Another great video as usual, just finished the whole thing. I'm really curious about that black sludge that left over. might be interesting to take a gram of the black powders off that were collected, melt into a button and then zap it with an XRF just to get a real rough idea as to what you're dealing with percentage wise after running all the silver you have through all those silver cell runs. (this is more of a curiosity thing as the way you are doing it wet with stannous tests is working great so far)
Sreetips has always had some black stuff left over from his stock pot refinings and filters and stuff, and I've always wondered what is in there. As he seems to keep a rather clean operation it would be unlikely to be "dirt" or dust or foreign objects. so... what is it? xrf is the obvious way to go but even just see if it can be melted into a button would at least show if it's metallic at all.
Not sure why/how the algorithm directed me to you, but I absolutely love this content. I think you have taught me more about practical chemistry than my teacher in high school ever did. Thanks for sharing this all with us @Sreetips :)
Thanks for the video Sreetips, love watching your gold videos and the different variations/ experiments in refining them but must say the silver ones as of late are just as entertaining. Keep it up
Thank you for taking us on a journey to inorganic chemistry! It's very captivating to see how you solve problems and make use of everything, almost without any waste at the end.
As a person who works in STEM I have to say I thoroughly enjoy your videos. Often times working a new procedure I am confronted with unexpected results, coming up with a hypothesis and working towards solving an issue is a hallmark of good lab work. A possible reason for the initially low concentration of dissolved PGMs is the high excess of silver metal. According to the reactivity series of metals the silver will (in theory) be first to oxidize and go into solution, in practice a little bit of PGMs will go over as well. The best approach going forward is to continue the nitric acid boils until all silver is dissolved, the small amounts of PGM in solution can be plated out and recovered at a later date. For future electrolytic refinings I would suggest finding a way to mechanically separate the silver from the slimes, possibly by suspending the impure silver shot in a fine mesh nylon sieve above the filter basket. I hope this helps and continue the good work!
Of all the UA-cam rabbit holes I've fallen into, this is by far the most fascinating. I failed chemistry in college, so I am amazed that I'm just glued to these videos.
Can’t wait to see you do your paper filters, it’s all great and interesting stuff. Wish I paid more attention at school when doing chemistry and the like.
Enjoyed as usual. Doesn't look like it will be worth chasing the PGMs if stannous and DMG is showing that little. My thought is to filter solids out, add DMG to solution, then filter out precipitate and set aside, toss in copper and let the cycle continue. But I'm just being an armchair quarterback with that. I'm looking forward to see what you do with it.
Hello Mrs and Mr sreetips. I saw a person here on UA-cam who talks on silver prices. I agree whit him and you.... The silver prices most likley go up on day. Because there will be many who needs silver in the item they produces... I think you are spot on sir, when you talks abaut The silver... Period. The price as you say, can raise tomorow ore in 2 year. Have a nice christmas both of you, and rest of your famely. Thanks for all the work and clips in the year who soon is over. God stand by you, and give you visdom.. More passion.. More money.. More power. Thank you so muth🌹🌹 Arne
TBH I would totally keep a small jar of the crystals in the silver nitrate solution as a display piece. The silver crystal in that blue liquid looks beautiful.
Have you ever tried or thought about cleaning the original solids in the filter bags in your ultrasonic cleaner ? No idea if it is plausible But I’ve seen them clean things that were Absolutely mind-boggling . I know this is always a long process for and I am hoping to have enough amassed to try this endeavor myself sooner so I figured I would ask the master first. Thank you sir fantastic video as always !
Fascinating! The silver nitrate structures look like ice when it piles up in late winter as the lake expands. It's so different from the tree shapes that pure silver forms! Does this come down to how the molecules or atoms align in different states?
Some ideas: 1) Try to separate the mud from the remaining drops with a colander. 2) Extract the rare metals in solution with pieces of silver. 3) Your silver droplet have lots of copper, so try to mix the cemented silver with some silver salt (like chloride or nitrate) to oxidais the copper. (Sorry for my english)
You know, I’ve noticed you stannous chloride solution is always white cloudy color. For as long as I’ve ever had my solutions (years) mine always stay clear and still works just as good as the day I make it. I do put excess tin in my bottle so it can dissolve as needed and refresh the HCl acid when it gets low so maybe that’s why but I found that interesting. I think the stannous chloride crystals I have are non reagent grade but I do use the dihydrate version, not anhydrous. Still I don’t think that would be why. I’ve always wondered why mine never turned cloudy white color.
id love to see a video about machinery, glassware or environment that would help you do what you do if you were to do this for a living, comparing to what you use
Have you ever thought about selling the crystallized silver to crystal shops and collectors? . As a crystal collector myself I would love to get a specimen and I know that they would be very popular
Great video... and the moral of the story is, remove as much silver chunks as possible to save nitric and time and energy ane nerves... I think you do have ultrasound cleaner, isn't is possible to clean the filters with ultrasound just in water and screen out silver chunks with sieve? Just an idea...
My GUESS is that modern jewelery alloys are made by extracting all the PGMs first then rebuilding the name product with base metal. I'm NOT saying that there isn't gold in modern gold or silver in modern silver, simply the Platinum, Palladium, Iridium, Rhodium (and others) are removed for modern uses and sell for more than the silver or gold that hosts them. Gold can be whitened for white gold with nickel or Palladium. Any Pd found can be extracted and sold as Pd and replaced in white gold by nickel.
Mechanically separating solid silver shot from slimes - how about using a gemstone tumbler with water in it? And you could use the same tumbler with grit in it to strip off gold plating.
Rather than burning the filters, have you considered using piranha solution (concentrated sulfuric acid and ~35% hydrogen peroxide) to dissolve and oxidize them to nothing but CO2 and water? Given the volume of filter papers you have it might be less messy and time consuming than burning them and should leave you with a slurry-like mixture of finely divided material that would dissolve readily in nitric. Some precious metals (chiefly palladium to my knowledge) will also dissolve in the sulfuric acid but the resulting sulfate decomposes in hot water according to every source I can find. Just a thought on a way to at least reduce the volume and variety of solid waste you're dealing with. From my own experiences it's worked well on glass frit filters with gunky loads of tarry, horrible organic compounds so I can't help but imagine the opposite - decomposing a cellulose filter to liberate assorted inorganic particulates - would work just as well. Either way, cheers and happy refining. 😁
Also, added benefit of piranha solution is that it'll completely remove all the carbon, saving future filtration steps compared to dissolving precious metals out of ash.
I always love that slime!! Idea: have you ever though of putting one of those copper pipes into a solution like that, electrified? Maybe just as an experiment. I don't know yet how, but maybe the copper would catalyze a more quick electric cell crystallization or something.. copper might be in the way though. I wouldn't do it in your normal cell..
@@sreetips you have a system that definitely works.. I see you at it like a kid with a model train hobby. That is just so cool because you get paid to have fun. I guess if I ever get the chance to get into it I will do it, what I was suggesting as an idea ofncatalyzing an electric cell to be able to operate at high amperage and or voltage.
I reckon you've got way more palladium in there than you think, much more than that initial test with DMG, especially with the colour of the last filtrate being so green - combining the blue copper/silver nitrate with yellow aqueous palladium nitrate. I wonder how much rhodium might be in the black pgms. I guess it's mostly gold and platinum, but rhodium is now so ridiculously expensive, it is worth going after every milligram. Difficult to get out of there I know.
When you are testing your silver solution around 6:00 shouldn't you (also) be testing with some Schwerter's (dichromate) to see if you've precipitated all your silver into chloride? Or will Schwerter's test positive for silver even if you have converted all the silver into chloride? That seems like it would be good to know, even if not useful for a test.
SRTPS.....As I said before, spent years in Metallurgy labs for Atomic Energy doing R&D on metals and coatings, and as you said, making this up as I go along, you end up like Columbo as a detective, try one thing, keep trying......Even with the same solutions, metals, reagents no two jobs are ever exactly the same.......your doing fine bud, absolutely fine, a great chemist and metallurgist.
You know… if the concentration is so highly saturated with silver, it actually makes sense that it’s the only one in solution, as the PGMs would preferentially separate out before the silver nitrate started crystalizing, right?
Always a awesome time! Great knowledge for sure! I have some of that stannous chloride crystals. The instructions say just mix with water. Do you think it's a different product than yours? Or is it just a better solution using your method?
I use a gram of stannous crystals, a gram of pure tin shot, 25ml distilled water, 30 drops hydrochloric acid. Shake, use immediately. Lasts up to three months.
@@sreetips Thank you Thank you Thank you! The way I make it. Just mixing with distilled water, it seems to last maybe a month. Plus I'm sure the 110 degree weather here in the desert probably doesn't help any. And you are getting way more fluid than what I get. I get a whopping 4ml per 3 grams of crystals. I just need to get some pure tin shot.
At least now ya got quite a bit of silver nitrate solution to add to the cell later on that should last ya some time I'm definitely gonna try this if I ever get a power cell
@@sreetips it doesn't look to be much fun thats for sure wasn't expecting a few day series on this haha figured a good hour video but hey getting to learn a lil here some stuff I never knew about which is very fascinating and if I can ever get a power cell the lil flea market across the street from me the guy has junk silver jewelery and get old sterling silver wear to so that will make it easy to get stuff just have to figure out where to get the nitric acid that ya use inthis process to make it all happen
I’ve been watching for years, it’s looking to me that the solutions are dehydrated, adding distilled water causes problems… that leads me to believe that you should use more hydrochloric acid.
What is the conversion ratio of impure shot to pure crystal? Im sure the purity of the shot plays into the equation. A simple to understand guesstimate would be great. For instance, on average, how much pure silver crystal would you typically recover after feeding the cell 1,000 grams of impure shot that has a purity of .900fs?
Put 1000g of 99% impure silver in, get 990g of pure silver crystal out. Pretty much near perfect return. Some of the silver from the electrolyte plates out as the cell operates.
@@sreetips I assumed that was the case. I still like to imagine the idea that you’re growing more pure silver than you’re feeding it 😅 I understand the cell’s purpose is to allow you to create a .999+ pure product. Thank you for the exceptional content you continue to provide 👍
It’s hard enough because I’ve only done this a couple times. Throwing the camera in the middle makes it that much more difficult. The next time I do these filters will probably be without the camera rolling.
Hey sreetips love your vids. I was thinking, if you had put pgms into solution in part 1, wouldn't they cement out on the leftover silver pieces overnight? It would explain why you had the negative stannous test, and if that's what happened, could you use sterling silver to cement the pgms out of solution instead of using dmg to seperate?
No, I’m a retired Naval Engineer with a degree in aviation. I took one chemistry class n high school 50 years ago and got a “D” and never took another.
@@sreetips Ahhh well that answers my question too, you said in the video that thankfully you didn't have to do this for a living, I was going to ask if you knocked over pwn shops instead...Mrs. Sreetips being code name for your sawed off... :-)
Hey Sreetips, what kind of ounce yield do you get out of the silver anode? I have to think you'd need to process a lot of silver at once to make it worth your time.
I get about 1.5 kilos of pure silver crystal from the silver cell about every ten days. I pretty much get out exactly what goes into the cell in terms of the amount of silver. But some silver plates out of the electrolyte as the cell operates.
I'm not an expert like yourself here, i wounder why you don't melt the undesolved metal and send it to analysis. So you'll know what you're dealing with
Perfect timing. Bored at work. Not bored anymore lol
That Stannous Chloride Testing Solution is so neat. I never knew you made it yourself. Thank you for sharing your hobby with all of us.
3 liters of beer in and this is the most entertaining thing I've ever found on UA-cam. Wisconsin boys represent!
I'm excited to see when you finally make a refining video where you're recovering the precious metals from that shirt!
Class is in session. Nice work, even if you are making it up as you go along.
A joy to see. Best of luck!

@@bloodyricho1 where would that come from, you think?
It is more likely a tin and or lead oxide from the ore solder etc

And where would it come from? (To be cemented out on copper?)

The black, nitric insoluble, material should be precious metals. How much of what kind is a complete mystery until we finish the series.
@@sreetips you seem to be hunting for PGM's, hopefully you find some.
Do you ever reuse those anode filters after cleaning them with nitric boils?
No, they are custom fit for each use and it would be nearly impossible to get them back into the anode basket properly.
What is in the slimes. This time that is so black? I'm going to quess. Oxided silver.
I don’t know
Hey Sreetips, what kind of ounce yield do you get out of the silver anode? I have to think you'd need to process a lot of silver at once to make it worth your time.
I get about 1.5 kilos of pure silver crystal from the silver cell about every ten days. I pretty much get out exactly what goes into the cell in terms of the amount of silver. But some silver plates out of the electrolyte as the cell operates.
@@sreetips So you just run the thing constantly?
Yes
Is this palladium radioactive?
No
HAPPY FATHER'S DAY DUDE
Thank you!

Salt is cheaper here but kudos
You need a bigger fume hood ;)
Agree
I'm not an expert like yourself here, i wounder why you don't melt the undesolved metal and send it to analysis.
So you'll know what you're dealing with
Didn’t think of it
I want to drink it
Are you normally able to use SnCl₂ directly after making a fresh test solution? I always have to wait a few hours for it to start working.
Make it, shake, use immediately
