Great video and amazing timing. After my post (the one you quoted here) I decided to take another look at my tantalum waste and see what I could get from it. I soaked what I had left from my last batch (filter, ash and all) in 50/50 sulphuric acid and 35% H2O2 mix and it cleaned up quite well. After a really good washing I am left with a dark, heavy residue with small tantalum slugs in it. I assume these are the ones I didn't crush after burning them. I checked online and tantalum is about 16. times denser than water and since gold is about 19 times denser than water I'm thinking I could use a mini sluice to further concentrate it. just like if I was mining for gold. I would have to mess around with water flow rate and sluice bed angle but I think it's doable. It's gotten quite cold here now so there is no way I'm doing this until spring but over the winter I'm going to see if I can build some sort of table-top sluice and try to separate the tantalum powder from the rest of the waste. From what I can see, other than the tantalum, most of what is left appears to be mostly ceramic dust, silicon dioxide and inorganic trash. which SHOULD wash away leaving the tantalum behind Most of it appears to be much less dense than the rest so I am hopeful for good separation. If this works out I think I should have much better luck finding a buyer for the tantalum powder even if it is at most 80% pure. I knew you'd get a good amount of silver from these things and well worth processing even if all you want is just the silver.
I would have never thought there would be so much silver in those. I'll have to start plucking them off now. I have found no one to buy tantalum so I had left them on the boards in the past. What a mistake..... Thanks for sharing your results
Dusan, thank you so very much my friend. Your information is absolutely priceless. My family &I wish you and your family the Most Blessed of holidays and good health.
And There goes the best keept secret of tantalum buyers. silver is a super bonus for them your curiosity is dangerous man. Thank for that data and keep videos comming...
brilliant video..I love all your experiments.you keep me well informed.im just starting out and leading my trade and your videos are very very helpful.anyone from Ireland want to drop me a line for a chat
From my personal experience the black ones have a higher silver content. I've run batches of both and the yellow seem to run around 6% by weight and the black closer to 10% assuming VERY good washing is done. Takes a LOT of water to really clean up the residue though as the ash seems to hold onto a lot. Now I don't bother separating them at all. They all go into the same bucket at this point.
@@keytefirerefining1355 That's what I am thinking now too. After revisiting this and getting rid of all organics with the H2SO4/H2O2 I am 99% sure I can further concentrate with a water sluice and get with of the remaining ash and ceramic dust. If it does as I hope then it will absolutely be worth my time and effort. At least now I have a process in mind that changes them from waste to potential revenue. That's the part of this hobby I find most enjoyable: seeing a problem and using logic to work out a solution. As Matt Damon said in The Martian "I'm going to have to science the S**t out of this". lol This is the same thought process I used to begin to recover as much nitrate salts from my silver recovery so I can use them to make more nitric acid and start the cycle all over again. I'm even working on a rig that will capture most (if not all) NO2 gasses and make more dilute nitric acid. So far I've found it easiest to do so by reacting the gasses in dilute KOH and crystallise out more KNO3. But I'm experimenting with using Ammonium Hydroxide too. Ideally though I'd like straight, pure nitric to go right back into the first step. I'm confident I will get there soon.
@@Enjoymentboy i know if you tap them with hammer the anode stays fine and the rest breaks away but its time consuming. I wonder if its possible to burn them and put in a bottle and seal then shake. Hopefully you will be left with anodes and crumble. Then just drill holes in wood the side for anodes to not fit and put it on, then you would have the anodes on top and silver and plastic at bottom

Gold hog multi sluice is a great little recirculating system you can run inside the house in the winter with warm water.
OUTSTANDING video! Thank you very much for your "test"! Happy Holidays to you and your family! Stay healthy & safe!! Jim in Phoenix, Arizona.
Thanks for the info. Before that video a taught it worthless for silver recovery. But now i know. Thumbs up!
Never think there would be that much silver...nice job.
Oh also thank you for keeping us informed on all this material. Very very helpful to lots of ppl. 😍😎😍

Well that's on my next to try list!! Thanks again, and Happy holidays to you and your family my friend!
Great result and perfect video as usual!!! 🌟 👍
Another excellent video dusan 👍👍 thank you for the very useful information

Great information and video keep up the great content 👍
And There goes the best keept secret of tantalum buyers. silver is a super bonus for them your curiosity is dangerous man. Thank for that data and keep videos comming...
wow, amazing result
Kada se Dusane moze ocekivati na Srpskom neki video, ovo sve je super...nemam rijeci 💪💪💪
That makes the capacitors well worth stacking
Great video, very good descripțion off all proces from start till the end. I will process mines too instead of selling them.
Roughly US$30 worth of silver. Not bad.
Awesome video....... 🌟 👍
valuable video
Forgot to ask - Did you test for Palladium during your 'test' run?? Thanks again!! Jim
wow nice yealdi think im gonna dig out my stash of tantys and just go for silver 👍😀👍
Its okay if we left burning and use sulfuric acid to remove plastic?
I have I kg of mixed yellow and black and red can I process together or should I separate different colored ones cheers .
Well, this was nice surprise.
Great Discovery!
WOW MAN!!
That's a sweet amount of silver!!
Have a Great Day!!!
Thumbs UP
save that ash....you have room,and time. you will get a buyer eventually!!!
Thank you Dusan for another amazing vid
Excelente.
So tantalum buyers are getting free silver with their purchase.😑
I think I will keep them rather than get $20-30/lb.👍
Hello sir your video nice
brilliant video..I love all your experiments.you keep me well informed.im just starting out and leading my trade and your videos are very very helpful.anyone from Ireland want to drop me a line for a chat
Very interesting !
Por favor como extraer tantalio? Cual video es el correcto para aprender.
Hey Dusan, can this be done with potassium nitrate instead of nitric acid?
now i consider sulpheric to remove plastic,then wash...then right into nitric. filter. then drop silver.tantalum goes another direction🤔
👍
Nice information! Are you going to test yellow ones? Would be interesting to know if they contain same amount.
will this work with the yellow tantalums also?
So do they have more than the yellow ones then?
Yellow 5%,black around 9%.
What About yellow one Do you think There is the same amount?
About to ask the same question. 😄
From my personal experience the black ones have a higher silver content. I've run batches of both and the yellow seem to run around 6% by weight and the black closer to 10% assuming VERY good washing is done. Takes a LOT of water to really clean up the residue though as the ash seems to hold onto a lot. Now I don't bother separating them at all. They all go into the same bucket at this point.
@@Enjoymentboy surely it'll be worth carefully breaking them and selling the anodes at $100 a kilo and saving the cases for the silver

Do they accept actual metals or the pieces? And can I send it to him too.?
Make video . Non cyanide gold recovery from mobile phones
dusan can you explain about sugawatter.
hi my friend. only silver? ?thanks
Gosh darn i just sold 10kilo for 115 cad. Arggggggg
Dusan,How to recover the yellow tantalum?
Same way,, half procentage of silver.

try mosfets the same process,
Thought you were saving tantalum too.
