Congrats, I must respect that all the refined platinum will fit in a 2 car garage, so I think understand the value of the knowledge it takes to produce it. With the knowledge comes the responsibility of handling danger close chemical reactions. This procedure will work on a much larger amount of material, thank you professor.

I hate, hate, hate refining the Platinum group metals! Though i had to learn to do it as part of the business, i nearly never refine any unless it's absolutely necessary! I get it isolated from other solutions and drop it with zinc. I then clean the zinc drop up with hcl til the metal is about 99%. That's Platinum black and as far as i go with it. The metals in the PGM group are such a pain in the ass to refine, unless you are dealing with a lot on a full time basis it's not worth it financially, but knowledge wise it is an asset. Business model wise mine comprises about 70% gold processing and 30% silver. Lou does all my PGM metals!

Have you considered using a centrifuge to separate your precipitates instead of filter paper?

Great class.please tell me how many catlitic did you use to gey the 21 grams of precious metals or an average precious for each converter?than you

For the 174ml, being 20ml per gram, is that particular to one or the other you add? HCL or peroxide or the combination of both? is there a ratio of acid to peroxide? I suspect if too little acid is used to too much peroxide surely the platinum wouldn't be fully dissolved?

How do I extract platinum group metals from ore and then how do I precipitate them. I have read some different things like crush pan roast pan dissolve in AR then precipitate each specific metal using different chemicals. Which chemicals are used to precipitate rhodium platniun and palladium I am about to start getting ALOT of VERY high grade ore containing gold silver platniun palladium and rhodium as well as some of the base metals.. any help would be appreciated.

Refining platinum is nothing like gold or silver. It's much more dangerous. A fume hood is an absolute must. Platinum dissolved in acid forms a compound that is of the highest toxic skin sensitizers known. you would be better off finding a reputable refiner to do it for you. Or just sell it as-is.

A fantastic series you've produced here. Many thanks. VERY educational. In fact I think I've come to the conclusion that Pt and Pd are just not worth the effort for me. I'll stick with Au/Ag. But this does leave me with a problem that I'm not sure what is the best way to proceed. I have a little under 300gm of Pd salt I dropped with DMG. Rough calculation would tell me around 90gm Pd so definitely not something I can just let sit and forget about.. All filtered and dried but still just sitting there. I'm really torn as to how best proceed. Should I calcine or redissolve in AR? Should I do the HCL & H2O2? What about dissolving in ammonia? I'm THINKING about dissolving in HCL and H2O2, filter the life out of it and then drop with zinc. Wash with HCL and then what is left "should" be pretty pure. But I'm so fart out of my comfort zone here and I think I just don't have anywhere near enough experience to delve into these metals.

@sreetips

5 жыл бұрын

I've done this material. I dissolved in AR and experienced runaway reaction that spewed hot acid everywhere. Once the salt was in solution I cemented the metals out on zinc - there was much platinum in that material as well because the DMG brings down platinum as well. Once cemented and excess zinc removed with HCl, I dried the black powder to get a weight then dissolved in HCl and h2o2 to achieve a solution that was 1 gram of the black powder per 20ml of solution. Then I added ammonium chloride to drop the platinum. I filtered out the platinum salt and bubble chlorine gas into the palladium to convert the palladium to ammonia soluble salt of palladium. I dissolved the brick red ammonia soluble palladium salt in 10% ammonia, filtered, and reacidify with HCl to get the beautiful canary yellow pure palladium salt. Then burn the canary yellow salt in a fused Quartz dish. I'd love to get my hands on that much Pd salt, it would make a great video!

Thank you very much. This helps. The bulk of t he Pd has come from scrap electronics so I don't think the Pt content would be high enough to warrant the full processing, and frankly the idea of platinosis is enough to keep me away from messing with it. But what a world we live in when Pt contamination is an actual problem to be overcome. :)

@sreetips

5 жыл бұрын

When refining palladium, ammonium chloride must be added, even if no platinum is suspected. The ammonium chloride facilitates the production of the brick red ammonia soluble palladium salt during the chlorine bubble. No ammonium chloride and the chlorine bubble won't work. That's when I discovered that DMG will drop platinum (not a well known fact in the refining community). Since it was palladium dropped with DMG I thought that ONLY palladium would be present. But when I added the ammonium chloride I was astonished to see platinum precipitating, a lot of it. There is no substitute for experience. If you want that palladium done right contact Lou Britton at aurisnoble.com located in Akron Ohio. He is an expert in PGM refining and he'll treat you right - no rip-off worries.

@@sreetips from "autocatalystmarket.com/us/en/articles/which-catalytic-converters-have-the-most-platinum" For many years, platinum has been the most valuable metal in a catalyst. There were times when it cost five times as much as palladium. But since 2015, the production of diesel vehicles has dropped significantly. This triggered a drop in platinum prices. If earlier this metal cost $ 2.2 thousand per ounce (about 31.1 grams), then in recent years it has been estimated at $ 600-800. In turn, precious metals used in gasoline cars have risen in price. Thus, the prices for rhodium in recent years have grown from 1.5 thousand to 12 thousand dollars per ounce. that price for rhodium sounds impressive...

I have a gulf ball size round piece of metal .it is platinum I believe. It weighs about 1 and three quarters of a pound . It is very heavy for it's size ....probably because it has been smelted so it is more pure and it is about the right density about 21 .Now the native or natural platinum nuggets I have are about 14 in density .. .the loss in density is probably due to the other base metals and other pgm's in them. My question is this,...the ball I have that has been smelted, do I have to smelt it again to make it even more pure, or is smelting it once enough .
