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.

Thanks for your advice! I'll revise the slags!

Pretty sure the rest of the gold is in the Slag you spooned off when you first added the lead and silver.

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.

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.

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!

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

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 👍

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 👏🏾👏🏾👏🏾

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

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!

So good to be able to learn from you. Please take care and stay safe. 👍👍👍

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.

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.

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. :)

KZread 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.

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.

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.

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?

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.

Thank you for the good video.

Most people who get high yield from BGA chips usually wet or dry ash the chips instead of smelting.

*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

If there is aluminium in ash.gold will alloy with aliminium and have very high melting point and it will be in the slag.

good job and fantastic video? can you tel me the chemical composition of sulfamic acid, please? thank you so much.

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.

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.

The ones with heat spreader on them don't have much gold in them. Plus you need to crush into fine powder.

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

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...

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

That extra gold is there somewhere. I'd be boiling everything in acids to recover it

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.

The best way to get gold from this stuff is using sulfuric acid not burning
