GOLD RECOVERY LOW GRADE MIX PINS using Copper(II) chloride-CuCl2 solution. 

Seeing you videos makes me regret skipping all those chemistry classes in 1994 just to go shoot some pool… thanks for your videos and even though I’m not nearly at your level at metal refining… I would still play with you for those 0.7 grams at a pool table 😂

Great recovery here! Planning some e-waste recovery myself for this coming summer. Hope I can do as well. My plan is to mix everything together. Roasted chips, resistors, ribbon cables and mlcc's. Collect fingers from boards and throw it all in a beaker with AR. After silver recovery of course

Outstanding sir very informative thank you two thumbs

Thank you. From your other videos- your house looks beautiful.

Amazing video my bro. Very useful. Cheers and stay awesome.

Its crazy that sometimes when you add smb, that it turns white, then BAM its brown powder dropping out. Love these reactions

What do you do with the waste solution?

Good info thank you be safe everyone

Love these videos seeing the way you separate . But why don’t you ever do a melt video on you just separated. I think you should do one sometime big fan though.👍👍👏👏👏

Nice work 👍

عمل ممتاز استاذ إنشاء الله رزقك حلال

Nice video

Very good work

Not too bad My Friend!

cool 👍

Harika çalışma ustam ❤

Cheers Dusan

If you melt gold jewelry like rings necklaces and all that have karat marks like 10k 14k 18k and all do any of the other metals stay in the final product after its been melted or does the other metals go away and it just becomes strictly gold afterwards

šta ako ostavim otopinu bakar2klorida predugo pa se stvori bijeli talog na dnu tegle? dodati još hcl? treba li otopinu ap neutralizirati sa ureom? i može li se drop raditi u ap otopini sa kalijmetabisulfitom(vinobranom) ?

Nice👍

i would use new AP for this arent u worried about the copper dropping out of the copper 2 solution

Nice

Nice video idol

sweeeeet

Base metals are usually copper, why would you still add copper to HCI?

Well that answered a question, l was wondering if low grade pins were worth the effort of processing.. .. once again you have demonstrated the way to make it worth it, thank you Dusan

Can u use aqua regia on heat to remove gold from PC board pins quicker actually it's a mix of pins but mainly from mother boards ,,let me know a detailed process of that please

👍

hcl and sodium nitrate dissolves gold?

Piye kabare kang? Pleace give me your pin, aku jer rugi teros je.

Thumbs UP

ej brate you mention other videos you made. please link them

Doesn't matter whether or not they are magnetic?

Can you do a video of the recovery from magnetic pins

Sir it's all work to use full copper plz reply

After using that copper ll chloride solution, Can we reuse that solution again once more sir?

Another great video, but how pure are the gold foils before the final refine?

Electrólisis y no se pierde oro

Tried your silver recovery used sulfuric acid and sodium nitraite. Material turns dark red. What am I doing wrong

My issue with the CuCl2 method has to do with phosphor bronze base metals. Phosphor bronze is 5-8% tin. Tin in HCl forms stannous chloride. Copper chloride will etch gold, slowly, but it apparently does happen. Without tin being present, any etched gold is recemented out onto the base metals. But once stannous chloride is formed, any gold etched away becomes Purple of Cassius, also known as a positive stannous test. This is a coloidial solution that is difficult to deal with even by itself. Mixed with copper chloride, it's almost impossible to detect. I've seen the entire amount of plating dissolve and apparently disappear using the copper chloride process. Just be careful and try to avoid any tin when using this process.

watch he drops the powder ...all that work for nothing
