Back in 1995 I headed up a project to replace Pd in MLCCs with Ni. Pd was then about $75 / t.o. Did calculations on how much the project would save the company if Pd went up to $100 and even 150 / t.o. We went ahead and completed in 2001. Saved the company 100s of millions of dollars per year.
Can you make videos on how to recover indium and gallium? They are scrap metals, but there are no videos on how to recover them and their price is acceptable, especially for people from developing countries
Great video. Couple of thoughts to get a higher purity button. After converting Ag with HCl to AgCl and filtering, what about adding a few ml of 98% sulfuric acid to precipitate any remaining Pb. Have you thought about using Zn to precipitate the PGMs instead of formic acid? I've found changing the Ph of acidic solutions to be too time consuming. Looking forward to your next video.
Great video, just question, why donť you precipitate lead with sulfuric acid and filter to remove lead? It is used when purifying gold, is it different with PGMs? There was quite a lot of lead on XRF analysis... Just curious...
I didn't use H2SO4 back then, instead I used sulphamic acid , but didn't have any. It was a recovery process anyway that't why i didn't bother melting in a dirty crucible.
@@OwlTech333 OK, so get all the precisious metals, clean later (or sell as is...), legit... As I have heard, purification does not increase the price so much or not at all...
The video was shot a couple of years ago, only edited and uploaded now at that time I didn't grind the ceramics Wich resulted in longer processing time.
مرحبا عمل رائع جدن هل يمكن صهر المكثفات مع الرصاص الوحده فقط بدون فضه ومن ثم تبخير الرصاص بل البوتقه الاسمنتيه والحصول على البلاديوم تستحق تقدير والمتابعه والاحترام
Hello OwlTech, I can see after the first "burning out" you always use high temperature smelting. I'd like to avoid this and was wondering if a "wet process" e.g. by dissolving the burnt capacitors in nitric acid or nitric acid / hydrochloric acid mixture could be used as well. Basically dissolve everything then selectively precipitate what you are not interested in then the PGMs. I would like to use the PGMs as catalysts hence not interested in producing a nice Pd/Pt ingot or medalion in the end. :-) It seems you have quite an extensive knowledge about these things, maybe you know a few things about the wet process as well. By the way, I'm curious why those old ex-Soviet capacitors contain so much PGMs? Thanks!
Szerintem ha megfelelően pici a szemcseméret elkerülheted a megolvasztást. Én is katalizátor ügyben vagyok itt, tökéletes volna finom por formában is csak arra nincs megoldásom, hogy mindenféle egzotikus reagens nélkül elválasszam a platinát a palládiumtól, valami ötlet?
I'm just curious on "dropping" metals from solution using SMB, and other's like you use. What exactly is dropping the metals? Is it just reducing the PH of the acid, or is there a real reaction going on to create the metallic forms thus "dropping" them from solution? If it really is just reducing PH wouldn't you be able to use like baking soda, or even water? Been a little confused on the chemistry of the formation of the aqueous solutions back into their metallics.
For a metal to be in solution means that it has donated electron or electrons becoming a positively charged ion. In order to get it out of solution, or to "drop" it, the ion neeads to accept electron or electrons. SMB, and other precipitants give the electrons to the metallic ion so it becomes atom and drops out of solution.... The way I see it
@@OwlTech333 okay okay, so you need to dump in a negatively, or a reactively (-) charged substance to drop it out if I'm understanding that correctly. So in SMB it is the bisulfate (-) that actually does the work, and the sodium which is (+) doesn't do much. Thanks for the very insightful reply, and wanted to say I thoroughly enjoy your "outback hands on" style setup there. Especially using concrete as a cupel for example. So cheap, yet seems highly effective. Great stuff, and thanks again! (Let me know if I have that twisted, or backwards. Lol)
@@OwlTech333 So what I am reading is sodium carbonate should do the trick. It is also -2 valency just like SMB really. Unsure if the charge is the only factor, but it seems from our description that it works. Why would people use anything else with the prices I wonder?
Спасибо за ролик, отличная работа 👍 и с возвращением, отдельное огромное спасибо за русские субтитры, мой англиский далеко от совершенства 😁 Будь здрав!
We watch all that and then he never says how much precious metals are worth at the end??? What your doing is ace but I'd like to know how much money you've made, that's the whole point of what your doing?l.🛡️🧐
