Good evening Sreetips, Oh the calamity in refining precious metals. That's what makes this hobby fun and challenging at times. Great content. Fun to follow along. Stay safe bud.
Man.. that Palladium/Silver solution gave me second hand anxiety.. but now I'm excited more than ever for the next episode. Seeing you problem solve on the fly is great content. The "main prize" is probably going to take a week to filter.. 10 hours in and you're not even at the bottom where all the material has settled. See you next week I guess haha...
Great video, but I had a few questions. 1. Does water dissolve the yellow precipitate? I know you use hydrochloric acid to rinse when you work with PGMs salts. 2. Would converting the silver nitrate to silver chloride been a bit easier to separate from the PGMs? I do get that the method makes a lot more waste, but could allow you to isolate the other metals more efficiently.
As it takes AR to dissolve PGMs, I suspect (but don't know for sure anymore) that PdCl is soluble. If so, I would precipitate the Ag with HCl, which is already one of the standard steps in refining it, leaving the Pd in solution
Long time big fan sir..... Always love ur these series of stockpot refining, silver cell slime refining n filter paper stock refining..... Although missing longer videos..... Keep up ur great work sir
Mr. Sreetips, i have what might seem to be an odd request for you. Is there anyway you could make a 20-30min video thats just the sound of your fume hood along with the vacuum pump cycling maybe? That sound knocks me right out to sleep, i'd love to loop that noise all night, i'd sleep like a baby. No worries if not, i'm not so entitled that i expect you to actually do it, but it would be really nice 😁
Looks like it’s time to invest in a centrifuge! Spin down those hard to filter solutions before you filter them and you’ll save so much painful waiting
I've been wanting to see this phase of the process for some time---recovering the ugly silver from the anode baskets. It's clearly not easy. I don't recall your having covered this phase before. And it also should be said that it reduces your silver yield, or said differently, ties up silver from your gross yield. I wonder if there is a melting solution to this issue. I have not checked the melting point of Pd or Pt nitrates, but Pd and Pt metals melt much, much higher than silver. In my estimation, unless you see some big problem with it, it would be worth it to take two anode baskets full of that ugly stuff and cornflake it.
I’ll say it again, I am always so grateful to see when things don’t go as planned and the methods you use to get back on track. That’s where real learning happens.
@@MrTk6969 Well, Mr. S has a YT channel where he gets paid by us folks who enjoy the entertainment and knowledge, so the best thing that can happen is to have a problem worth solving that takes a few episodes to resolve. -- Dave
Sreetips I don't want to ask but I'm going to. I want a quick list of the items list for the gold refining. I'm setting up expense forecast and don't know the name of these beakers. But I want your setup. I have the silver cell list already help me out if you could. I'm your biggest fan. Your my favorite TH-cam dude! You are so well spoken, and can tell your a good old boy. God bless. I'd literally do anything for you! Thank you for teaching me value. God Bless! If you don't you don't worry about it! I'll be 👍
Hey sreetips I left a comment on your previous video that I think you will find helpful and with this vid I think you should dissolve the DMG PD salt in nitric acid then filter and add HCL to precipitate the silver out as silver chloride which would be easier then bubble chlorine through the PD solution or add sodium formate and boil the solution and lower the PH
Cool Chemistry!! Your best bet to separate the elemental silver from Pd(DMG)2 is to dissolve the Pd complex in hot ethanol or acetone -- the Ag should stay behind and be filtered off, and the Pd complex will recrystallize from the ethanol or acetone when you add some water Good Luck!!
Have you ever tried your ultrasonic to settle things? Not in it, but run it with your beaker sitting on top of it? Micro vibrations. Just throwing ideas out.
I was also surprised you didn’t do a stannous test on the filtrate prior to throwing in the copper to cement? Obviously you’re going to be running the silver through the cell again, but would have been nice to check for other pms before the cementation :)
⭐️⭐️⭐️⭐️⭐️! Nice pivot and progress capture. But please please please consider making a temp backsplash for your filter station area for the DMG precipitates 🙏🏼🙏🏼🙏🏼 that was the only anxiety inducing part of the video for me. Tutorials on how to clean up walls and windows from chemical splash damage are not fun to watch nor the type of content you probably want to have to make 😅😉
It looks like the majority of your anode slimes (the gray power after removing the silver shot) was cement silver. So I'm wondering where it all came from. Your silver starts as shot with no power. It dissolves in the electrolyte when oxidized by the current. Most of it travels to the cathode bowl, but why is so much precipitating out in the anode basket? What could be reducing it there at the same electrode where it oxidized? My guess is that it's the copper impurity in your silver shot. We might expect all the copper to be oxidized by the electric current along with the silver. but as each copper atom is exposed (as the around it dissolves) there is a chance it will be oxidized by Ag+ ions, creating cement silver. So it would be worthwhile to reduce the copper content of your silver shot. Obviously, the Cu comes from the CuNO3 solution that the silver cements out of. Now CuNO3 is super soluble in water, and you wash the cement silver with boiling water. But it still contains some copper because we see the electrolyte turn blue. The human eye is not very sensitive to blue. Maybe rinsing until you can't see the blue tint isn't good enough. In a research lab you would use optical spectroscopy to verify the last rinse is clear. You could do something like that in your home lab, with just a white light, a photocell, and a volt meter. By comparing clean water to your rinse water you should measure less voltage from the photocell when there's copper in solution. It might be even easier to detect the copper ions fro the conductivity of the water. Pure distilled water doesn't conduct at all well, and any ions in solution will increase the conductivity immensely. Second, I would suggest boiling your cement silver in distilled water after rinsing (just like you do with your gold precipitate). And third, I suggest your rinse the silver with ammonia. If some of the CuNO3 is stuck to the silver surface the ammonia should release it.
@@sreetips Smelting in a crucible, melting in an oven...my question basically is as a first step consolidating everything down into a single alloy of metal - (High silver content), then cornflake, then nitric boils, and so on. Just my engineering brain thinking of ways to reduce all the liquid being used. I was just curious....I've been watching Jason at MBMMLLC too much! ;) Thanks for the great content!
You should be able to end up with a clean 99+% palladium salt cake with almost no silver. It's a fascinating problem. I can only say that the possibility of encapsulation of silver chloride is possible and there are many other optional possibilities. It is important to add the DMG slowly with plenty of sheer mixing but I'd not expect significant silver in the salt cake.
I’ve been wondering if you could store the gold sponge material instead of melting it and pouring it into gold shot, buttons or bars? I was just thinking if your house was broken into most people wouldn’t even know what it is. I watch your videos way too much, by the way. It’s so interesting especially when you are figuring out new issues.
I forgot to mention the other day there is a healthy collectors market for Electrum. You will have no problem selling small Electrum buttons for the same price as 9999 gold plus a premium. People like it because of its history in ancient coinage and jewelers love it as do mineral collectors. Its hard to find someone to make it from pure gold and pure silver. Being man made is no problem to collectors. Might be a market for you.
As always, thanks for the great videos, however I’m really curious why you decided to use DMG prior to an hcl precipitation of the silver? You KNOW how sensitive the silver in solution is, and performing an hcl drop of the silver, rinse and filtering, and then a DMG drop would have been my personal recommended method due to the obvious potential issues of having silver drop out with the slightest contamination of solution. I would have sworn you’d know better, but maybe you were simply experimenting or being curious with the DMG prior to au drop?
Hi Sreetips... Have you got a video on how you ditill water? .... I see you use a lot.... Love the videos. Keep up the good work... Hello to Mrs Sreetips.... Sydney Australia.
I would love to see you do something with Titanium. I know it's not you're thing, I love your content regardless. But it is possible to get titanium jewellery these days and I just think with your skill, it would be interesting content from a knowledge and understanding point of view even if it's not necessarily profitable for you. Thumbs up for this video though, I'm mesmerized when I watch you're stuff, maybe it's just me but I still struggle with the idea of 'metals as a liquid' and I find it fascinating that you could have pot of fluid and basically decide which metal you would like to produce today, select your chosen acid/chemical and just watch the gold, silver or whatever literally fall out of the liquid. I'm blown away! and I've been watching you for years! 🙂
Question: I've seen you use lots of copper over the years, usually copper pipe, but have you ever fully recovered the copper and smelted it down to used to cement out silver? or is it too expensive and time consuming?
I can hardly see that being worth it. Copper in the form of wire or pipe is remarkably chemically pure, usually well over 99%, and certainly very cheap compared to silver, much less gold. And melting copper (in air) results in this scabby, oxidized surface. Whatever would be required to obtain clean bright copper from either the stockpot or the cementing, whether fuel to melt or nitric, I can't see the effort being worth it. I don't know whether the scabby copper from melting in air would be suitable for Sreetips use. I could definitely be wrong, but he's got enough farting around with chemicals as it is.
😂😂 it's all here in the channel... even the literature books of streetips fundamentals. It has been awesome to watch streetips move into HUGE production levels only dealing with mostly scrap jewelry/silver and it's collectively (this awesome Palladium/ Platinum drop wouldn't happen without the years of collection/refining.)
@@taxesdeathandtrouble.1886I'm sure you remember the early days where streetips was very open 2A (it was on the bench and certainly looked like a paper weight to me but YT don't like that, just like talking real about governments/money, pretty quick gets you blacklisted
Palladuim black is what is in the beaker you can precept with vitamin c and soduim bicarbonate and a lil heat it flake the palladuim black out the way you can tell by the ink black mirror look on the beaker buddy lol great video
Why don't you first precipitate silver from precious metal solutions in the form of AgCl? AgCl can then be reduced with aluminium/zink in acid, or by cathodic reduction
@@mattgraham1983 who cares how much I live watching and learning how to do this sreetips knocks them out of the park each time great education video's real to much fake crap out there and I'm tired of lies and false hoods
@@PaulBrown-uj5le there foreign and a few that are American when I first started watching these 4 or so years ago the first time I watched they made the claim about how much gold they refined from scrap computers and gold plated jewelry it showed some of the process but not all and at the end they claimed they got 12 gram or a 5 gram button from only one bag of plated material back then I thought it was honest so I started saving and buying boy did they fool me
@@PaulBrown-uj5le I enjoy this I had gold that my grandpa gave me for years from his claim in Arizona every place I took it tried giving me far less than what gold spot was so I started trying to learn how to refine it I had lots of nuggets and flakes but they all said it was not pure gold so I held onto it and tried many times to refine I was about to give up when I saw a sreetips video that's when I knew I was hoaxed about gold plated then I seen the one he did of nuggets of gold and the fact it's better to incorporate silver in the process I've been watching sreetips ever since it worked exactly the way he showed exactly that's what makes sreetips the best by far
I guess leaving an organic molecule like DMG in solution for too long will trigger some kind of redox reaction, which will reduce the Ag+. and God knows what Pt or Pd, which are often used as catalysts, will do to organic molecules over time.
I wonder if that was actually silver, or if it was somehow metallic palladium? I mean, the two metals look very similar. I’m not sure HOW exactly anything got reduced to metal like that but just something I thought might explain this a bit better maybe.
This who thing was full of problems. I’ve still got some of those solutions in beakers sitting my shop. I’ve lost my edge. Getting too old to make bold moves like I used to.
Do you take notes on how each experiment goes and try to improve/streamline the process for stuff like the stockpot series or gold filled/gold filled inquartation experiments?
wonder if the paladium can be enquarted with the silver similar to what you do with the gold and be purrified with other acids that disolve the silver but not the paladium...
Question: With respect to silver cementation, does it matter if the copper tube is left to rest on the bottom of the beaker or should it be raised as to not be covered by the cemented silver. Or does it not matter at all. Just curious if its a surface area exposure thing or just as long as the solution is in contact with the copper. Thanks in advance!
Way too much silver in solution to chase other metals and it’s still green when u put copper in I would of started by chloride the silver to clean all other metals from it and chased them in the stock pot/ zinc/copper later idea is to get clean silver to run again through cell
Not exactly the best situation with the silver palladium, but I would imagine if you were to melt it up into shot and run it thru the silver cell it would probably remove the silver and leave behind the PMGs.
@@apveening I was under the assumption that the silver cell results in pure silver while leaving behind the platinum group metals in the filter basket. Though - I made the comment before seeing that there was far less silver than PGM in the mud. In the beaker it looked like there was a pound of silver because it was lining the glass.
@@cracklingice The silver cell results in three nines fine pure silver, meaning it is at least 99.90% silver, pure enough for all practical standards to be called pure. However, that remaining 0.10% is for a large part palladium followed by other valuable metals (including silver, it is probably something like 99.95% pure).
That’s ok, any palladium will cement out on the copper. Then we’ll run it through the silver cell again. Those PGMs are very uncooperative. You can never get it all. And you can never get a 100% separation.
@@sreetips Yes ofcourse it won't be lost, but I thought it would be better to get as much Palladium out of the waste stream as possible beacause it will reduce work, time and recources. I would have done a second DMG percipitation. The deep dark green colour was ofcourse a hint. I get it that there was probably also some coloidial PGM in there that made the colour so dark. I really like these vids. It also puts the brain to work again to follow what's going on. Very curious what the yields will be.
Found a video that used a clip of a video of yours. Channel is “Factora”. Video is called “ How GOLD is made.” Shows your clip starting at the 4:34 mark in the video.
They undoubtedly found a clip that didn’t include my brand. They’re all over the internet. Someone always looking to get something for nothing. One TH-camr had all 56 of my videos re-uploaded to their channel when I first started. Even the one of my wife receiving her 36th wedding anniversary. This is the world we live in. Thank you for pointing it out to me. This is why branding with my name plastered everywhere is so important. A giant pain to have to do it.
Would redissolving (the palladium/silver precipitate) with Nitric Acid, and re-precipitating the palladium with DMG work? Edit: Teach me to comment before I watch the whole video! *laughs*
Hello sir @sreetips I watch and followed you for awhile now and one time I decided to recover gold from computer ram as gold fingers but when i finished my first recovery and tried to sell the gold recover they say that the gold recovered from aqua regia is not pure, can you give me any advice why is it not pure as yours?
That makes me wonder if converting it to silver chloride might make it easier to separate. From a brief glance at Wikipedia, palladium will form a chloride, but it needs aqua regia or dissolved chlorine gas to really do that. PdCl2 also dissolves better in cold water, whereas AgCl likes hot water. PdCl can also be dissolved in organic solvents. If what you're doing now doesn't work, maybe try ice cold HCl to extract the Pd. Or listen to someone who actually knows what they're doing, that's not me lol.
@@sreetips acctualy it work. Sometimes we have different type of particles of gold pgm ect that will react different. So always have to make a test and see. This is what you did

I want to see how much palladium and platinum he is able to melt love these vids
There won't be much...
@@mattgraham1983 who cares how much I live watching and learning how to do this sreetips knocks them out of the park each time great education video's real to much fake crap out there and I'm tired of lies and false hoods
@@brianevans1851who's videos are you watching that are "fake"???
@@PaulBrown-uj5le there foreign and a few that are American when I first started watching these 4 or so years ago the first time I watched they made the claim about how much gold they refined from scrap computers and gold plated jewelry it showed some of the process but not all and at the end they claimed they got 12 gram or a 5 gram button from only one bag of plated material back then I thought it was honest so I started saving and buying boy did they fool me
@@PaulBrown-uj5le I enjoy this I had gold that my grandpa gave me for years from his claim in Arizona every place I took it tried giving me far less than what gold spot was so I started trying to learn how to refine it I had lots of nuggets and flakes but they all said it was not pure gold so I held onto it and tried many times to refine I was about to give up when I saw a sreetips video that's when I knew I was hoaxed about gold plated then I seen the one he did of nuggets of gold and the fact it's better to incorporate silver in the process I've been watching sreetips ever since it worked exactly the way he showed exactly that's what makes sreetips the best by far
I guess leaving an organic molecule like DMG in solution for too long will trigger some kind of redox reaction, which will reduce the Ag+. and God knows what Pt or Pd, which are often used as catalysts, will do to organic molecules over time.
Could you use a stronger vacuum? Or can you tear filter papers or something equally undesirable?
Can’t get any higher vacuum than 29 inches of mercury.
Just kinda curious will you ever collaborate with any other TH-camrs? Thank you so much I’m a loyal watcher of your content.
One day I will.
I wonder if that was actually silver, or if it was somehow metallic palladium? I mean, the two metals look very similar. I’m not sure HOW exactly anything got reduced to metal like that but just something I thought might explain this a bit better maybe.
This who thing was full of problems. I’ve still got some of those solutions in beakers sitting my shop. I’ve lost my edge. Getting too old to make bold moves like I used to.
Do you take notes on how each experiment goes and try to improve/streamline the process for stuff like the stockpot series or gold filled/gold filled inquartation experiments?
The only notes are the videos.
Yup missed the first part, I think I have it now ty
If you make siver chloride then filter you get the silver out
As long as all traces of nitric acid are gone, that's kind of what I was thinking.
I would have checked the ph levels to prevent the silver from coming out of solution and joining the palladium
I should have filtered the Pd precipitate immediately. Leaving it sit overnight is what got me.
As usual another fantastic video, looking forward to the next one ty sreetips 👍🏻
Thx for the video! Have u considered processing hard rock miineral??
No
Keep up the hard work❤💪!
wonder if the paladium can be enquarted with the silver similar to what you do with the gold and be purrified with other acids that disolve the silver but not the paladium...
Easier to do it the other way around (dissolve Pd and leave the Ag as a solid or salt).
Palladium is soluble in nitric. The only one of the six sister metals (platinum, palladium, rhodium, iridium, Osmium, ruthenium) that is.
always a great video!
I cant wait to see your video buddy
Whew almost a disaster but in typical sreetips grace you pull it out excellent video six stars sir
Question: With respect to silver cementation, does it matter if the copper tube is left to rest on the bottom of the beaker or should it be raised as to not be covered by the cemented silver. Or does it not matter at all. Just curious if its a surface area exposure thing or just as long as the solution is in contact with the copper. Thanks in advance!
Best to submerge it in the silver solution completely.
A learning curve for all
Thank you!
When I make my first million from poker, I’m putting together a pro grade lab and hitting the yard sales
Good save with the DMT solution.
DMG*
Oooof. Good luck....
I wonder what is gumming up that filter so badly.
Sreetips @ 2:05 You need to invest in some separatory funnels.
Great channel 👏
That tortuous filtration is hard to watch, but I assume putting highly acidic liquids in a centrifuge is probably not the best idea.
ever try lighting those filters on fire? basically old fashioned gun cotton right?
I try to get all the nitric rinsed out with water.
Way too much silver in solution to chase other metals and it’s still green when u put copper in I would of started by chloride the silver to clean all other metals from it and chased them in the stock pot/ zinc/copper later idea is to get clean silver to run again through cell
Hello Sir, so, plot twist on the way, I am sure, we will learn something new...
To remove the silver coating on your beakers, do you just boil a little nitric acid in them?
Yes
Not exactly the best situation with the silver palladium, but I would imagine if you were to melt it up into shot and run it thru the silver cell it would probably remove the silver and leave behind the PMGs.
The Pd has a tendency to follow Ag.
@@apveening I was under the assumption that the silver cell results in pure silver while leaving behind the platinum group metals in the filter basket. Though - I made the comment before seeing that there was far less silver than PGM in the mud. In the beaker it looked like there was a pound of silver because it was lining the glass.
@@cracklingice The silver cell results in three nines fine pure silver, meaning it is at least 99.90% silver, pure enough for all practical standards to be called pure. However, that remaining 0.10% is for a large part palladium followed by other valuable metals (including silver, it is probably something like 99.95% pure).
There’s 400ml of solids in the beaker. It looks like a lot. But in the end it will only yield a few grams.
I'm pretty sure there is Paladium in the solution you threw the Copper pipe in. It will plate out now. You had to test it for Paladium.
That’s ok, any palladium will cement out on the copper. Then we’ll run it through the silver cell again. Those PGMs are very uncooperative. You can never get it all. And you can never get a 100% separation.
@@sreetips Yes ofcourse it won't be lost, but I thought it would be better to get as much Palladium out of the waste stream as possible beacause it will reduce work, time and recources. I would have done a second DMG percipitation. The deep dark green colour was ofcourse a hint. I get it that there was probably also some coloidial PGM in there that made the colour so dark. I really like these vids. It also puts the brain to work again to follow what's going on. Very curious what the yields will be.
Excellent.
Please make silver ingots at the end 🙏
هل اصتدام النحاس الأحمر المنصهر في الماء على لوح خشبي يزيد وزن النحاس ارجو الرد 😮😮😮😮
No
Yes sir even before i see your video it sure does you can mistake silver for pt metals
Found a video that used a clip of a video of yours. Channel is “Factora”. Video is called “ How GOLD is made.” Shows your clip starting at the 4:34 mark in the video.
They undoubtedly found a clip that didn’t include my brand. They’re all over the internet. Someone always looking to get something for nothing. One TH-camr had all 56 of my videos re-uploaded to their channel when I first started. Even the one of my wife receiving her 36th wedding anniversary. This is the world we live in. Thank you for pointing it out to me. This is why branding with my name plastered everywhere is so important. A giant pain to have to do it.
Glad to help. I imagine making videos is quite a bit of work. They are your product and someone is using them without permission.
Would redissolving (the palladium/silver precipitate) with Nitric Acid, and re-precipitating the palladium with DMG work?
Edit: Teach me to comment before I watch the whole video! *laughs*
I'll be looking forward to the next , thank you Sreetips 👍👍
You might want to precipitate the silver before the palladium
My rabbit sat through the whole thing. Maybe i can get him to help me refine silver 🤔
Part 2 Cliffhanger.
Couldn't you just boil it in distilled water, metallic silver is insoluble in water where as salts are.....
Possibly
Hello sir @sreetips I watch and followed you for awhile now and one time I decided to recover gold from computer ram as gold fingers but when i finished my first recovery and tried to sell the gold recover they say that the gold recovered from aqua regia is not pure, can you give me any advice why is it not pure as yours?
It must be refined to get pure gold. Recovery and refining are two totally different processes.
@@sreetips Thank you sir for answering my questions and giving free lessons here in youtube hope you still healthy and more blessings to you 😇😇😇
Would a change in the ph level make the silver drop out of solution?
Don’t know
That makes me wonder if converting it to silver chloride might make it easier to separate. From a brief glance at Wikipedia, palladium will form a chloride, but it needs aqua regia or dissolved chlorine gas to really do that. PdCl2 also dissolves better in cold water, whereas AgCl likes hot water. PdCl can also be dissolved in organic solvents. If what you're doing now doesn't work, maybe try ice cold HCl to extract the Pd. Or listen to someone who actually knows what they're doing, that's not me lol.
Y put dmg filter onto hot plate with nitric it will disolve silve and palladium
Because that’s what I thought would work
@@sreetips acctualy it work. Sometimes we have different type of particles of gold pgm ect that will react different. So always have to make a test and see. This is what you did
