You can see the difference in you from the beginning, back in 2015 to this video. You've researched and educated yourself about most of the components of the circuit board. At the beginning you were taking all the IC chips and now you have 5 categories or more for just IC chips. Plus so much more! Thank you for the research you've done for yourself and us.

Great videos! For impatient guys like me, listen to this on 1.75X speed. Ben can still be clearly understood.

Thanks Ben - another good discussion. At this stage, I'm kind of aligned with you. I remove the CPU, Al Heat Sinks, and some of the BGA's, IC's and flat packs. But this is because of how my yard grades boards: high, medium and low. A partially depopulated mother board is still high grade. So I pull what is quick and easy and move on. I usually take the bigger MLCC's and Tantalums as well. And of course the crystals - because...who knows.

Ben in 2018, palladium will be equal to gold soon! 2022.. palladium $2556 oz gold $1758 oz glad I've found this channel! Big props man, love the content.

Wish I had seen this yesterday... I mixed about 20 boards of those dang bronze pins in with my other little bits of gold pins...

After total depopulation, followed by stripping the resin with hot lye, copper recovery from the boards is easiest by using copper sulfate reverse-electrolysis. You can set up quite a few boards in a big old fish tank or plastic tub and run them all at once.

How/where do you acquire so many boards? Right now I only get them from the side of the road. Do you have a deal worked out with local shops?

What to do with your base metal waste solns: precipitate with carbonate! Most transition metals will just fall right out of solution as carbonates! Then, roast them at high heat and they'll decompose into oxides (some may totally reduce to metal if the heat is very high). At that point, you have enriched transition metal oxide, which is basically high-grade ore some refiners will buy if you have a pile of it. They'll test it with an XRF spectrometer to determine the composition and value.

Tin and bismuth are the main problem metals. They form insoluble goop in nitric acid. Always clean components off with HCl first. For brass-containing parts (which have tin in the alloy), use HCl with 3% hydrogen peroxide and aerate for at least a full day to totally dissolve the base metals. The tin and bismuth should remain in solution by this method, then you can filter and refine the solids with all the precious metals.

Nice Video..... Nice work ...! Great .. !

It is more fun to try it mate.

Thumbs up Ben..Be extra aware of the relay's and switches.

Ben, folks keep fixating on the color of the motherboards. The color of the solder mask is just a choice. The greatest metal weight in the board is copper whether the board is green, blue, tan, and so forth. For cleaned off motherboards I can get $1.85/pound or $2.55/pound for a populated one (they want CPU and at least minimum memory). For me at least it would be beneficial to clean off motherboards as I only do this to burn time when I am board. On the PCI slots, I always thought these were nickel plated with gold. The tiny amount of phosphorus wouldn't make for high quality electrical throughput. I would never take yield ratios seriously as they are horrible at best. I have only seen one attempt that had face validity. This guy hand several chip models with nice quantities of each. He took a known quantity of each model and processed them together. He then calculated his expected result for the remaining volume.

Hey Ben when you sale the boards will they separate high,mid and low grade boards? Or do you have to before you get there?

👏👏👏

You've said things that needs to be said. I am saddened when I see people just going for the gold and trashing everything else. Before I get serious I will have a destination for everything removed. Hopefully I will get to recover the copper embedded in the board. I still have every board I've depopulated.

Hey Ben! Great video as always. Would it be worth taking some items off the board like the bga chips or high yield mmlcs and than sell it as a mid grade board?

Hi Ben, when you described laptop motherboard, there is a lot of 8-legs chips which looks like IC Chip. Is it IC or is it something different, not worthy to keep? Honestly I am keeping them, because I keep everything which I am not sure about. I am also not refining anything yet, just collecting like little hoarder :) (I don't have space to keep boards, so I take what I want and then I sell the rest to scrap yard, they pay fair even for depopulated boards)

hi bro,can i buy depopulated computer boards from you?

I scrapped a few laptops and didn't know I should take them apart

Platinum used to be the most valuable overall.

U well right palldium alot better price now over paltium

great👍

Hey Ben do you no how I will find a scrap yard that takes waste I'm in Sydney and I like doing my scrap

Spoiler... He doesn't depopulate anything in this video, but spends 45 minutes telling you to sell your e-waste.

no one buys circuit board in my area, i have to depopulate almost every component for secondary market sale

Hey man, I noticed that you posted to /r/silverbugs a little while ago. Have you ever gone to /r/preciousmetalrefining? There is a lot of good info there even though it is a slow and subreddit. anyway, i love your informative videos. Keep up the great work.

Boa noite ..eu gostaria de saber se embaixo da tinta das placas do CPU tem banho de ouro?

No one will buy boards in Sweden privately for scrap. Some scrapyards pay average price of about 20cents (US) per kg for ANY type of board, even telecom boards. So I have depopulate everything or loose everything. Least they buy the stripped boards at 20cents a kg.

We get our best money for scrapping mother boards here in the U.S.A.

Hey Ben, I'm starting a small electronic scrapping business. Do you have any tips for me?

Over 90 metals on the periodic table and yet so many scrappers focus solely on gold recovery.

copper lid in bga chip still constins bonding wires. But the copper is heavier than plastic and reduce the value per kilo. and often the copper is magnetic in bga chip

furnace ????

Boa tarde .. gostaria tanto de entender o que vc fala ..pois aqui no Brasil seus vídeos são importantes pra mim

Very interesting thinking maybe just depopulate the whole old broads and keep everything I don't get nothing for the broads here Trying to learn how to get all metals not just gold and silver before I refined even saving the silicon chips people are making art or jewelry out of the wafer Thanks

Is anyone looking for 1990s cd rom

The ebay is fucking expensive. I never buy e waste on ebay.

Waaaaay too much talking about the same things. No need to over-talk subjects to death

17mins worth of useless ranting about the metals backyard refiners CAN'T recycle anyways is stupid. If you're going to rant like that, make it a seperate video ffs.

Just do it. Stop talking
