Hi! Only the pins have gold, no bondwires in this tipe of cpu.

All the filters from silver and gold recovery/refining.

What I don't understand is how there is still gold and silver in the filter papers and as supposed you rinse the filter paper with water very well after finishing filtering the aquaregia or nitric solution bearing silver?

@@ayhamhafez285 i can't rinse 100% the dissolved metals from filters not metter how hard I try, always left some. The dissolved sterling silver and other old silver items always carry some gold that i catch in the filters as black/brown mud. When i filter gold solutions and have silver contamination the filters catch the silver chloride. Lot of ways can have left precious metals in the filters thats why everybody save them.

Hmmm, I think I lost a lot of gold since I didn't save my filter papers at all, usually I use cotton filter so it take a large space comparing to filter paper. Just to make sure that I understand you well, gold that you got from the scrap filter paper was contaminated with silver chloride, right?

@@ayhamhafez285 no. The filter papers incenerated and the silver chloride turned to silver oxide, silver/ or oxide both is soluble in nitric acid, the recovered gold is pritty pure 98-99% the remaining contaminations are possible platinum group metals.

I have time, and 2 buck worth of gas not much to me. 🤷‍♂️ and first of all this is a hobby of mine.

There is no bonding wires in this type of cpu. It has a surface mounted silica chip that not connect with bond wires

🤣🤣🤣🤣🤣🤣

Maybe 0.5 - 0.7 g.

In mixed ram cards

Scrap yards or ebay.

@@ogbullion Big fish have taken over this sector here, it is very difficult and expensive to find it.

Same happend here .

Yes.

Yes urea works as well. Denoxing is removing the excess nitric acid from the solution.

Yes its different in purity, not .999 fines.

@@ogbullion does it also affect the amount of gold extracted?

@@sp7z138 if i melt the foils i got slightly more wight but that weight is the inpureities (copper or other junk metals)

@@ogbullion thanks a lot for replying

@@sp7z138 no problem! Thanx for watching!👍

These are ceramic CPUs, not soluble in sulphuric acid.

@@ogbullion I know. But then there is also no hazard of losing bond wires suspended in the goopy mess the sulphuric acid/plastic leaves behind. And also those ceramic processors don't have any gold bond wires in them that could get lost.

I lost a lot of gold in the fiber glass mass i made. Ashing and grinding and panning with gold pan probably a better option.

Half a gramm/pound is normal for this tipe of IC chips.

@@ogbullion I have to believe you. I'm still collecting stuff... But other videos show significant higher yield. Usually twice.

22 Karats.

Nope I cant put 50 more protons to the copper to turn into gold 😆🤣 but those not aluminium bond wires anyways??🤔 Thanks for stopping by OwlTech you are a legend! 👍

@@ogbullion the reason I asked is that I had almost 10kg BGAs with copper bonding wires and was very surprised by the extremely low yield

I remember that video its insane. My first tought that someone separated the valuable BGAs from the non valuable ones(I don't know how) and sold the copper ones. I dont know for sure. But im sure it's not your fault beacuse you have a pritty big knowledg of precious metal recovery from any kind of e-waste.

I'm not gonna argue with you.Think what you want. 🤷‍♂️
