How To Recover Palladium From The Silver Solution

[@Alondro77]

One little note: careful about adding ethanol to nitrate metal salts. If the concentration gets too high, it can result in the formation of FULMINATES... and if they dry and start to form crystals... they tend to like to explode violently if you so much as look at them the wrong way.

[@westcoast8562]

Sounds like fun

Beavis' voice: "Fulminates! Hehehehe! Yeah, FULMINATES!"

[@TheRealWeirdoC]

Came to the comments immediately upon hearing "alcohol" to see if anyone else had already given the fulminate warning.

[@AndyGraceMedia]

Great comment! A very young Explosions and Fire's KZbin channel has a good video about silver fulminate from years ago well before he really went off the deep end (in a good way). Chemistry nerds: it's a MUST watch channel if you haven't seen it.. He's kind of the Wicked Witch of the West to sreetip's Good Witch of the East.

[@Antonowskyfly]

You are welcome. A quick and easy demonstration of precipitating the mischievous noble metals that are downright difficult to refine. Thank you Sir!👍👍🤟

[@someguy-k2h]

I was going to say that before you added the DMG, that you should adjust the Ph to around 7. That would stop the Pd from dissolving back into solution, and allow you to cement out the Ag must easier.

[@sreetips]

I usually add more sterling silver and let it simmer to remove excess nitric before I try to cement the silver on copper. No worries, that solution may have enough nitric to completely dissolve the piece of copper so I may need to add more copper in the morning.

[@thorild69]

In the reactions, the color is often an indicator. In the videos, it is very pretty. Thanks as always.

[@redbaronrefining5322]

Quick tip: you can use a pinch of sodium hydroxide and a bit of heat to get the DMG to fully go into solution. Learned this trick and it’s saved me time from having to smell that “throw-up” scent that comes off it when stirring with just water to get it into your filtrate quicker under the fume hood. 😊

[@carlherrnstein9544]

Careful with adding alcohol to the silver nitrate, if I remember correctly that can make silver fulminate, possibly adding salt would stop the reaction.

[@ArielleViking]

Very interesting getting those platinum group metals out of the silver solution without any silver. 👍🏻

[@barthanes1]

The reflected logo was a nice touch.

[@jamescball55]

I was going to suggest using 70% isopropyl alcohol with your DMG. Ethanol seems to work too though.

[@thorild69]

The convection flow from the excess nitric is mesmerizing.

[@psychodermix]

Possibly the most interesting one you've done so far. Loved it.

[@untermench3502]

There are some who suggest precipitating the Silver first as AgCl, then dealing with residual PGMs.

[@sreetips]

@untermench3502 lazersteve used to say that. And I believe it’s probably the best way to go.

[@Sanzus2]

The runaway cement silver reaction was a first! Let us know how long that reaction goes! Always interesting when you do something new, that was definately a new one!

[@josephcormier5974]

Excellent video sir very enjoyable thank you for sharing this with us six stars sir

[@Ellis157]

Just a thought. Would you be able to skim the very surface of the beaker and get that palladium salt that's floating on the tops? Can you. basically use one of your filter papers to do it. and just add that to the process of whatever

[@CothranMike]

Yes, skim of float is common, overflow of float is very common industrially -in fact several processes create float, aid its formation and add air to get it up and over the edge for further processing.

[@sreetips]

Possibly, but there’s such a tiny amount that it’s not practical.

I'm wondering, which metal takes you a long time and bothers you about: gold, silver, platinum, palladium? I learned a lot of information thanks to you. Your speaking style is very good, I am improving my English thanks to you.❤❤❤❤❤

[@sreetips]

Excellent, thank you. Gold is easiest. Silver is next but takes days to refine in the silver cell. But those two are like a cookie recipe compared to PGMs. Of those, palladium seems to be the easiest. Next is platinum. The four in the platinum group (rhodium, iridium, osmium, ruthenium) are an enigma to me.

Why working on such high volume of liquid (dilution level) when you have small concentration of precious metal? I suggest burn excess water and work on the concentrate for better precipitation and removal of metals. Also you paper test with stannous will be more effective. Nice video for separation.

[@lamarkelsaw8923]

Why haven’t you done more 5 9’s FINE smelting? Will you ever melt platinum bars? Too dangerous? Love your channel, Man!!!

[@CothranMike]

He never has done smelting... check your terms, they mean things different than you intend them to.

[@sreetips]

CothranMike is right, smelt is a term used to describe rendering metals from ore. I’ve melted five nines silver. Platinum has a very high melting point up over three thousand so pouring a platinum bar with my crude setup probably won’t happen.

[@apveening]

@@CothranMike Probably not a native speaker of English, English is one of the few languages I know (and the only Germanic one) that makes a distinction between melting and smelting.

[@jacobpalane9462]

Mr Sreetips, do you perhaps know a way to precipitate Rare Earth Element (REEs) in Nitric acid medium?

[@sreetips]

I can precipitate gold, silver and platinum group metals. And iron, with sodium hydroxide.

[@stevenbriggs784]

No way! wow, I just found a ring from the early 1900s with pure palladium prongs holding an old hand cut rose diamond. I took it to 8 jewellers, ALL of them had no idea what palladium was, they'd never heard of it before, not even as an element. THAT is how rare it is now days! This was in Perth mind you, a prestigious, High end Australian city where more educated men than me work and live! Thanks again, Sreetips!

[@someguy-k2h]

I don't know where you live, but the "jewelers" around you aren't very smart. Anyone working in precious metals should know their craft better than that.

[@stevenbriggs784]

@someguy-k2h it's just not common and hasn't been for quite some time.

[@someguy-k2h]

@@stevenbriggs784 Nobody said it was common. I said it was precious. The job of a jeweler is to craft precious metals, and gems. At least everywhere else, that' the job.

[@stevenbriggs784]

@@someguy-k2h I say its not common anymore to imply the reason as to why some jewellers dont work with it, precious or not. I agree, it is their job to work Jewellery, but what its made up of is up to the person, it cant be expected that all jewellers will know about all alloys available, and that wouldnt be a reason to judge their skills. i dont expect most jewellers to know what palladium is, because theyll probably never come across it :D its rare, and that being my point, im glad youre aware of it. you must be very well educated on the matter.

[@aleksandarcarkic8958]

Maybe i missed something. How are you sure that the precipitated complex with DMG is only a complex with palladium? Isn't white gold also made with nickel, which again with DMG gives a complex compound, that is a precipitate?

[@sreetips]

I don’t know how to tell.

[@aleksandarcarkic8958]

@@sreetips First of all, thanks for the no answer ;))). That made me remember a little of the student exercises, when we were proving divalent nickel with DMG. The nickel deposition reaction takes place in an alkaline environment (ammonia). Deposition with yours is in an extremely acidic environment. Any nickel present remains in solution. Thanks again, and all the best.

How do you dispose of your waste liquids when they’re completely barren of precious metals?

[@sreetips]

Waste treatment.

[@redbaronrefining5322]

Definitely had excess nitric. If you don’t have the time to run the silver through the silver cell or want to get the palladium quicker, you’d have to denox. Problem is silver hates to be denoxed, so you can use some hcl to precipitate the silver first into chloride, filter and rinse, then use copper to cement out the pd or a little more costly and use the DMG.

[@sreetips]

I prefer adding sterling and simmering until all the nitric has been consumed.

[@hobbiesrus]

I am curious if you have accumulated lead from all your refinings and how you deal with it, if any, at the end.

[@sreetips]

Lead should get precipitated as insoluble lead sulfate from the sulfuric acid that I add. Then filtered out.

[@hobbiesrus]

So those filter papers get tossed as opposed to going in paper storage. You have such an excellent waste and recovery management system that it is hard to imagine you tossing away anything you filter!

[@sreetips]

I save all my filters, lead included

[@wayneneher6362]

What is it that makes the gold white? I thought it was nickel.

[@13Nagash13]

The cheaper white gold adds nickel, but the expensive stuff adds platinum/palladium.

[@sreetips]

Yellow karat gold is an alloy of pure gold, silver, copper and zinc. To color it white, the amount of copper is reduced or eliminated and replaced with more white metals including palladium.

[@puellanivis]

200 proof alcohol! :O One of the few proofs of alcohol that don’t need alcohol consumption taxes-not because it’s denatured, but because it’s so expensive to produce, that it would just be dumb AF to drink it, rather than use it in a lab environment. (The azeotrope of water-ethanol is around 96% by volume, at which point, you cannot distill it any longer to remove either water or alcohol. To get you over that hump, you need another way to remove the water, which is a pain. So, distillers making alcohol for human-consumption just don’t bother. Only chemists ever need it more pure.)

[@carlherrnstein9544]

If you want cheap 200 proof, get a bottle of 190 and dry it with fresh calcium oxide, it'll pull the remaining water out of it. Just remember that it will pull water out of the air.
