this is the number one refining channel on you tube!! you have upped your game sir. thank you for sharing your knowledge and putting the effort in. i bet it can get overwhelming having to film your work. cheers.

[@judithyoungquist8409]

Absolutely enthralled by your vids! I’m going to go back to the beginning and watch from the beginning! Thank you so much for sharing with us!

[@sreetips]

I've got several more coming soon. I finally got some pure platinum metal last night. The video is uploading as I write this. I'm literally making it up as I go, and you can tell because I make a few wrong turns. Thank you.

[@MrDannyd9]

30:40 The same happens with gold. It is because the alloy metal creates interstitial space between the precious metal particles. Aqua Regia does its thing because it removes the oxidizes from the metal (with HCl); however, the alloy metal doesn’t allow the oxide to form, so the nitric can attack the precious metals without help from another acid.

[@dbaca148]

New to the refining process. Been watching all of Streetip's vids. Just ordered my first jug of nitric. So much to learn. Great lessons!

[@sirfartsalot1328]

Take it slow. If you can, get a copy of "refining precious metals wastes" by C.M. Hoke and read it over a few times. Take baby steps, have good ventilation, and be patient. Practice good personal safety because this hobby can kill you if you're not careful. Also, there are Facebook groups that are strictly focused on this hobby. They are a wealth of knowledge as well as the forums. Studying up before doing anything will help you understand what's happening before you start using acids and other hazardous materials.

[@catch22frubert]

Hey Sreetips! I just wanted to thank you for doing some refining of the platinum group metals. Not many people have done work with the platinum group, so it's much appreciated that you have done these for us. I'm particularly interested in the platinum group from a chemistry standpoint, because of their many cool abilities and uses in other important reactions as a catalist. It's also very cool that most don't oxidize and are stable for so long. So again, thanks for the awesome videos! I'll be patiently waiting for your next videos.

[@SK-yw5ih]

I love adding a little SMBV (Sreetips-Made Baller Videos) in my youtube solution before I settle overnight. Sreetips man, you are my favorite youtuber at the moment. Your depth of knowledge and content is so profound, and your presentation is extremely well done. While I'd love to try my hand at refining, it is so out of my comfort zone, I'm happy just watching a pro do it, because I simply don't have the nerves to handle glass beakers full of boiling toxic liquid acid solutions worth 1/10th of what you do. You've got nerves of PTFE!

Rolling on the floor laughing. The narrator says "adding sugar slowly to avoid boiling over", but the subtitles say deliberately provoking a boil over just to show off.

This video was SO much better than the program my wife was watching. Thanks!

[@markhirschmann9967]

Bit late to the party ,but having worked in a platinum refinery ,one way of dealing with the filters was to calcine them ,i.e incinerate them in a silica tray at high temperature just leaving the solids behind .Other than that I enjoyed your video

[@wadehampton1534]

Wonderful video, sreetips, and very informative. I'm glad I watched this, because I'm going to be setting up a silver cell as my entry into refining precious metals. I'm excited to see the palladium salts that came out of the slimes, and the little gold bead, fascinating. I'm off to watch PT. 2 and see how you turn that yellow powder into palladium!

[@mikeconnery4652]

It's the molecules, the molecules are so few that they are just released when the silver is desolved. This will also happen with your silver incortation of gold.

[@frankzahn7773]

You could have saved a lot of nitric by running the slug through a sieve and wash it before adding the nitric acid. Then add the silver to the next silver cell. Save some money.

[@readoryx373]

Beginner here, will ask anyway: could the stubborn black/silver residues been made more extractable by roasting at 600f for 45 minutes in between refinings, to oxidize stubborn bonds?

[@sreetips]

Possibly

[@shaneyork300]

I started watching the paladium refining videos and I wanted to see where the paladium originated!! Pretty dang good to get what I am guessing to be well over a thousand dollars after the paladium refine out of the silver cell filters!! Question:: I know you like to put myths about ewaste to the test, I'm would like to know if you'd consider doing an mlcc refine???? I laughed a little when I heard this because of the education I've learned by watching your vids! But I've heard from several ewaste KZbinrs (NOT REFINERS) that the older or vintage mlcc's have 80% silver and 20% paladium in them!! I immediately thought of you and how you'd probably like to BUST THAT MYTH!!!! 👍👍👍👍 Have a GREAT Day Sreetips!!!

[@krotos2009]

Love that sugar reaction with sodium hydroxide haha I cant wait to try it for my silver.

[@OwlTech333]

Hi! Thanks for the video! 6:34 I don't think the green colour of a nitric solution indicates palladium presence . In my experience palladium tends to colour the nitric solution brown - from "tea" to "cola" (depending on the concentration). Nickel is more likely to be the culprit of the green colour, but I could be wrong, Take care!

[@sreetips]

All the silver in this video was cemented on copper or silver chloride conversion. Either way there is no way for nickel to get into the silver. Nickel is higher up in the list than copper so it won't cement out on copper when the silver is being cemented. Nickel dissolved in nitric is green. Palladium dissolved in nitric with sterling silver will appear green due to the copper in solution.

[@OwlTech333]

I guess you could be right then

[@Enjoymentboy]

Excellent video, as always. I've thoroughly enjoyed the whole process but I'm left with a question: How many lbs of silver would you guess you've run through those filter baskets to get this recovery?

[@sreetips]

I can't remember the number of filters. Let's say twelve. Each filter had at least 1.5 kilos of cement silver run through it. So I'd estimate about (12 * 1.5 = 18 kilos). 18 kilos divided by 453 grams = about 40 pounds of silver - estimated.

Thank you Sreetips. These videos are very fun to watch and learn with. Personally I like these long ones. Thanks again.

[@davidtwining4059]

Those slimes are like money in the bank.

[@PrometheusZandski]

Just a fantastic process to watch. I was wondering why you didn't remove the slimes from the filters with hot water, then dry and weigh them. Then do a test run on a small amount. This would have allowed you to calculate concentrations of different precious metals, and better estimate the amount of Nitric and DMG needed.

[@sreetips]

I just didn’t think of it

[@PrometheusZandski]

@@sreetips You are a busy guy, you can't think of everything. Love your videos. Makes me feel like a real chemist.

[@anon0054]

Fantastic video! Amazing the amount of other metals in the silverware. Do you think this was done intentionally or was the silver just not purified when making the silverware?

[@sreetips]

Silver is a carrier of platinum group metals and gold, especially older pieces of silver.

silver jewelry may be coated in a thin layer of rhodium. Rhodium does not dissolve in AR. So you might have some rhodium in that black residue?

It was satisfying to see the whiteness of those boiled filters.

[@johannesdesloper8434]

I didn't watch it 100% but what I saw was a great video. Recently I made a video myself and was confronted with how hard it actually is to make something decent :D. Never thought of the almost inevitable editing studio.

[@Gday_Its_Will]

i love the long videos thank you mate

[@krzysztofkocierba8537]

Thanks Streetips, excellent guide. But tell me what you do with platinum whih was soluted with silver? Did you pour it into the sewage? It is better to pour leftovers into the stock pot and add some thin copper wire, which after a dozen or so days reduces the residual precious metal concentrated it to next refining. About silver reduction: 49:39 - left beaker the suspension is blue - it still contains copper. It is better to rinse thoroughly, until the test with ammonia does not give a blue reaction. You can have abuot 99.9% purity without again refining.

[@sreetips]

I add the platinum solutions to my stock pot. Please see my stock pot refining series. It's possible to get high purity silver the way you described. But the only way to be sure is to run it through the silver cell.

[@krzysztofkocierba8537]

In my job I use chemical refining silver, but ever before reduction I am testing silver chloride with ammonia for the presence of copper and nickel. It significantly reduces costs and time. Furthermore, I think that your Bach is great. I also remember him from childhood and I do not know what song it is. Probably a dance with some kind of suite, but ...

[@sreetips]

Rinsing the silver chloride until the ammonia test is clear from blue color produces lots of waste. But it does make some pure silver powder. What about the palladium? It's worth about 70 times more by weight than the silver. Silver is a carrier of palladium and traces of gold and platinum.

[@krzysztofkocierba8537]

You are right. Really big stockpot is a solution.;)

[@santababy1952]

I'd like to see a video of how you process the filters. It is so clear this refining takes so much time. I hope you count that into the price of the things you sell on eBay. You are an awesome teacher. Is this what your job is? Your videos are so much fun. Have you ever written a book on how to do this? I am retired and have a lot of time on my hands and I think I could really get into this! Like I said, you are an awesome teacher and I have already learned so much. I even guess how much gold in gram weight you had.

[@sreetips]

Laura, thank you. I'm a retired U.S Navy Engineer. Refining is my hobby. But I do work at a jewelry repair shop setting diamonds and replacing watch batteries a few hours per month.

[@santababy1952]

@@sreetips My father was an engineer and got his start in the US Navy long before your time. He was also a metallurgist earning his masters in that. He worked for Western Electric and seriously was a jack of so many trades. He, like you could invent many ways to make an apparatus he needed rather than go and buy a new thing that did the same thing which is why I definitely believe he would have been quite at home refining precious metals. I have always been a rock hound though professionally I was a nurse until an injury to my back brought on early retirement. I would love to apprentice along someone like you who has the patience and knowledge to go through so many steps and consume so much time to achieve such small quantities of precious metals, however I think by the time you finish making all your pure silver crystals you may be able to have a full brick of fine silver! As for selling it, I agree, the price is so manipulated for precious metals. So I decided to buy myself some silver and a few gold coins. I did some reading and have heard it said that you should have 20-25% of your assets in precious metals so indeed you are setting yourself up well for your future income stability. I love watching you work and though I know little about chemistry, I am learning good bit. Thanks for your ability to make it all so interesting.

[@Qwertypp10]

Great video :) Why are you using hydrochloric acid to precipitate silver chloride, instead of for example sodium chloride?

[@sreetips]

Because it's cheap and sitting in a bottle right there for me to use. Dissolving salt in water takes another step. Plus I learned it that way and it works nicely for me.

[@michael636336]

On your stockpot. Use Na2CO3 to precipate metal ions. CO3's are less expensive and less soluble than OH's.

[@GQSmooth00]

Great video as always Sreetips. One question, is there a benefit to melting the cement silver into shot for the silver cell versus using the silver power in the anoded basket on it's own?

[@sreetips]

I tried adding the powdered silver once and it created a problem. It was a long time ago. I think it clogged the filter.

Concentrate your PM waste solutions using a dehumidifier. You get distilled water 💧from the dehumidifier which you can use for your wash water.

€ 44.92 all that. I do not understand a lot of metals but you have left a little yellow. Is it pure platinum or mixed with gold? and to the being Spanish I do not understand you much except for some words and phrases and one hour is too exhausting although I have seen it whole. I have several doubts since I have planned to do that more for hobby than to earn a living, although you never know in the future. One that metal is the one that is connected to separate the metals and which metals are those that are aprobechan those of the water bowl or those of the outer filter? So if it is a cloth or simply filter paper to separate metals by electricity. I have more doubts but for a newbie I think it's better by parts. Thanks for your video.

Hi there; I have enjoyed your videos for quite a while now and thank you. I do have 2 questions about this video. first why did you not attempt to precipitate the platinum with sodium chloride, and then precipitate the palladium with chlorine? and second, isn't palladium salt extremely soluble in water? thanks for your time! matt.

[@sreetips]

I didn't try to precipitate the Pt because there was very little to get in the first place, trace amounts only. DMG makes palladium easy and it get nearly 100% of the metal as the bright yellow precipitate. It's easy to filter out and It's easy to wash with distilled water because it does not dissolve in water.

[@matthewmoffatt9934]

Thank you for your quick response! is it the brick red palladium salt that is soluble in water? I apologize, I am new to refining palladium and there is several ways to do it, I just would like to know the best way.

[@Sigersteds]

How come the Palladium is not dissolved in the Silver cell when eletrolysing your silver? As I understand Palladium is dissolved by Nitric acid. So when you use Nitric Acid in the electrolyte in the Silver cell why does the palladium not go into solution? Why does it stay solid enough to get cought in the filter?

[@sreetips]

Because when I make the electrolyte I ensure that all available free nitric acid gets consumed. I boil the electrolyte until all fume production ceases and there is a small amount of silver left in the bottom of the beaker. That way there's very little if any free nitric left to dissolve any Pd in the anode basket.

[@neilsaucedo8207]

I wonder if the low levels of Platinum is the reason it dessolves in hot nitric acid?

[@ewastegold6619]

What's the best way to get Palladium from MLCCs that have accumulated from scraping computer equipment boards? I'm pretty sure grinding them to a powder is a good start, but beyond that what chemistry route would you pursue? If you got them free, how many grams would you need to do a video about it? I use a floor scraping chisel to scrape the boards 100% free of components. Then screen or hand pick various pieces. The MLCCs are in all the small and really small bits that fall through the screen. I can send close up pictures of the material if that will help you estimate the concentration of valuable metal in the mix. Thanks.

[@sreetips]

Palladium is soluble in nitric acid, the only one of the six sister metals in the platinum group. Platinum, palladium, rhodium, iridium, ruthenium, osmium.

[@sreetips]

If it were me, I'd boil in dilute nitric acid until everything dissolves, cool, filter, then add DMG to precipitate out the palladium salt. Filter the Pd salt washing well with distilled water and refine the salt to get pure palladium. With the Pd removed, cement the silver on copper and refine it in the electrolytic silver cell.

[@readoryx373]

[@TechneMoira]

I was wondering... you extracted several precious metals, among which platinum and gold from silver sludge. Can we assume that silver ALWAYS contains a little bit of gold, since gold will readily form an alloy with silver? As for the platinum forming an "alloy" with silver, I've read that Platinum can bind with Chloride in a specific chemical reaction to form Pt(NH3)2Cl2. When Silver Chloride and a small amount of Nitrates is added (in the form of Nitric acid), a complex chemical reaction seems to occur where there is a transitional form of platinum and silver. My chemistry knowledge is buried deeply, but I suppose it's a kind of Redox reaction. Some of the byproducts of this reaction seems to be compounds with the chemical names cis-[pt(NH3)2(H2o)2](No3)2 and AgCl. That's as far as I can take it. Since I'm not a professional chemist, nor a professor in Chemistry, I'll leave it to people far smarter than me to explain the chemistry behind these reactions :) It seems the Platinum complex described above, is something used in new cancer treatments by the way. Anyway, thanks for the video, as always very entertaining and instructive.

Silver is a known carrier of platinum group metals and gold. Especially older silver pieces made back in the day when reagents weren't as good as they are today. I bought an old silver cup weighed 750 grams, not marked, nobody wanted it so I dissolved in nitric and got over a gram of gold from that one item.

@@sreetips minus the cost can this be scaled to a profitable business model? Or not for the average person I ask as a scrapper who has hoarded e waste and love the thought of processing but even the I.c chips seems to be where chems could cost more then recovery any ideas or tips would be amazing be safe and God bless

Sir if copper silver and palladium is present in nitric acid and we don't have DMG then palladium should be separated somehow.

[@sreetips]

That’s tough one. I guess you could eliminate the silver by adding HCl to form silver chloride. But separating copper and palladium, both are soluble in nitric. Maybe cement copper and palladium on pure zinc. Then boil in sulfuric to remove the copper. But I’ve never tried it so I don’t know if it will work.
