Gold corner BGA chips gold recovery | Gold from IC chips | BGA IC gold recovery

In today's video I'm going to process BGA IC chips from computer motherboards , tv , and graphic cards.
With the great yield of 10 g gold per kg materials.
In first place i leached solder with nitric acid , Tin converts to Metastannic acid which i use it later to recover tin from.
Then i did wet ashing process using sulfuric acid to open ic chips packages.
after that gold bond wires became evident .
After that base metals dissolved with nitric acid (copper was dominant metal)
afterwards gold wires dissolved using aqua regia.
To expel nitric acid i used sulfamic acid then i dropped gold with ferrous sulfate (FeSO4) .
gold percipitate washed in hot HCl and melted.

We just got an order for e waste pick up from a company that needed us to dispose of 80 phones, each one has a BGA chip.

[@PickyPlans]

That's great! About 1-1.5 grams of gold. 👍

I EXTREMELY enjoy your videos. You speak slowly and methodically. Thank you and keep it up.

[@gold_extraction79]

Good

[@electronicscrapper4956]

very interesting video. I learned something today. I cant thank you enough

[@christopherdangelo3965]

Excellent break down🎉

[@copperkingrecycling634]

Awesome video. Very helpful.

Should have used more SMB

[@raymondreyes8046]

Good video, getting better and better! Very informative.

[@quintonharvey1501]

Why did you not separate bottoms from top

[@riverboat28]

Tinned copper?

[@tonytrade]

28:55 very smart!

[@julianalcorso5703]

Hey Picky, Great vid! I learned a lot especially to keep gold corner BGAs together rather than separating the tops and throwing away the bottoms. I have a couple of Kg of tops so looking forward to following your procedure. I only have 3 litre beakers so will do them in small batches to minimise overflows. I would be really pleased to get 8 gm per Kg! Stay well and keep safe!

[@PickyPlans]

Thank you my friend ! I just prefer to process whole BGA once. Exactly mate. You need to do that in small batches its much safer. Yeah minimum 8 g per Kg why not. Just be aware of BGA quality you sort, to not be chinese from low quality LCD tv motherboards.

Hey , those flip green fibre chips contain good gold quantity a kg.Try detinning them in hydrochloric acid first then treat with aqua regia and stannous chloride .

[@PickyPlans]

There is just some gold spot on fiber . I'm not sure if it even reach 100 milligrams gold per kg stuff.

[@ilmarzeiger729]

Good videos, thank You!👍🤗🤗🥳

29:35 some sulfuric acid to form leed or silver sulfate nice video !!!

[@1lt3r]

You can use francois pellier method for tin 100 ml distill water 25 ml hno3 0,5 Gr urea 6gr citric acid

[@1lt3r]

And all tin will gone just like black powder and in this powder inside maybe have little amount Gold particules therefore you need filtering this solution and tin will be in the only solution

[@PickyPlans]

I've tested this Solution before... That was not able to prevent forming tin white paste (Metastannic acid) completely, when you have lots of tin to be leached. Also i recover tin from that white percipitate + charcoal in oven at 600° C. Anyway , Thanks for recipe. 🙏

hi picky are you from iran?

دمت گرم داداش خسته نباشی.یه پیشنهاد دارم البته بیشتر انتقاده :-) احساس میکنم خیلی زیاد توضیحات میدی در مورد کار که باعث میشه بیننده زود خسته بشه.البته این نظر منه و شتید اشتباه باشه.بهرحال دمت گرم که از روش های متفاوتی میخای به نتیجه برسی.موفق باشی

سلام ممنونم. مرسی از نظر خوبت ، راستش خودمم به همین نتیجه رسیدم برای ویدیو ها بعدی دیگه درنظر داشته باشم.... 🙏

Burning whole BGA is much cheaper for big quantities, instead using Sulfuric Acid, than AR.....

[@timvancourt7213]

@@PickyPlans I was planning on incinerating, grinding into a powder and going straight to aqua regia. Is that incorrect? What is Cupellation with lead? I could google that but I would rather hear your opinion! Thank you and wonderful video!!

[@timvancourt7213]

[@matthewhatch9141]

​@@PickyPlanscan Bismuth be used for this instead of lead?

[@walidmahmoud3957]

Hi, How can you precipitate lead from solution?

[@PickyPlans]

Best way to percipitate lead is in its sulfate form. So you need to add some sulfuric acid to your solution.

Hi How much gold does each kilo of Sis and Via chips give?

Hi 8-12 grams

If burning the all then we use cyanide method... Is it possible?

[@PickyPlans]

Yes it's possible just you need do something about copper. There is too much proportional copper amount. , So an inhibitor is needed. Also Process is much slower than acid method

[@bedadiabderrezzak1488]

@@PickyPlans which inhibitor you propose.

[@PickyPlans]

I would say MBT or nothing else . Nothing is good as MBT you see most of industrial refiners their cyanide bath is exactly colored as MBT is. I mean it's obvious they are using MBT. Another option is using low concentration Cyanide and high pH . The is still another option which I'm not sure about , and that's using pure ammonium quaternary salt (not Cetrimide) another salt and see how it works.

[@bedadiabderrezzak1488]

@@PickyPlans you mean that ammonium quaternary which is ammonium chloride works as an inhibitor.

[@PickyPlans]

No ammonium chloride on it's own isn't quaternary ammonium salt . Ammonium group should be conjugated with another group. Here is some examples alkyl dimethyl benzyl ammonium chloride, alkyl didecyl dimethyl ammonium chloride, and dialkyl dimethyl ammonium chloride. hexadecyltrimethylammonium ('cetrimide'), chlorhexidine, and benzalkonium chloride. Probably Cetrimide has gotten your attention. Well, if you find pure powder is good otherwise the pre prepared solutions are weak for cyanide
