. I look forward to your next video. Subscribing now.
Sean, I've got all the paper from the spill. I'll make a recovery video from that paper. Thank you.
Sir Catholic converter dost 1 kg and Platinum Palladium and rhodium percentage sir please tell me sir
He's got several videos on catalitic converters already, check them out.
Hi sir..I dissolve 95 gram gold in 500 ml hcl with 100ml nitric acid ..but at the end of gold dissolve it comes 300ml.. is there any mistake or it is possible acid will reduce
If you heat it then it will evaporate.
If evaporate ...it is possible to evaporate more gold...
you'd be hoping it was rhodium mr Sreetips... @30k an oz (aud) you'd have the missus happy in no time.
Rhodium - to me it’s like the the four forces that hold everything together - an enigma.
You should try swapping to Quantitative / low Ash filter papers
I'm going to get a box and try them out. But those ashless filters are expensive.
Be carefull sreetips. I'd like to enjoy your video's longer.
And you know be carefull with what... How about other platinum group salts... uncharted territory?
I really think you should work with the longsleeve gloves to protect your arms to possible spatters of the solution.
I don't like working with platinum. No matter how careful, some will eventually end up on ya.
Man, I can't agree with just selling the gold outright. Also, why don't you want Ammonia in the stock pot? What will happen?
Clouds of ammonia in my shop
Why dissolve the gold 3 times?
Re-purification. The stock pot contains a bunch of different metals. Junk tends to follow the gold. I dissolve and precipitate, using a different precipitate, to try and eliminate the contamination. But, as you can see, it was stubborn and I couldn’t get it out with five refining. In the end I think I inquarted with silver and started all over to get the hold cleaned up. Inquarting (alloying silver with the gold to make 25% gold alloy) then parting with hot dilute nitric does a fantastic job of cleaning the gold, removing those stubborn, hard to clean metals that follow the gold.
MAN YOU HAVE BEEN BUSY!!
Yes, it's because I love doing this kind of work.
Why do you not want ammonia in the stock pot please?
Because it will produce a cloud of ammonia in my shop
@@sreetips thought so, just wasn't sure if there was any other reason. Thank you
You can have Rh in solution
You need to separate it
From Pt
Rhodium is completely out of my league. It will have to wait because I'll consider myself lucky just to get my platinum and my palladium.
👍
How do I find the items on eBay? Please help!!
Use the "search" block on eBay.
sreetips yes but what do I search to find your items?
My eBay user name is sreetips.
sreetips okay thank you so much!!!

One might wonder if you are a Chemist or a Jeweler.
Neither, just a retired Naval Engineer with an FAA Commercial multi-engine instrument rated flight certificate - expired. But I do work at a jewelry repair shop.
That is awesome, thank you very much for your service. I am a disabled Industrial and Commercial Electrician and kind of Jack-of-Many trades. I have also done some scrapping, dumpster diving.
