In this video I will show how much gold can be extracted from one telecommunications board. I hope my video will be useful to someone. If possible, if you liked the video, please support the video with a simple like. Thank you 🙂🖐
Great video as always AK! Pulling the gold from computer and boards scrap is always the best because we all know how many just end up in the landfill... I also watch Mike the Scavenger because he rescues the metal scrap and gets paid for it. And I watch Bigstackd because he shows what else can be done with nonferrous metals 😊. You all are great! Thank you so much for creating enjoyable and fascinating content! You and sreetips are my favorite refiners to watch because you drop so much understandable knowledge and your videos are always true, meaning if you make a mistake you film it. Have a wonderful day, and again thank you!
Thanks for the kind words. I also watching Mike the Scavenger. Four years ago, I also jumped into dumpsters to get old electronics out of them. But one day I met an old grandmother who was shocked that I pulled a broken flat-screen TV out of her dumpster 😲 She even called the police 😅 The police laughed with me and politely asked me don't touch her trash in her dumpster. After that I decided not to jump into dumpster anymore. Sometimes people react inappropriately 😉
Bear, I love your work as uoy know so forgive me if I make a suggestion...... I agree with boiling down but then re-acidify with HCL and refine a second time. Add a few ml of H2SO4. Filter and if you are after really pure (99.99+%) do it all again. With each precipitation with a different precipitant. (Oxalic Acid, SMB, Ferrous Sulphate). I have achieved 99.999% this way many times. Sure My washes of the gold powder between refinings is mush more rigourous than yours ( 5 X H2O, 5 X HCl, 3 X H2) H2O, 2 X ammonia, 5 X H2!!!) Godd luck and keep the great vids.coming. Oh One other quick thing..... the first filtration after rehydration with HCL should, in my opinion be through a medium to slow filter paper not cotton.
Sorry, but I don't agree with you. If, after evaporation, I dissolve gold salts in water and add a little hydrochloric acid, then I will automatically convert a small amount of solid chlorides of some metals (not all but some of them) back into a liquid state, and after filtration they will go into a pure solution with gold. No no no! I do not want it 😬
About filtration funnel and filter paper, I have everything, but I noticed that filtration through a funnel with cotton or funnel with a piece of towel is much better and cleaner. It just doesn't looks professional to the eyes of those who watching video. But I don’t care about this. The main thing is that after filtration the solution is clean. 👌🙂
Bear if you follow your logic through you, what you are saying is that there are still some metals in the sslts after evaporation so converting them to chlorides and then filtering with a medium to fine filter paper will remove these chlorides is positive!. Cotton will not remove all. I am not critical of cotton, I use it as an early and easy seperation method but a good qualitative filter paper in immesurably more effective.
As a check, use your method then re dissolve the gold in AR and use my suggested method (add wate + HCL and filter with fine paper) and then look at the paper under a microscope (if you have one?) you will immediately see chlorides.
Always happy to discuss further.....😇@@akgoldbear7669
"Always happy to discuss further" ... me too 🙂
@@akgoldbear7669 My husband also has professional filter paper, but he uses regular cotton wool
You explain everything very well. I like that you're not lying about the purity of the gold. Thank you for the video.
My pleasure! Thank you for supporting my video with a comment )
Great video! Thanks for your hard work
Glad you liked it 🙂🖐
Waste pot solution looks like iron. Siphon the blue liquid off, add hcl and see if it dissapears.
I drained all this sediment on the coffee filter, when the sediment will completely dry, I will think about what to do next 🙂
Today I found out that there is palladium in my waste bucket. That's why the color of the gold sediments was different.
Happy new year to you too
🙂🖐
As usual, very very interesting!👍
Thanks for your continued comments, I appreciate it 🙂🖐
The gold from old board is mix from gold and paladium ❤❤
You are 100% right! Today I found out that there is palladium in my waste bucket. I've already extracted it 🙂
@@akgoldbear7669I think the white colored connectors after removing the pins are also palladium plating
I extracted almost a gram and a half of palladium from the waste bucket and to be honest I don't know which pins had palladium. I drained the dissolved base metals into one bucket 🤔 I think palladium was on the new pins 🙂
Hello AK. I Love your informative and cool Channel. What tells you,, the moment,, you have put enough Iron sulfate for the precipitation? Thank you.
When adding iron sulfate, if you see small gold flakes on the surface of the solution, it means enough 😉
@@akgoldbear7669 , perfect, thank you.
Very nice 👍🏼 happy new year AK 🎉🎄🤙🏼🤙🏼
Thanks 🙂
Nice video
Thanks ✌
Happy New year to u from the UK
Same to you! 🙂🖐
Good job as always bro, great to you😊
Thank you! Cheers 🙂🍺🍺
Wow nice board
I thought so too 🙂 And it turned out that there was not only gold, but also palladium. Today I extracted 1.5 grams of palladium from the waste bucket. That's why the color of the gold powders was different 🙂
I am confused. You started dissolving 100g of old pins, and weighed 3.9g gold at the end. Did you do the other 300g of old pins off camera and added the gold together for 3.9g (you said 3.9g for the board, which yielded 400g of pins), or do you still have the 300g of pins left? It would make a drastic difference to the gold yield!!
3.9 grams of gold from 400 grams of gold plated pins. I dissolved 100 grams, then added another hundred grams and so on. This way dissolution going much faster.
This video might help me out to decide to finish taking pins from my computer boards.🙂
It is easy to dissolve and then extract gold. But prepare material by scrapping electronics, personally for me is difficult. I have to spend a lot of time. I finish work at five in the evening and then i spending another five hours scrapping electronics... Thank you for spending some time on my video 🙂
@@akgoldbear7669 I have alot of computer boards but is it worth the time for the small amount of gold. Seems as if the pins have more tin than gold. I know I did those pins wrong by not putting them in hcl first. I had alot of white powder substance with that batch. But the mid grade pins not sure what I did wrong. Hopefully I will recover something as I save the aqua regia after using smb.
Nice, I've been using eco gold x because I just got about 30 lbs of unused gold plated interconnect pins. Very long pins, 25 mm of gold plating. To do that with Ar would take to much fluid. So I did some testing. It seems 166 grams of pins produces about .2 grams of Au. How do I know with eco gold x? I weighed the pins first, stripped the Au from them. Then I Washed, dried and reweighed the pins. I did that 4 times, the result was the same every time, .2 difference in weight. I mixed 400 ml of eco gold x and recovered 3+ grams, but like a dummy I never paid attention to how many pins I did. The math says I did over 5 lbs with 400 ml of fluid. So I made another 400 ml. Pins remaining weighed 22 lbs. This time I pushed the solution hard and cleaned 10 lbs of pins before it could take no more gold. Now it's so cold I put the solution in storage. I have 12 lbs of pins left to run If I mix up 500ml I should be able to finish them. In the mean time I'm removing IC chips, lots of them. All the material is dated from the mid 1970s' to 1990. My guess , I have well over 1000 lbs. Lots of work to do.
Hello. Jesus Christ! You have a lot of material! I don't use Eco-Goldex. Two years ago my friend gave me eco-goldex to try remove gold plating from thin processor pins. He explained to me how to use the solution correctly, plus I watched a lot of videos on UA-cam on how to use eco-goldex correctly. The gold dissolved quickly, I got three grams of gold and I was happy. But after a couple of days I decided to dissolve the pins in acid to get copper sulfate and when I dissolved the pins, I decided to test the solution with tin chloride for gold content, and it turned out that there was gold in the solution. I extracted another half gram of gold from the solution. After this I decided not to use eco goldex anymore. Maybe I used eco-goldex incorrectly?! I don't know.
@@akgoldbear7669 Well it takes at least 2 recovery steps to get all the gold out. I did a 3rd recovery on the eco but nothing came out, so just to be sure I dumped the solution into my stock pot. I've been doing this for about 10 years. I work with a salvage company, I'm not an employee. I get everything for free, they pay for all my chemicals, equipment, everything. Then we split the recovery. It was quite the surprise years ago when the owner told me he had a NASA salvage contract. That stuff has crazy , insane gold content. 5 years ago we got a load fo stuff from the space shuttles. I'm still running some of it. I like doing it, theres a challange with all of it.
@@akgoldbear7669 Oh the board you did in this video. I can't count how many I have to run. 100, 200 I have no idea. I do know this, if you heat the pins with a hot gun and tap them with a mallet they will fall right out. There not soldered in, just pressed in. The heat softens the board and they come right out.
After boiling down you MUST re-cidify with HCL otherwise the reaction with SMB will not work properly.
Thank you. I did not know. 🙂 But still, I think it will work, since I have done this many times before. You saw, as soon as I added boiling water, the reaction began. I didn't add Hydrochloric acid, right?! The gold solution was just ice cold 🥶
agreed but, did you get all the gold?@@akgoldbear7669
I definitely got 99% of gold. I think yes. I'll catch the rest of the gold in a month from the bottom of my waste bucket.
❤
Thank you for visiting my little channel 🖐
Cok guzel bir video olmus.kral suyundan coktukten sonra.coken madeni lehimi almak icin hidroklorik asitemi atiyoruz.saf altini almak icin.genelge mavi toz çok oluyor.bu bakır sulfatmidir.
Awesome. Thanks for watching and commenting :)
Your in ga right? Would be cool to talk all this stuff one day I got a few boxes of parts to play with.
Yes, i live in the state of GA. I don't take old electronics anymore. I have a big storage and it's full of all sorts of electronic junk, and i don't have time to take it all apart.
Not a good plan using aqua regia first. Should just use nitric first
Hello 🖐 Nitric acid first, why? For what purpose? 🙂
سلام استاد این تخته پین وزنش چند گرمه وایا مخابراتیند متشکرم
Здравствуйте. Понятия не имею сколько весит вся доска. Вес всех золотых штырьков составил 400 граммов. 🙂
The rest of the gold s in your wast pot I bet...
Yes, there should be some gold in the waste bucked. I'll take it out in a month. 🙂✌
I like how you quickly find solutions when a problem arises 👍
Experience comes with years. Thanks for watching and commenting 🙂 Thanks for your support 🖐
That sediment, silver? The actual pins, minus gold plating ??
No, not silver. Pins that are half gold plated are not silver, they are tin plated.
Sediment That looks like a Hydroxide .
Thank you. I drained all this sediment on the coffee filter, when the sediment will completely dry, I will think about what to do next 🙂
@@akgoldbear7669 Incineration
👍👍❤
