Can You Remove Gold Plating with Sodium Bisulfate?
Переглядів 94Місяць тому
in this video, I experiment with reverse electroplating to see if it can be done with sodium bisulfate, instead of the typical sulfuric acid. sulfuric acid can be difficult to get hold of in some countries, so I thought I would try a new method.

GOLD RECOVERY with SALT and VINEGAR!

in this video, I will recover gold foils from small circuit boards using salt vinegar and a little hydrogen peroxide.
Will vinyl tubes do for bubbling the NO2?
Vinyl will probably break down after a couple of uses. P.T.F.E tubing would be the best tubing to use. Thank you for watching
Appreciate your detailed explanations. Looking forward your next video. Thanks
Thank you for watching 👍
Love your new finding. God bless you🙏🙏🙏 me from Tamilnadu India
Yes I do the same way, except I use old pewter dishes from the flea market. Mostly there is a black residue left after the reaction ends. It not dissolve in fresh HCL, so I assume it´s Antimony. But I not yet try to heat it up and melt it.
just one question: You put in the SMB straight without denoxxing it? Well it seems to work.
I used just enough potassium nitrate to not need to de nox. De noxing is done to remove excess nitric. If you use enough to get the job done you will never need to de nox. Thanks for watching
Any way to speed up the process??
Using more hydrogen peroxide will speed up the process. If you change out the solution every few hours it would be done quicker. For me I wanted to do it the cheapest way possible and I have time to wait. Thanks for watching
@@3-2preciousmetalrecycling Awesome channel sir!
Thank you,the method followed by equation is very usefull
Thanks for watching
I thought this was a very good effort for a first video. I'm tempted to give this a go. Thanks for the information!
Thanks for watching I appreciate your feedback
Tempted to call this clickbait. It quickly devolved from "yeah, I got that stuff around the house" to "I don't have that shit in my house and nor will the pharmacy down the road".
Thanks for watching. You could use just the salt and vinegar to etch the copper from beneath the gold and bubble air through the solution . The hydrogen peroxide just speeds the process by oxidising the copper
The pharmacy down your street will absolutely have hydrogen peroxide I don’t think I’ve every been to a store that doesn’t
Amazon sells everything
