Stock Pot Six Precious Metals From Waste Pt4

[@LOT9T]

I mean most refiners just go for the gold wasting gram after gram like it is a flex! MR. Sreetips scratches, scrapes, precipitates, and filters every possible precious metal available. Meticulous indeed! It is why i am here folks! Always enjoy the process!

You’re welcome. This is an excellent, clear and concise update to the progress made so far. Thank you Sir!👍👍🤟

To extract rhodium, it is first converted into a more soluble rhodium compound. This is often done by reacting it with hydrochloric acid (HCl) to form rhodium chloride (RhCl3).A method for purifying rhodium, comprising dissolving and removing coarse crystals of ammonium chloride, heating the obtained rhodium-containing crystal in water and then cooling to recrystallize rhodium.

[@scienceisthewaytogo8645]

Wow, PGMs seem like an absolute pain in the ass. Maybe we can just all agree that they aren't precious so people don't have to go through this sort of pain retrieving them?

Looks like you need to build a bigger fume Hood because this video shows you don't have a lot of room to work around with.

Bigger fume hood would be awesome.

[@ut000bs]

Didn't you have a few pieces of white gold? I remember at least one. That is where rhodium could have come from. I broke down and bought one each, 1oz. US Palladium Eagle and Platinum Eagle coins a couple of years ago "just because" I wanted to have something PGM. Can't see stacking either one because it would be harder to get value for it if everything turns upside down. If I ever sell any of my metal those two coins will be the first. A gram of rhodium is currently over $150.

[@zachreyhelmberger894]

Separating platinum from palladium and rhodium sounds SUPER hard to do...

[@sreetips]

Palladium is the easiest because it’s soluble in just nitric acid. I’ve done platinum but it’s too dangerous for the hobby refiner. The other four in the platinum group (rhodium, iridium, osmium, ruthenium) are a complete enigma to me. Those who know how to recover and refine these metals want to take their secrets to the grave. They are not eager to share how it’s done. Especially with someone who will publish it on social media for all to see.

[@williamfoote2888]

@@sreetipsonce you’ve sorted the metals, in solution, you can precipitate each one with sodium borohydride. That’s the best you can do because you have no practical means to melt them into presentable buttons. Maybe isolated black powders are your end product. Oh yeah. And rhenium. FWIW, working with Pt at low concentrations isn’t risky. Os, At any concentration is risky, but it’s in so few products, you aren’t likely to ever see it.

[@tom23rd]

Aww shucks. No refine this go around 😅 guess I just need to chill and wait for next time. No worries, I understand the cost benefit doesn't really favor it here. 😉 Will be interesting to see what you come up with for the Rhodium.

[@nunotavares8707]

Mr. Sreetips, the book @Mike-d6b mentions, is a good start point to learn how to handle rhodium, and others. However, my advise, from experience, is to keep away from all the PGM's due to their toxicity, costs involved, and low yields. Sell the concentrate powders, like that broken button you have, and be done with it. A fully enclosed fume hood is highly recommended

[@SubaruOffRD]

[@ExtractingMetals]

I finally figured out what the blue solids are. It is copper oxalate CuC2O4. When heated it will break down into copper oxide CuO. At that point it will easily dissolve in HCL leaving the precious metals behind.

[@sreetips]

I figured it was some compound of copper. Good to know. Thank you.

I asked chat gpt “How do you detect for test for and refine rhodium from other platinum group metals” Detecting, testing for, and refining rhodium from other platinum group metals (PGMs) involves several complex steps due to the similar chemical properties of these metals. Here is an overview of the process: ### Detection and Testing 1. **Sample Preparation**: - Dissolve the metal sample in aqua regia (a mixture of nitric acid and hydrochloric acid) to bring the metals into solution. PGMs are resistant to many acids but dissolve in aqua regia. 2. **Separation by Precipitation**: - Different PGMs can be precipitated from the solution using selective chemical reactions. For instance, ammonium chloride can be used to precipitate platinum as ammonium hexachloroplatinate. 3. **Spectroscopic Analysis**: - Inductively Coupled Plasma Mass Spectrometry (ICP-MS) or Atomic Absorption Spectroscopy (AAS) can be used to detect and quantify rhodium and other PGMs in the solution. 4. **X-ray Fluorescence (XRF)**: - XRF is a non-destructive technique that can be used to identify the presence of rhodium and other PGMs in solid samples. ### Refining Process 1. **Initial Dissolution**: - As mentioned, dissolve the raw material in aqua regia to get all PGMs into a soluble form. Rhodium, along with other PGMs, will be in solution. 2. **Selective Precipitation**: - Precipitate platinum first by adding ammonium chloride to the solution to form ammonium hexachloroplatinate, which can be filtered out. - Palladium can be precipitated by adding dimethylglyoxime (DMG), which forms a complex with palladium. 3. **Solvent Extraction**: - Use specific organic solvents to extract rhodium from the remaining solution. Solvents such as tributyl phosphate (TBP) in kerosene can be used to selectively extract rhodium. 4. **Reduction and Purification**: - Reduce rhodium ions to metallic rhodium using a reducing agent like formic acid, hydrogen gas, or sodium borohydride. - Further purification can be achieved by repeated dissolution and precipitation cycles, or by using ion exchange resins. 5. **Electrorefining**: - Electrorefining can be employed to achieve high-purity rhodium. In this process, rhodium is dissolved in an electrolytic solution and then deposited onto a cathode by applying an electric current. ### Example Procedures 1. **Hydroxide Fusion**: - Mix the rhodium-containing material with sodium peroxide or sodium hydroxide and fuse it at high temperatures. This separates rhodium from other PGMs as it forms soluble rhodium hydroxide. 2. **Aqua Regia Leaching and Ion Exchange**: - After dissolving the material in aqua regia, use ion exchange chromatography to separate rhodium from other PGMs. Specific resins can selectively bind rhodium ions, which can later be eluted and recovered. ### Conclusion Refining rhodium from other platinum group metals is intricate and requires careful control of chemical reactions and conditions. The processes outlined are general steps; specific methodologies may vary based on the composition of the raw material and the desired purity of the final product. Safety precautions must be strictly followed due to the hazardous nature of the chemicals involved.

Hi sreetips I have a question, I was sometimes getting headaches after eating, recently I noticed a dark soot that had bonded to the bottom of my aluminum pot. I think when I had double boiled something (chlorinated tap water) with these smaller portion sized aluminum pots, maybe not aluminum, but look like it. The bottom of the small pot looks normal, big pot dark soot I had to scrub off hard. I think the small pots are Chinese made, maybe not pure aluminum, blended w pot metal, any guess what it may be? Thank you!!

[@sreetips]

No telling what it is.

[@mattroyle1087]

Hmm, ok, thank you for letting me bend your ear! After I cleaned I just boiled with tap water and the color appeared so I scrubbed it off again. Boiling again to see if it lessens, I think something leeched into the aluminum, hopefully I can get it all out. Not a science experiment I wanted... Thanks for the great vids always!

Only thing that could have been better is if you would have given a weight of the black powder that was recovered with zinc.

[@StefanShorko]

I got a question sreetips. Can you dissolve cigarette butts (made out of cellulose acetate) in nitric acid? I assume yes. But if you can, what by product do you get from it? And how do you safely pour all these acids in the natural environment, considering how toxic nitric acid is?

[@sreetips]

I’ve never tried to dissolve cigarette buts in nitric. There’s very little, if any, nitric acid in any of my waste solutions. It all gets consumed during the reaction.

[@StefanShorko]

@@sreetipsoh I see. So what does it turn into when you add sodium metabisulfite? Is it water?

I recently came across what looks like melted silver that may have gold in it. The guy who owns it got it from an estate sale. How can you test it to see if it is or not. Would the scratch test work? The silver looks like it's been melted and then dropped in water and has a brassish tinge to it. I know if I scratched it and tested it for silver it should turn red but how would you test it for the gold in it?
