Hello my friend ! All your gold is in your vitrified slag... I had the same problem a couple of time at the beginning when i did this method instead of "all chemical process". Try this if you mind : On a furnace ( Temperature must be higher than 1200° ). Prepare 1 unit of slag and add twice time soda + 1% sodium hydroxide flex + 1% borax. Start heating till all your mix is red and bubbling. Then add lead and silver ( 80/20). ( Too much lead will not help you.) Time depends on your furnace and weight of alloy but do not get rid of slag ! When pouring the mix, use the tallest mold you have to keep density deposit. ( Let cool down alone.) Your slag must be cleaned... Repeat till all material is proceeded... Do your cupellation with portland cement. Polymer are a shit in pyro-chemical process... Hope this will help you. Regards.
I have found that BGA chips that come from television boards generally do not have gold in them, they are usually made in China, and the bond wires are made from cheaper metals such as aluminum. If all the BGA's came from Computer motherboards, your yield would increase greatly.
I absolutely love seeing you work over the years and your different methods of recovery etc. the cupellation didn’t make sense years back to me, but seeing it for these larger scale recoveries now makes total sense. I did have a question: Would you be willing to make a video of you taking all your slag, breaking it up into fine particles, and then separating the heavies from the rest and recovering the minor lost metals ? I’d love to see that!
Interesting, I'm so glad I'm just the woman who tears down the e-waste collecting all the components and others are the ones who refine it, it looks complicated! Trial and error though, all is not lost, you've shown others what can happen and the comments section has given lots of awesome tips 👍
Plastic top BGA's are the best for gold but you get 3 to 5 grams per KG on average, Copper tops are newer made with many metals Copper or alloy bond wires
Realmente foi perdido bastante ouro ai nesse processo 😢 o método de remover a silica com acido sulfúrico iria te trazer mais retorno parabéns pelo vídeo 👏🏾👏🏾👏🏾
In my experience Cu topped BGA's yield about 4.4g of Au per Kg Cu BGA tops (bottoms removed), so I would have expected about ~20g of gold. Always enjoy your videos. :)
The only explanation that came to my mind that the mixture wasn't thin enough due to the high silica content there which worked as an acidic Flux so you needed more basic thinners such as soda ash Check the slag, something is wrong of course, more than 75% of your gold is missed
With BGA´s it´s always a risky operation. If they aren´t some old branded Intel etc. you cannot predict anything. Gold corner also do not assure the yield. From my point of view, incinerated chips passed through the sieve could be very easily washed with water to remove most of the silica fillers and remaining carbon and silicon. The rest is incinerated again to assure no carbon left. And leached with AR. Altough I see you have an established route for processing scrap with pyrometallurgy. Keep doing the good work. And try to smash-grind the piece of slag and pan the powder to see if some gold isn´t lost in it. It doesn´t look very thin, and after incineration, material didn´t look grey, but black. Maybe some carbon in the slag trapped the gold.
Once you incinerate the chips and remove the copper heat spreaders, you only need to rinse with water several times till most of the black plastic is gone. Some people grind the chips in homemade machines like trinity gold recovery link Isent you not to long ago or they use anything to crush up the thicker pieces of plastic, hammer, coffee can with call bearing etc. Where you're done washing you have a big ball of gold bond wires, silicon chips and and a little bit of other junk.
The slag was very thick and also frothing a lot, perhaps the gold was trapped there. I feel like it should have been heated until the frothing stopped to give small particles time to settle. Perhaps a different flux composition for greater liquidity too? Your videos are great!
You should get around 1% from 3.4 kilograms, so like 35 grams. I have done 2 kg mixed bga, after removing the botoms and coolers i got only 640 grams tops, boiled in 95% Sulfuric acid, washing with tap water, after clearing, washing with distiled water then ad 50% Nitric/50% distiled watet, after reacțion done, wash, then AR,, denox, precipitate. Your gold shold be stuck or in cupiled lead/silver, or in disolved glass.To disolve the glass you need HF, Hidroflouric acid.
TH-cam is full of videos of processes with extremely high yielding material, and - I suspect - videos with added gold to make the result look more spectacular and making a bigger headline. BGA chips are hit and miss. You never know.
Hmm sneaky move if those werent sold as heat sink bga's. A mixed lot should be way less copper plates. Or at least i would have to set them aside from others to get that many. When depopulating boards i find alot more of the other type. And as you found out. It's pretty much the majority the weight, Skewing bga estimates. But I also wonder what the slags rechecking will produce. As suggested in the comments.
bonjour, n'oubliez pas qu'il a des composants électronique de contre façon ou faux et ne mette pas or ou un peut par rapport aux originaux. Bonne chance pour la suite
Great video. Remember new chips have lower gold. I would re process the slag, maybe have a cone mould to gravity separate in cooling, like mbmmllc. Also some borax to thin the slag and allow more metal to sink down.
And an iron rod? AGrre borax and cone mold. That slag removal looks way to dependent on skill and circumstance. And I could not tell what the cupel method was. I did not see anything added like crushed sea shell powder. Was it all evaporation? And do you breath that?
*processing 1 kilo of BGA*with copper plate recovers *5 gramas* on average, in its process *9.5kls* taking into account only the silica buttons without copper plate calculation from what I saw in the video *2.2kls* of silica buttons *20.2* grams of gold details processing in sulfuric because incinerated and deep there are many losses in the process like my good friend share what I learn
wrong incinerated > lost gold. You still had black coal, it's adsorbent for the gold. And lead smelting is not a good method for non ceramic cpu/chips etc. This material have 10 gr in 1 kg around without copper discs, with them around 8 gr per 1 kg
Добрый! Давно и с интересом наблюдаю за Вашим творчеством. По поводу BGA два соображения: На видео black tops видно мельком но из того что видно складывается впечатление, что многие black tops имеют heat sink(металлический колпачек для отвода тепла), а это дополнительный вес. Обычно считают выход по Intel, возможно в Вашей смеси содержание ниже.
Мыслите в верном направлении. Если верить видео из ютуба и тематическим форумам, то шапки с радиатором содержать 4-5 г золота на 1 кг шапок. Шапки без радиатора 8-10 г/кг. Даже по самым скромным прикидкам (все шапки с радиаторами и содержанием 4г/кг), то получаем 6*4=24 г Au. То есть даже так взяли чуть более 50% от ожидаемого. А так как были шапки и без радиаторов, то потери гораздо больше. Причина в методике извлечения. Я думаю, не нужно было добавлять серебро. Серебро добавляют при квартовании, а это отдельный процесс. А там кто знает...
If you had all copper topped BGAs this will cut down on the yield because you sawll how much they weigh, this cuts done on bgas per pound compared to someone doing bgas with no copper pieces.
The pyramid shaped cone is the way to go for sure. No messing around, melt your lot, pour it in, let it cool. Just remember that your salg may still have some recoverable material, save it up and run it again at some later date
That is because of weight of heat sinks on top of epoxy and because that BGA gold corn.chips are made after 2005 yr. Collect only made before 2005 yr. after that year is gold plated copper vires. All the best witches for you from Serbia. You have my SUB and LIKE.
BGA's ain't the only things with gold in or on them. IC chips, cpu's, rams have gold fingers, many comptuer cards, cable pins, are gold plated. and scan boards on flat screen tv screens have gold plated fingers on them.
@@OwlTech333 ah maybe from the same board. All having copper. That's ashame then. I've had chips wreck my yield a lot. Since then if I have hundreds of the same board I take of 50 or so grams and burn put in water and you should see gold wires sat at bottom.
You have nitric acid should go straight to that to remove base metals and silver then aqua regis for gold and platinum no need that add lead and silver.
i think u got the wrong bga those ones got tin copper tops they low grade bga the one that have the 10grams on top and 3 grams of gold for the bottom part on the are the full black top ones with no tin copper on top and not those ones cheers
Yes BGA’s are funny buggers. Did a load in sulphuric boil, and was not impressed with result. I always separate the metal cap ones as well more modern ones are overrated.
You only really had 2.9KG of material, and to get 12 grams is not too bad. You have to take in consideration that weight of the heat sinks is not workable material. Thanks for showing us to avoid them heat sink toped BGA's, you're better off selling them.
@@OwlTech333 that's a lot of weight to lose my friend. When I have seen yield results for gold corner bga chips it has always been without copper tops and no fibre bases. The result you have is basically the a 2.6kg recovery. It's sad that people mess with buyers like that
@@OwlTech333 in my experience I have never had gold corner bga chips yield this badly. Something I will say though is there has been a rise in fake components supplied for ewaste. I've seen CPUs and some other chips that have nothing Inside them
Where do you go about getting this amount of e waste? Been looking ages for a reliable source for CPU’s but Im not sure if the people messaging me are scammers or not
there's no such thing as a reliable source, and yes most of the times people selling e-waste are either scammers or they sell it for a price which leaves you no room for profit
hello dear i saw some gold recovery from trinity gold recovery channel! i think u wasting gold in ash melting process your methode not good using acid instead of melding with lead!
@@scrappydoo7887 I agree with you It may have been realized as a result (u know what i mean :) But working with acid and attention to detail can affect the result Of course, the type of material is important. For example, the type of RAM that is produced by different companies and the amount of valuable materials in it is different!
@@saeeddamangir1159 100% you are spot on 👍 There's wildly variable results on RAM. I agree that using lead is unsuitable for chips, I did the same on a smaller scale and the results were poor.
BGAs will always vary, the bigger the chips the lower the yield, especially copper top BGAs. Ive seen crazy yields with smaller BGAs they use as memory but on GPUs or on other boards that aren't memory. No set yield with these unfortunately
I'm just voicing my opinion here but it looks like you needed to incinerate and grind the resulting bgas better. I always grind to a powder fine enough to pass through a flour sifter.
@@OwlTech333 it's funny because I have watched several of your videos and feel like I learn new approaches to things by watching you, I never would have thought I might have something to say that might help you
@@OwlTech333Ou sh..t ..at list we saw a good video with smelting technic ... And a very good lesson for all small or big scale refiners to don't expect the top gold ...
You probably got the rest of your gold in the rest of that material you separated it out That's I processed electronic scrap before and if you don't pay attention to the stuff you think you're separating out you end up losing so that's probably where it went and it's just too much work you mess with it only thing I ever refined now is carrot gold jewelry scrap
I dont know why all your videos have smelting. Since you ended up doing a nitric bath anyway, you could have just put the ashes into nitric like its meant to be done. And then aqua regia. You didn't need to waste time with all the smelting process
You haven't seen All my videos judging from your comment. I'm using far less nitric acid to dissolve gold alloyed with silver than dissolving copper wires.
При всех расходникам , я не поверю в потери в 30 с огромным хвостиком грамм на 9 кило материала ! Даже если бы я лично не пропускал этот материал через руки , то голову бы все равно включил , такие мосты за кило давали скупки по цене 1.5 грамма голды по бирже ! Если бы в них не было того веса о котором сказал , а показанно то что на видео , не один здравомыслящий себе в убыток работать не будет !!! Куда " испарился " большооой хвост рыжика , большой вопрос !!!
Congrats on the content. I believe it must have gold in its vitrified slag. In the convection movement, some concentrated points may have been pushed up, remaining in the vitrified slag.
В чипах с радиаторами никогда не было 9 грамм на 1 кг и рассчитывать на вес в 90 с копейками это обсурд . А вот 5-6 гр на 1 кило это реально . Видео монтированно , и что где и куда не известно ушло . Обвинять не в чем не буду . Но уловок много , где оно может " улетучится " . Так как и при осаждении , залил осадитель , что выпало в первые минуты показал а отстойник который полон есчё не осажденной взвеси испарился . Здесь все возможно ! Это Ютуб ! Но кто то кого то очень хорошо нае.ал !!!
Why did you expect a 60g yield? BGAs contain 4-5g of gold / kg. After you removed the copper heatsinks, you had 2.9kg of BGA ashes, so 2.9 x 5g = 14.5g of gold is your maximum yield. You've got 12.8g which is ok, I think.
A very good video of how not to do it 😢 You should avoid the ones with the huge round heat sinks they are very bad mainly copper weight very little gold.
Thanks it wasn't my choice which ones to pick, and even if it was I still would have picked the wrong ones probably! This entirely new type of scrap to me 😁

Yes that is true I had 140 gram bga top part or led tv or LCD tv but I got 450 mg of gold it's so bad result.

Yes BGA’s are funny buggers. Did a load in sulphuric boil, and was not impressed with result. I always separate the metal cap ones as well more modern ones are overrated.
Copper topped chips will always yield WAY LESS because of the weight, we could see another 2000 plus grams of copper alone in his
the smelt was no good you lost a lot in the slag , next time ad the lead when every thing is melted and keep it melted for a cople minutes stiring it
why i feel like you've lost some gold in the early processing 🤔
Maybe because you’re right
I find your videos very interesting, thanks for uploading 👍
Thanks
The gold is present in the slag of casting and slag, re-cast both of the slag again, and re-slag it, you will find the lost
And another note, you did not burn well or grind well, and this is the most important cause of loss, and the correct ratio is from 40 to 50 grams.
That extra gold is there somewhere.
I'd be boiling everything in acids to recover it
10 grams per kilo was never gonna happen
Omg these bga must be crap there putting copper/aluminium bond wires in instead of gold surely 😟
That’s what I’m thinking
If the seller has an xrf gun...toss the low yield in the resell pile...repeat. like the guys that sell a bag of magnetic mlcc ...
Your BGA can be sold for 1363 euros. How much is your gold worth?
Not much
I imagine you scraped away a decent amount on your “cupellation” it’d probably be better to use Portland cement or a bone ash crucible
If there is a problem with the process it’s in the smelting, rather than the cupellation
Total bummer. Did u ever figure out what happened? Either way interesting.
Not yet but I'm inclined to tink that most of the BGAs had copper bonding wires

Since you ended up doing a nitric bath anyway, you could have just put the ashes into nitric like its meant to be done. And then aqua regia.
You didn't need to waste time with all the smelting process
You haven't seen All my videos judging from your comment. I'm using far less nitric acid to dissolve gold alloyed with silver than dissolving copper wires.
@@OwlTech333 oh ok. Nice
Отличная работа, брат!
Muito bom meu amigo parabéns 👏🏾👏🏾👍🏾
The best way to get gold from this stuff is using sulfuric acid not burning
Thank you
You're welcome
And what about 200g silver?
The silver was recovered and refined
You might want to check your Crucible or your melting dish
При всех расходникам , я не поверю в потери в 30 с огромным хвостиком грамм на 9 кило материала ! Даже если бы я лично не пропускал этот материал через руки , то голову бы все равно включил , такие мосты за кило давали скупки по цене 1.5 грамма голды по бирже ! Если бы в них не было того веса о котором сказал , а показанно то что на видео , не один здравомыслящий себе в убыток работать не будет !!! Куда " испарился " большооой хвост рыжика , большой вопрос !!!
I've done so much, it's impossible, check out the ruins, we love you, we're looking forward to your videos
Are you using charcoal
Coke
Congrats on the content. I believe it must have gold in its vitrified slag. In the convection movement, some concentrated points may have been pushed up, remaining in the vitrified slag.
What type of alloy sheet metal are you cupelling on?
Stainless steel
alwaya look for intel bga for gold recovery
Das sieht mehr nach Spielerei aus, als nach Goldrückgewinnung.
Респект 🔥🔨😎👍 отлично снимаешь 💥📽️☀️📸🚩🌐👻
Why is smelting the only method you know ?.
You could have just treated the ashes in acids and you would have recovered lots of gold
How can you recover something if it was not there on the first place
Only?
добрый вечер Ув. Сова😊
Надо было золу сразу в царской, даже из самые бедные мосты должно получиться не менее 25-30гр с такой количество.
Excelente.
The ones with the cap contains 0 gold
Wait!.....have you stripped your country clean of all the high grade stuff?🤪
В чипах с радиаторами никогда не было 9 грамм на 1 кг и рассчитывать на вес в 90 с копейками это обсурд . А вот 5-6 гр на 1 кило это реально . Видео монтированно , и что где и куда не известно ушло . Обвинять не в чем не буду . Но уловок много , где оно может " улетучится " . Так как и при осаждении , залил осадитель , что выпало в первые минуты показал а отстойник который полон есчё не осажденной взвеси испарился . Здесь все возможно ! Это Ютуб ! Но кто то кого то очень хорошо нае.ал !!!
good job
intel and sis brands are the best
I totally agree!
Good
Thanks
Why did you expect a 60g yield? BGAs contain 4-5g of gold / kg. After you removed the copper heatsinks, you had 2.9kg of BGA ashes, so 2.9 x 5g = 14.5g of gold is your maximum yield. You've got 12.8g which is ok, I think.
I was expecting 95g, but then I saw that 10-12g per kg is for black tops only
Bonjour
comme toujours 💗
merci beaucoup pour votre soutien continu tout au long des années
It is very interesting, it should not come out so little, I think you have lost as a result of your wrong transaction.
A very good video of how not to do it 😢
You should avoid the ones with the huge round heat sinks they are very bad mainly copper weight very little gold.
Thanks it wasn't my choice which ones to pick, and even if it was I still would have picked the wrong ones probably! This entirely new type of scrap to me 😁
@@OwlTech333 New to you?! I would have thought you’ve seen and done it all.
@@fuhk haha far far away from it, you'll be surprised how little I know
@@OwlTech333 surprised I am.
