love the experimentation, it's like an adventure with all the perils, pitfalls, and casualties (RIP melt dish) so much drama and suspense, even setting changes (going outside to the furnace), and a brutal antagonist (PGMs) holding your beloved beakers hostage
My thought process is to cornflake (melt and pour in water like you do inquarted gold) then dissolve in nitric. Filter, then convert to silver cloride and convert to pure silver via the sugar and lye method. The waste fluid then should contain the PGMs that you cement out on its own with the silver removed. To reduce the amount of liquid waste you would have to treat could put it in a large heatable container, and boil it down to remove the water. But thats just my thought process. You usually come up with a more efficient process.
Interesting brother. Silvers ruined my week too . I have 4 kilo of 24k gold plated pins trouble is the pins are silver. So I have beakers with different methods in each. I think my problem is I should be trying to recover silver first. Who knows anyways brother thanks for another awesome episode.
Binged all six episodes over the last 24 hours. I see good advice in the comments but good luck with the path! This is better than anything out of the MCU!
This is great. I love the experimentation along with the wins and losses. All part of the fun. The best part is most of your hobby is actually still there when you mess up a little and you can recover. Stamp collectors, for one, can't say that. I still say if I am ever down your way I am going to bring you a 55-gallon drum of your favorite nitrogen oxoacid. 😉 I've been riding with you a long time, Sr. I'm pretty comfortable in this seat, you know. 👍🖖
My dad tosses his stamps collection, I got a bunch of comics that I’m resisting reading for whatever reason the whole bit is only $30 for now. There’s various reasons why some things are valuable. Metals have many more utility uses and demands for them. Each individual metal in a pure form. Is a better end product than a mix that may give undesirable results in alloys or electrical components. Heatsinks for example would be best made of a silver alloy yet consumers still get aluminum (heat capacitor) and copper which is the third best. Steel had the best transfer speed but resists absorption of the heat… just reflecting it back at the source more than taking it away.
I know you are in a bad place, but this has all been a learning experience. Here is what you do now. 1. Dissolve all your Ag and Pd in nitric. Then add potassium hydroxide to the solution until you reach a pH of 6. You should see a dark precipitate form, this is Ag2O and PdO. There will still be silver in the solution. 2. Filter the precipitate removing all nitric. Then in the filter, pour HCl through the precipitate. This will form insoluble AgCl and soluble PdCl2. You will see a yellow-orange solution in the flask. Continue adding HCl until the filtered solution runs clear. Filter the captured solution until clear. You can convert the AgCl to metallic Ag using the sugar and lye method. 3. Decant the PdCl2 to a beaker and raise the pH by adding sodium carbonate. You can now precipitate the Pd by adding ascorbic acid. Continue adding until you see no more precipitate forming, then filter. 4. Wash the Pd with HCl and then distilled water. You now have clean metallic Pd.
I think you might possibly be dealing with rhodium and palladium and platinum, these are like Hearding cats, some can go nitrates some oxides some in 2+ 3+ aquas states etc, that yellow line on your experiment over copper could be rhodium nitrate. The pgms can also Adsorb chlorides and change states when aquas through lots of colours. For instance with Rhodium Chloride hydrate states, you can go green yellow reds brown blue at different ph. ranges. you may not be seeing it on the stannous chloride test as can be in a range of states, If rhodium going to be tricky but I have seen it like this before, as in solution with nitric may be present as 3+ Aqua complex etc with Associations with nitrates and in a mixed matrix, Maybe get it back down to remove silver nitrate crystals and the rest of the green liquid filter from the crystals, boil down and denox with hck as usual add ammonia chloride and PH balance with some sodium hydroxide to about PH3 and see what precipitation you get will probably look like a mess when you do it but stir up and let settle and see if it's a reddish colour or orange or yellow. If dealing with 3+ Aqua complexes I have had success with that method for Cation and Ligand Exhange, the liquid should stay green up to about ph 5-6 and keep dropping the rhodium and palladium out. at about ph 7 and above will turn blue if doing it in stages this will be RH4 (Blue Rhodium). at different PH ranges the precipitate will be different colours at ph 3 should see your reddish colour, and will be an Ammonia Hexochloro Rhodiate /Platinate / Pallidate.
Also id dealing with rhodium, and you still have black/ grey material that is not digesting due to passivity nitric won't touch it, best in AR with only low amount of nitric
actually, looking back over your video, rhodium doesn't alloy with silver well so your furnace is probably an easier separation as the palladium will drag down with the melted silver and the rhodium oxide will float ontop as could be observed, then tip the silver out of the crusted rhodium oxide shell @@sreetips
From my understanding a lot of silver plated utensils as well as jewelry had a thin layer of rhodium so that it wouldn't lose its Shane over time we all know that silver turns black when it oxidizes this would prevent that from happening so I'm pretty sure a lot of that black powder that does not dissolve into Nitric is rhodium looks like you have a nice little chunk of change there Mr Streetips
If you take your silver PGM in nitric solution then add some of your pure silver crystals, that should saturate the solution with silver and force and the PMGs out of solution which could then be filtered out. It may not work for reasons I am unaware of but in theory it should
@@sreetips Sometimes I use the 48 hour rule. If I don't like how it's going. I walk away and clear my head and comeback in 48 hours. If that doesn't work I move on and count my loses as wins. Because in the end I still have my family and that all I need
Me too. I’ll get this complete in some form or fashion. It’s been sitting there taking up room long enough. I get a knot in my gut every time I walk past it. Time to move!
Well, I think, that you have too little PGM material in your case. I would suggest dissolving all of the PGM containing material (except the silver flakes in last beaker shown in the video) in nitric acid. Precipitate silver as silver chloride (maybe, using simple table salt, just making the process cheaper and less acidic). Cement out all the PGMs using copper or zinc. Restore the silver from silver chloride and use it (alongside with undissolved metal silver flakes, that I mentioned before) in the silver cell as usual. Concerning the cemented PMGs, I would suggest either: melting them in a button and just selling them as is or gathering several batches and only then trying to purify to separate PGM metals.
"Concerning the cemented PMGs, I would suggest either: melting them in a button" Last time he sold a mixed PGM button he only seems to have been paid for the most valuable part of the mix, not for the total value.
@@NorthDownReader I understand that. While selling something, you should always think, if it is worth purifying less valuable part from the mix (it might be not worth putting all of the reagents, your time and effort in to it). I think, that, it might be worth it, if it "becomes" the content for the future videos.
I have some mystery jewelry that behaves like this. A chain and a couple old 'silver' earings. Even AR barely touched it, and the metal seemed to drop right back out as a gray-black powder as soon as the solution cooled. The only metals I've heard that can do that are the ultra-unreactive Pt-group metals like iridium and rhodium. But I can't imagine them being made into jewelry. I still have the powder and the parts of the jewelry that refused to dissolve in anything.
Very likely it's sterling silver plated with rhodium to prevent tarnishing. Rh is tougher and used to be a lot cheaper than it is these days, so some silver from the late 1930s through the 1960s did get various amounts of rhodium plating. Marcasite earrings for example. Usually it was pretty thin but it could well be a thicker layer depending on the quality.
@@AndyGraceMedia Hmm, that might be it. The jewelry does look like it came from that era, definitely old styles and crafting. Still, I didn't see any silver chloride. It was all grey-black. The chain is the most mysterious, intensely unreactive, even gently boiling in AR for several hours only dissolved a small portion of its mass. Maybe it's MAAAAAAGIC! It could be... MITHRIL!! :O (lol)
Dude, are you ok? Never in all the years I've watched your channel have you had sooo many things go wrong in such a small space of time and so close together, yeh mistakes have happened in the past, most memorable was the spill on the floor years ago, but things have been mostly recovered without too much trouble, but lately things have not gone so well, like you're distracted and your mind is elsewhere, so i had to ask, are you ok, are things ok in your life right now? This kind of work takes a lot of focus, i don't think i could do it, my hand eye coordination is terrible. I'd be so clumsy and knocking things over! I hope you're ok?
I’m losing metal capacity. Sight, hearing, coordination, things that used to be intuitive have to be thought out. In short, I’m getting old! But this comes with the territory. It’s not a bad thing. It just means I’m a little closer to going home.
Well that looks like a whole lot of work but where to start can't wait to what's recovered what losses are acceptable but mainly the process you choose to use for maximum return on the silver
What do you think about just doing a smelt on the anode slimes with cement silver as a collector metal and pouring shot frok that charge and running a special batch on your silver cell so you have that much less material to work through, since the slimes woud contain less nitrates and colloids and a concentration of PMs?
"doing a smelt on the anode slimes with cement silver as a collector metal and pouring shot frok that charge and running a special batch on your silver cell" Dirty silver seems to not go through - the lumps get coated with slimes and dirt, and don't process. There are some rectangular chunks that I am sure I have seen at least twice in the slimes videos.
when you had your crystals of silver nitrate I would have tried pouring off the liquid and washing the crystals in a solvent that wont dissolve the crystals. According to wikipedia the solubility of silver nitrate in acetic acid is very low also Acetone is low but not as low as acetic acid. I assume the figures are for glacial acetic acid (concentrated). you would need the fume cupboard though.

I had Mrs sreetips read this and she was very impressed. She said tell you thanks, and that it made her very happy! She said you need to write more poetry.
i wonder about doing a cupel of what you have, to pull out atleast the copper. anything else that oxidizes away, just makes the silver easier to deal with. :P
@@sreetips oh look, something new to learn :P but, it is used to help refine raw gold from ores, to help remove collector metals and the like. but, the same thing would remove the copper and the like, in your system.
It's been a while since your last video in this series but if I remember right there were PGM's as well as gold and silver in solution. Are there no previously established refining processes to follow for such a situation? Refining one by one...by process of elimination which is what I know you are struggling to do. Seems like someone would have mapped out a game plan by now on how to tackle this in order of ease or necessity.
I bet that Sreetips is even more eager than you are to have these messy potions sorted out and to have his lab glassware clean, dry and back on his shelves! ;)
@@youssefzouine8191 It was a lighthearted comment about the mess Sreetips has on his hands. No need to blow a fuse and show the world that you're an ill-tempered and disagreeable person.
@youssefzouine8191 There is a clear translation failure here. 😂 No one but sreetips was mentioned in the comment. It was agreeing with you that we all are eagerly awaiting his video. Even sreetips.
Why not cement out with copper, filter and rinse off solution, then put the silver metal into AR to remove any pgms and leave the silver metal behind? I wouldn’t imagine as long as the silver is in metal form, it wouldn’t go into solution with AR. Then you’d have relatively clean cement silver along with any potential pgms removed leaving the silver cell to do minimal work.
Question. If you melt the cement silver into bars will you get the same price per OZ as with the run thru the silver cell? ( if you ever sold the silver)
The cement silver is questionable purity. The pure silver crystal is three nine plus. Industry standard for pure silver is three nines or 999 parts per thousand.
@@TroubledOnePaydirt the water/sulfuric reaction produces much heat. That’s why there’s a rule of thumb: always add acid to water, not the other way around. Adding a single drop of water to a beaker full of sulfuric acid produces so much heat so rapidly that the steam “explosion” causes hot acid to spatter everywhere. I’ve seen this happen. However, if I add a drop of sulfuric acid to a beaker full of water, nothing happens. The acid gets diluted fast and dissipates any heat from the reaction very rapidly.
I think he meant distilling water to use for your rinse water, I doubt you could do it for less than you are already paying already for your distilled water@@sreetips
Sr. Chief, I need your expertise. I have 650 grams of GF material. Should I do them in small batches, 100-200 grams at a time or just go ahead and do all 650 grams in one shot?
What about trying to cement out PGMs out of silver solution on pure silver? Maybe this way you will remove PGM without adding anything new to solutions.
That was my thinking but, a nagging doubt tells me the PGMs may precipitate out as a slime rather than a true solid potentially creating an even bigger mess
@@sreetips And incidentally your plates seem like a better choice than actual beaker caps which are often unnecessarily expensive and more difficult to handle than those simple plates of yours because the diameters of beaker caps tend to be too close to the diameters of the beakers. It's obvious that your plates do the job perfectly well, assuming that they never shatter off camera because of temperature variations.
@@sreetips Ah ok, yeah, I didn't really doubt you were using suitable filter papers. Your silver buttons look just like one I made, however my mate at work put in a GFC filter paper, not knowing they were actually made of glass. Caused the button to have a black rough looking underside.
@@sreetips fair enough sir … I spent a few years as a knife maker I 100% get it… there are probably thousands of dollars worth of knives I chucked up on the roof of my old shop
Ohh man tell me about the cottage cheeze man dont ever put ammonia to turn it back to liquid and try to wash it out with hot water man that cottage cheeze you cannot get it out of the beeker it coats it man you have to put it in water with hot water and dish soap if not you wont get it out you can even pour hydrocloric in the beeker it wont get that cottage cheeze out plus ammonia and hydrocloric together turns almost yo dry ice it get freezing cold lol hahaha

I wouldn’t imagine as long as the silver is in metal form, it wouldn’t go into solution with AR. Then you’d have relatively clean cement silver along with any potential pgms removed leaving the silver cell to do minimal work.
That’s not it would go
Question. If you melt the cement silver into bars will you get the same price per OZ as with the run thru the silver cell? ( if you ever sold the silver)
The cement silver is questionable purity. The pure silver crystal is three nine plus. Industry standard for pure silver is three nines or 999 parts per thousand.
What size are your crucibles?
I don’t know the size
🎉
can you cupel sterling with copper and if so what volume per oz of silver
I don’t know anything about cupel.
When other refiners put sulfuric acid in water, it foams and sizzles real bad. Why doesn’t yours? Different strength acid?
I don’t know. But if I put a drop of water into a beaker of sulfuric, it boils and bubbles and spatters pretty good.
@@sreetips well now I’m really confused. 😂😂
@@TroubledOnePaydirt the water/sulfuric reaction produces much heat. That’s why there’s a rule of thumb: always add acid to water, not the other way around. Adding a single drop of water to a beaker full of sulfuric acid produces so much heat so rapidly that the steam “explosion” causes hot acid to spatter everywhere. I’ve seen this happen. However, if I add a drop of sulfuric acid to a beaker full of water, nothing happens. The acid gets diluted fast and dissipates any heat from the reaction very rapidly.
Instead of breaking the crucible, could you remelt it and pour it into a mold or something?
Possibly
I was wondering what happened to this series… lol I thought I just missed the notifications. I guess not.
I put it on hold. It sat long enough. Now it’s time to get it done.
Buy some cupels…. Does wonders. My oh my what a little lead and a cupel process can do… cheaper too
Is there a way to distill your rinse water? Maybe buy less water and have less liquid waste?
The rinse water is distilled water.
I think he meant distilling water to use for your rinse water, I doubt you could do it for less than you are already paying already for your distilled water@@sreetips
Right. Recover the used water with a countertop distillery. Less waste to process
I just don't know what the individual acids you're washing off will do to the distillation process

Sr. Chief, I need your expertise. I have 650 grams of GF material. Should I do them in small batches, 100-200 grams at a time or just go ahead and do all 650 grams in one shot?
Do it in a fume hood. No way to safely do it otherwise.
@@sreetips Yes sir! I will be doing that. Is one way better than the other or really doesn’t matter how I do it?
I’d do a small hundred gram batch to start. Get a feel for it. Don’t skip the incineration BEFORE putting the gold foils in aqua regia.
@@sreetips Your talking about after I filter the gold foils once the dilute nitric acid boils are complete?
Yes
What is DMG again? I’m drawing a blank here.
It's dimethylglyoxime (C4H8N2O2).
Can you help me? What rhodium chemical precipitates pure rhodium?
I think pure grain alcohol, but ive never tried it.
Thank you you are a kind person
I am Vietnamese
@@kimhoanh5118 I don’t have any experience with rhodium.
Can't believe your bowl didn't break
Before you hit it with the hammer lol
What about trying to cement out PGMs out of silver solution on pure silver? Maybe this way you will remove PGM without adding anything new to solutions.
I don’t think that would work too well
That was my thinking but, a nagging doubt tells me the PGMs may precipitate out as a slime rather than a true solid potentially creating an even bigger mess
We're did you get your beaker covers from
The thrift store. Glass plates and saucers.
@@sreetips And incidentally your plates seem like a better choice than actual beaker caps which are often unnecessarily expensive and more difficult to handle than those simple plates of yours because the diameters of beaker caps tend to be too close to the diameters of the beakers. It's obvious that your plates do the job perfectly well, assuming that they never shatter off camera because of temperature variations.
I did have one break once when I sprayed it off with cold water.
What grade were them filter papers?
Whatman number 2 medium flow, lab grade.
@@sreetips Ah ok, yeah, I didn't really doubt you were using suitable filter papers. Your silver buttons look just like one I made, however my mate at work put in a GFC filter paper, not knowing they were actually made of glass. Caused the button to have a black rough looking underside.
I have glass fiber filters for use when filtering sulfuric acid.
Did you try cuppeling any of it? Sorry bout that spelling. lol
No
Why break the melt dish … just re melt it and then pop it before it cools as much
I wanted to take out my aggression on it because it took too long!
@@sreetips fair enough sir … I spent a few years as a knife maker I 100% get it… there are probably thousands of dollars worth of knives I chucked up on the roof of my old shop
Re-upload?
No, this is new content.
@@sreetips I had completely forgot about this series!
I added links in the description.

Ohh man tell me about the cottage cheeze man dont ever put ammonia to turn it back to liquid and try to wash it out with hot water man that cottage cheeze you cannot get it out of the beeker it coats it man you have to put it in water with hot water and dish soap if not you wont get it out you can even pour hydrocloric in the beeker it wont get that cottage cheeze out plus ammonia and hydrocloric together turns almost yo dry ice it get freezing cold lol hahaha
zero checklists ..
Each refining is different.
